Towards glottal source controllability in expressive speech synthesis

In order to obtain more human like sounding humanmachine interfaces we must first be able to give them expressive capabilities in the way of emotional and stylistic features so as to closely adequate them to the intended task. If we want to replicate those features it is not enough to merely replicate the prosodic information of fundamental frequency and speaking rhythm. The proposed additional layer is the modification of the glottal model, for which we make use of the GlottHMM parameters. This paper analyzes the viability of such an approach by verifying that the expressive nuances are captured by the aforementioned features, obtaining 95% recognition rates on styled speaking and 82% on emotional speech. Then we evaluate the effect of speaker bias and recording environment on the source modeling in order to quantify possible problems when analyzing multi-speaker databases. Finally we propose a speaking styles separation for Spanish based on prosodic features and check its perceptual significance.

Methodology for developing a Speech into Sign Language Translation System in a New Semantic Domain

This paper proposes a methodology for developing a speech into sign language translation system considering a user-centered strategy. This method-ology consists of four main steps: analysis of technical and user requirements, data collection, technology adaptation to the new domain, and finally, evalua-tion of the system. The two most demanding tasks are the sign generation and the translation rules generation. Many other aspects can be updated automatical-ly from a parallel corpus that includes sentences (in Spanish and LSE: Lengua de Signos Española) related to the application domain. In this paper, we explain how to apply this methodology in order to develop two translation systems in two specific domains: bus transport information and hotel reception.

Fundamentos constructivos de las fortificaciones fronterizas entre las coronas de Castilla y Aragón de los siglos XII al XV en la actual provincia de Soria

La tesis doctoral desarrolla una investigación original, dentro del marco disciplinario de la historia de la construcción, sobre los fundamentos constructivos de las fortificaciones bajomedievales fronterizas entre las Coronas de Castilla y Aragón en la actual provincia de Soria. En el título de la tesis ya queda expresado el objeto fundamental y fundacional, así como el ámbito temporal —desde la reconquista del oriente soriano por parte de Alfonso I el Batallador a principios del siglo XII hasta la unificación de las coronas hispánicas en el siglo XV bajo el común mandato de los Reyes Católicos— y la extensión territorial que delimita la investigación: aquéllas comarcas castellanas lindantes con Aragón pertenecientes a la actual provincia de Soria. Durante este período bajomedieval se produjeron una serie de enfrentamientos fronterizos que obligó a fortificar la frontera y las vías de comunicación entre ambas coronas. La falta de estudios de conjunto de estas fortificaciones entendiéndolas como participantes en un sistema fortificado ha constituido la justificación de la investigación, que se realiza en varios niveles de análisis: territorial, histórico, arquitectónico, poliorcético y constructivo. Así mismo, se ha detectado cierta falta de rigor acompañada de inexactitudes en las consideraciones constructivas publicadas sobre algunas de las fortificaciones del ámbito de estudio, lo que ha provocado errores en su datación al no más haber elementos de corte artístico o estilístico que marquen indudablemente la pertenencia a una época. En la tesis se ponen en duda las dataciones tradicionalmente aceptadas planteando la hipótesis que da pie a la investigación: ante la falta de elementos artísticos o estilísticos en unos sobrios edificios eminentemente funcionales es posible establecer con suficiente aproximación la fecha de construcción en base a criterios constructivos una vez formada una clasificación cronotipológica de cada técnica constructiva. La hipótesis, por lo tanto, plantea un objetivo principal —el estudio de la razón constructiva del sistema fortificado fronterizo— desarrollado en una serie de objetivos específicos cuya consecución programa los sucesivos niveles de análisis: - Conocer y detallar los elementos históricos que originaron los enfrentamientos entre las Coronas de Castilla y Aragón y su desarrollo mediante herramientas historiográficas y analizar las características naturales del territorio en litigio mediante instrumentos cartográficos. - Conocer y analizar los tipos arquitectónicos y las tradiciones constructivas empleadas en las construcciones castrenses en el ámbito temporal en que se enmarca la investigación. - Localizar, documentar y seleccionar para su análisis las fortalezas y construcciones militares erigidas durante dichas luchas fronterizas en la actual provincia de Soria a través del trabajo de campo y métodos cartográficos y bibliográficos. - Realizar un estudio general sobre el sistema fortificado a escala territorial - Investigar la tipología arquitectónica, poliorcética y constructiva del conjunto de estas fortificaciones bajomedievales fronterizas. - Analizar los fundamentos constructivos de los casos de estudio seleccionados entre estas construcciones y caracterizarlas en cuanto al material, elementos, sistemas y procesos constructivos. - Ordenar la información histórica dispersa y corregir errores para hacer una base sobre la que establecer un discurso histórico de cada caso de estudio. - Comparar y relacionar las técnicas constructivas empleadas en estas fortalezas con los utilizados en el mismo ámbito temporal. - Difundir para su debate los resultados de la investigación por los foros científicos habituales. El método empleado combina los trabajos de gabinete con una intensa labor de campo, en la que se han documentado cincuenta fortificaciones y se han redactado sus correspondientes fichas de toma de datos. La recopilación de datos se ha incluido en una base de datos que incluye aspectos generales, tipológicos, constructivos y bibliográficos básicos del conjunto, a modo de inventario, de fortificaciones de la provincia. Las fortificaciones seleccionadas se agrupan según una clasificación tipológica y constructiva que marca las líneas de estudio posteriores. Se desarrolla un capítulo de antecedentes en el que se estudia la historia de la construcción fortificada medieval tanto en Europa como en España analizando la evolución de los tipos arquitectónicos y las múltiples influencias culturales que surcaron el Mediterráneo desde el Oriente cruzado e islámico al Poniente donde se desarrollaba la empresa reconquistadora que mantuvo en estado de guerra continuo a la Península Ibérica durante ochocientos años. El análisis del territorio como contenedor del hecho fortificado revela que hay una relación íntima entre la ubicación de las fortificaciones y las formas naturales que definen las vías de comunicación entre los valles del Duero, del Ebro y del Tajo. En efecto, el ámbito de estudio ha supuesto desde la Antigüedad un territorio de paso fundamental en la articulación de las comunicaciones en la Península Ibérica. Este carácter de paso más que de frontera explica las inquietudes y la preocupación por su control tanto por Roma como por el califato cordobés como por los reinos cristianos medievales. El análisis de los elementos históricos se complementa con el estudio detallado de los enfrentamientos fronterizos entre Castilla y Aragón así como los aspectos sociales y políticos que provocaron la fortificación como sistema de definición de la frontera y de organización espacial, jurisdiccional, social y administrativa del territorio. La arquitectura fortificada es esencialmente funcional: su cometido es la defensa. En este sentido, tras un estudio morfológico de los castillos seleccionados se realiza un extenso análisis poliorcético de sus elementos, investigando su origen y aplicación para servir también de parámetros de datación. Siendo el objeto inaugural de la tesis el estudio de los fundamentos constructivos, se explican los distintos materiales de construcción empleados y se agrupan las fábricas de las fortificaciones seleccionadas en dos grandes grupos constructivos: las fábricas aparejadas y las fábricas encofradas. Se han destacado y estudiado la evolución histórica y la tipología y mensiología constructiva de tres técnicas destacadas: el uso del ladrillo, la tapia de cal y canto o mampostería encofrada y la tapia de tierra. Para el estudio de la componente histórica y de la dimensión constructiva de cada técnica ha sido necesario documentar numerosos casos tanto en el ámbito de estudio como en la Península Ibérica con el fin de establecer grupos cronotipológicos constructivos entre los que poder ubicar las fábricas de estas técnicas presentes en el ámbito de estudio. Se ha observado una evolución dimensional de las fábricas de tapia que es más evidente en las hispanomusulmanas al modularse en codos pero que también se advierte significativamente en las cristianas bajomedievales. De cada una de las técnicas analizadas se ha seleccionado un caso de estudio singular y representativo. El castillo de Arcos de Jalón es un ejemplo significativo del empleo de la fábrica mixta de mampostería con verdugadas de ladrillo, así como las murallas de la ciudad fortificada de Peñalcázar lo es de la fábrica de mampostería encofrada y el castillo de Serón de Nágima constituye un caso característico y principal de la utilización de la tapia de tierra en la arquitectura militar bajomedieval. Cada uno de estos tres casos de estudios se examina bajo los mismos cuatro niveles anteriormente mencionados: territorial, histórico, arquitectónico y defensivo y constructivo. El sistemático método de estudio ha facilitado el orden en la investigación y la obtención de unos resultados y conclusiones que verifican la hipótesis y cumplen los objetivos marcados al comienzo. Se ha revisado la datación en la construcción de las fortificaciones analizadas mediante el estudio cronotipológico de sus fábricas, pudiendo trasladarse el método a otros sistemas fortificados. La tesis abre, finalmente, dos vías principales de investigación encaminadas a completar el estudio del sistema fortificado fronterizo bajomedieval en la raya oriental soriana de Castilla: la caracterización y datación por métodos físico-químicos de las muestras de piezas de madera de construcción que se conservan embebidas en las fábricas y la búsqueda documental y archivística que pueda revelar nuevos datos respecto a la fundación, reparación, venta o cualquier aspecto económico, legislativo, organizativo o administrativo relativo a las fortificaciones en documentos coetáneos. ABSTRACT The doctoral thesis develops an original research, held in the field of the Construction History, about the constructive reason of the frontier fortifications in the Late Middle Age between the Crowns of Castile and Aragón in the actual province of Soria, Spain. In the title is expressed the main objective, and also the temporal scope —from the reconquest in the 12th Century by Alfonso the First of Aragón to the unification under the common kingdom of the Catholic Kings— and the territorial extension that the research delimits: those Castilian regions in the border with Aragón in the actual province of Soria. During this period, a series of border wars were been, and this is the reason for the fortification of the border line and the main roads between both Crowns. The lack of studies of these fortifications as participants in a fortified system is the justification of the research. There is several analysis levels: territorial, historical, architectonic, defensive and constructive. Likewise, there is a lack of strictness and inaccuracy in the constructive items in the publications about several fortifications of this study field. This aspect has caused mistakes in the dating because there is neither artistic nor stylistic elements which determines a epoch. The traditionally accepted datings are challenged. An hypothesis is formulated: in the absence of artistic or stylistic elements in a sober and functional buildings is possible to date the time of construction with sufficiently approximation based on construction criteria once formed a cronotypologic classification of each building technique. The hypothesis, therefore, propose a main aim: the study of the constructive reason of the fortified border system. This aim is developed in a series of specifically targets whose achievement programs the analysis levels: - To know and to detail the historical elements which started the wars between Castile and Aragon and its development using historiographical tools, and to analyze the natural characteristic of the territory through cartographical tools. - To understand and to analyze the different architectural types and the building traditions employed in the military buildings in the time researched. - To locate, to document, and to select for their analysis the fortresses and military constructions erected during these border wars in the actual province of Soria through fieldwork and bibliographical and cartographical methods. - To conduct a general study on the fortified system in territorial scale. - To research the architectural, constructive and defensive typology of the system of these border late medieval fortifications. - To analyze the construction logic of the selected case studies and to characterize in the items of material, elements, systems and construction processes. - To sort scattered historical information and to correct mistakes to make a base by which to establish a historic speech of each case study. - To compare and to relate the construction techniques employed in these fortresses with those used in the same time range . - To spread for discussion the research results in the usual scientists forums. The method combines the destock work with an intense fieldwork. Fifty fortifications have been documented and it has written their corresponding data collection card. Data collection has been included in a database that includes general aspects, typological, constructive and basic bibliographical data, as an inventory of fortifications in the province. The selected fortifications are grouped according to a typological and constructive classification which lead the lines of the later study. There is a chapter for the antecedents in which the history of the medieval fortified construction in Europe and in Spain is studied by analyzing the evolution of architectural types and the many cultural influences along the opposite seasides of the Mediterranean Sea, from the Islamic and Crusader East to the Iberian Peninsula in where there were a long and continuous war during eight hundred years. The territory is analyzed as a container of fortifications. This analysis reveals that there is an intimate relationship between the location of the fortifications and the natural forms that define the communication roads between the Duero, Ebro and Tajo valleys. Indeed, the study area has been a cross-territory from ancient times more than a frontierterritory. This communication character explains the concerns about its control both by Rome and by the Muslims of Córdoba as medieval Christian kingdoms. The analysis of historical elements is supplemented by detailed study of border war between Castile and Aragon and the social and political issues that led to the fortification as border definition system and spatial, jurisdictional, social and administrative planning. The fortified architecture is essentially functional: it is responsible for defense. In this sense, after a morphological study of selected castles is performed an extensive analysis of its defensive elements, investigating its origin and application. This analisis serves for the definition of parameters for dating. The purpose of the thesis is the study of the constructive logic. First, various building materials are explained. Then, masonry is grouped into two major constructive groups: rigged masonry and formwork masonry. The historical evolution and the constructive typology and mensiology are studied for each one of the three main techniques: the use of brickwork, the mortar wall and rammed-earth. Many case studies have been documented along the Iberian Peninsula and also in the study area. As conclusion, there is a dimensional evolution of the rammed-earth walls. This evolution is more evident into the Muslim masonry than in the late medieval walls: the reason is the use of the cubit as module. From each of the techniques discussed, a singular and representative case of study has been selected. The castle of Arcos de Jalon is a significant example of mix masonry of stone and brick rows. The walled city of Peñalcázar is built with masonry formwork. Serón de Nágima castle, at last, is a typical and main case of the use of the rammedearth wall of late medieval military architecture. Each of these three case studies were examined under the same four analysis levels above mentioned: territorial, historical, architectural and defensive and constructive. The systematic method of study has facilitated the order in the research and the obtaining of results and conclusions that verify the hypotheses and achieve the research objectives. Dating of the fortifications construction has been revised by studying the cronotypological issues of its masonry. The method can be transferred to the study of other fortified systems. Finally, the thesis describes two main research new ways aimed at completing the study of the late medieval fortified border of Castile in the actual province of Soria. The first of them is the characterization and datig by physicochemical methods the sample pieces of wood construction preserved embedded in the masonry. The second research way is the investigation of the documents in archives that may reveal new information about the foundation, repair, sale or any aspect to economic, legal, organizational or administrative concerning fortifications in contemporary documents.

On the dynamic adaptation of language models based on dialogue information

We present an approach to adapt dynamically the language models (LMs) used by a speech recognizer that is part of a spoken dialogue system. We have developed a grammar generation strategy that automatically adapts the LMs using the semantic information that the user provides (represented as dialogue concepts), together with the information regarding the intentions of the speaker (inferred by the dialogue manager, and represented as dialogue goals). We carry out the adaptation as a linear interpolation between a background LM, and one or more of the LMs associated to the dialogue elements (concepts or goals) addressed by the user. The interpolation weights between those models are automatically estimated on each dialogue turn, using measures such as the posterior probabilities of concepts and goals, estimated as part of the inference procedure to determine the actions to be carried out. We propose two approaches to handle the LMs related to concepts and goals. Whereas in the first one we estimate a LM for each one of them, in the second one we apply several clustering strategies to group together those elements that share some common properties, and estimate a LM for each cluster. Our evaluation shows how the system can estimate a dynamic model adapted to each dialogue turn, which helps to improve the performance of the speech recognition (up to a 14.82% of relative improvement), which leads to an improvement in both the language understanding and the dialogue management tasks.

Developing an information system for deaf

This paper presents the SAILSE Project (Sistema Avanzado de Información en Lengua de Signos Española ? Spanish Sign Language Advanced Information System). This project aims to develop an interactive system for facilitating the communication between a hearing and a deaf person. The first step has been the linguistic study, including a sentence collection, its translation into LSE (Lengua de Signos Española - Spanish Sign Language), and sign generation. After this analysis, the paper describes the interactive system that integrates an avatar to represent the signs, a text to speech converter and several translation technologies. Finally, this paper presents the set up carried out with deaf people and the main conclusions extracted from it.

The analysis of the basketball coach speech during the moments of game and pause in relation to the performance in competition

In the area of the professional competition, the coach is a fundamental part in the management of a team and more concretely in the game planning. During the competition, the management of the times of pause and times out as well as the conduct of the coach during the same ones is an aspect to analyze in the sports performance. It is for this that it becomes necessary to know some of the behaviors that turn out to be more frequent by the coach and that are more related to a positive performance of his players. For it there has been realized a study of 7 cases of expert coaches in those that his verbal behavior has observed during 4 games. It has focused on the content of the information only to verbal level, on his meaning. The information that have been obtained in the study shows a major quantity of information elaborated during the pauses of the games and a major tactical content with regard to the moments of game. On the other hand, a relation exists between a major number of questions and a minor number of psychological instructions when the score is adverse, whereas in case of victory, a direct relation does not exist with any category. The rest of categories of the speech do not meet influenced directly for the result, for what it is not possible to consider a direct and immediate relation between the coach verbal behavior during the pauses and the result of the game, except in punctual moments.

Adaptive spatio-temporal filter for low-cost camera depth maps

In this paper we present an adaptive spatio-temporal filter that aims to improve low-cost depth camera accuracy and stability over time. The proposed system is composed by three blocks that are used to build a reliable depth map of static scenes. An adaptive joint-bilateral filter is used to obtain consistent depth maps by jointly considering depth and video information and by adapting its parameters to different levels of estimated noise. Kalman filters are used to reduce the temporal random fluctuations of the measurements. Finally an interpolation algorithm is used to obtain consistent depth maps in the regions where the depth information is not available. Results show that this approach allows to considerably improve the depth maps quality by considering spatio-temporal information and by adapting its parameters to different levels of noise.

Efficient spatio-temporal hole filling strategy for Kinect depth maps

In this paper we present an efficient hole filling strategy that improves the quality of the depth maps obtained with the Microsoft Kinect device. The proposed approach is based on a joint-bilateral filtering framework that includes spatial and temporal information. The missing depth values are obtained applying iteratively a joint-bilateral filter to their neighbor pixels. The filter weights are selected considering three different factors: visual data, depth information and a temporal-consistency map. Video and depth data are combined to improve depth map quality in presence of edges and homogeneous regions. Finally, the temporal-consistency map is generated in order to track the reliability of the depth measurements near the hole regions. The obtained depth values are included iteratively in the filtering process of the successive frames and the accuracy of the hole regions depth values increases while new samples are acquired and filtered

Generating descriptions that summarize geospatial and temporal data

Effective data summarization methods that use AI techniques can help humans understand large sets of data. In this paper, we describe a knowledge-based method for automatically generating summaries of geospatial and temporal data, i.e. data with geographical and temporal references. The method is useful for summarizing data streams, such as GPS traces and traffic information, that are becoming more prevalent with the increasing use of sensors in computing devices. The method presented here is an initial architecture for our ongoing research in this domain. In this paper we describe the data representations we have designed for our method, our implementations of components to perform data abstraction and natural language generation. We also discuss evaluation results that show the ability of our method to generate certain types of geospatial and temporal descriptions.

Estimación y evolución temporal de variables forestales con tecnología LiDAR en el Valle de la Fuenfría (Cercedilla, Madrid)

Este estudio profundiza en la estimación de variables forestales a partir de información LiDAR en el Valle de la Fuenfría (Cercedilla, Madrid). Para ello se dispone de dos vuelos realizados con sensor LiDAR en los años 2002 y 2011 y en el invierno de 2013 se ha realizado un inventario de 60 parcelas de campo. En primer lugar se han estimado seis variables dasométricas (volumen, área basimétrica, biomasa total, altura dominante, densidad y diámetro medio cuadrático) para 2013, tanto a nivel de píxel como a nivel de rodal y monte. Se construyeron modelos de regresión lineal múltiple que permitieron estimar con precisión dichas variables. En segundo lugar, se probaron diferentes métodos para la estimación de la distribución diamétrica. Por un lado, el método de predicción de percentiles y, por otro lado, el método de predicción de parámetros. Este segundo método se probó para una función Weibull simple, una función Weibull doble y una combinación de ambas según la distribución que mejor se ajustaba a cada parcela. Sin embargo, ninguno de los métodos ha resultado suficientemente válido para predecir la distribución diamétrica. Por último se estimaron el crecimiento en volumen y área basimétrica a partir de la comparación de los vuelos del 2002 y 2011. A pesar de que la tecnología LiDAR era diferente y solo se disponía de un inventario completo, realizado en 2013, los modelos construidos presentan buenas bondades de ajuste. Asimismo, el crecimiento a nivel de pixel se ha mostrado estar relacionado de forma estadísticamente significativa con la pendiente, orientación y altitud media del píxel. ABSTRACT This project goes in depth on the estimation of forest attributes by means of LiDAR data in Fuenfria’s Valley (Cercedilla, Madrid). The available information was two LiDAR flights (2002 and 2011) and a forest inventory consisting of 60 plots (2013). First, six different dasometric attributes (volume, basal area, total aboveground biomass, top height, density and quadratic mean diameter) were estimated in 2013 both at a pixel, stand and forest level. The models were developed using multiple linear regression and were good enough to predict these attributes with great accuracy. Second, the measured diameter distribution at each plot was fitted to a simple and a double Weibull distribution and different methods for its estimation were tested. Neither parameter prediction method nor percentile prediction method were able to account for the diameter distribution. Finally, volume and top height growths were estimated comparing 2011 LiDAR flight with 2002 LiDAR flight. Even though the LiDAR technology was not the same and there was just one forest inventory with sample plots, the models properly explain the growth. Besides, growth at each pixel is significantly related to its average slope, orientation and altitude.

AquaData and AquaGIS: Two computer utilities for temporal and spatial simulations of water-limited yield with AquaCrop.

The crop simulation model AquaCrop, recently developed by FAO can be used for a wide range of purposes. However, in its present form, its use over large areas or for applications that require a large number of simulations runs (e.g., long-term analysis), is not practical without developing software to facilitate such applications. Two tools for managing the inputs and outputs of AquaCrop, named AquaData and AquaGIS, have been developed for this purpose and are presented here. Both software utilities have been programmed in Delphi v. 5 and in addition, AquaGIS requires the Geographic Information System (GIS) programming tool MapObjects. These utilities allow the efficient management of input and output files, along with a GIS module to develop spatial analysis and effect spatial visualization of the results, facilitating knowledge dissemination. A sample of application of the utilities is given here, as an AquaCrop simulation analysis of impact of climate change on wheat yield in Southern Spain, which requires extensive input data preparation and output processing. The use of AquaCrop without the two utilities would have required approximately 1000 h of work, while the utilization of AquaData and AquaGIS reduced that time by more than 99%. Furthermore, the use of GIS, made it possible to perform a spatial analysis of the results, thus providing a new option to extend the use of the AquaCrop model to scales requiring spatial and temporal analyses.

Temporal task allocation in periodic environments. An approach based on synchronization

In this paper, we study a robot swarm that has to perform task allocation in an environment that features periodic properties. In this environment, tasks appear in different areas following periodic temporal patterns. The swarm has to reallocate its workforce periodically, performing a temporal task allocation that must be synchronized with the environment to be effective. We tackle temporal task allocation using methods and concepts that we borrow from the signal processing literature. In particular, we propose a distributed temporal task allocation algorithm that synchronizes robots of the swarm with the environment and with each other. In this algorithm, robots use only local information and a simple visual communication protocol based on light blinking. Our results show that a robot swarm that uses the proposed temporal task allocation algorithm performs considerably more tasks than a swarm that uses a greedy algorithm.

Translating bus information into sign language for deaf people

This paper describes the application of language translation technologies for generating bus information in Spanish Sign Language (LSE: Lengua de Signos Española). In this work, two main systems have been developed: the first for translating text messages from information panels and the second for translating spoken Spanish into natural conversations at the information point of the bus company. Both systems are made up of a natural language translator (for converting a word sentence into a sequence of LSE signs), and a 3D avatar animation module (for playing back the signs). For the natural language translator, two technological approaches have been analyzed and integrated: an example-based strategy and a statistical translator. When translating spoken utterances, it is also necessary to incorporate a speech recognizer for decoding the spoken utterance into a word sequence, prior to the language translation module. This paper includes a detailed description of the field evaluation carried out in this domain. This evaluation has been carried out at the customer information office in Madrid involving both real bus company employees and deaf people. The evaluation includes objective measurements from the system and information from questionnaires. In the field evaluation, the whole translation presents an SER (Sign Error Rate) of less than 10% and a BLEU greater than 90%.

Language recognition using phonotactic-based shifted delta coefficients and multiple phone recognizers

A new language recognition technique based on the application of the philosophy of the Shifted Delta Coefficients (SDC) to phone log-likelihood ratio features (PLLR) is described. The new methodology allows the incorporation of long-span phonetic information at a frame-by-frame level while dealing with the temporal length of each phone unit. The proposed features are used to train an i-vector based system and tested on the Albayzin LRE 2012 dataset. The results show a relative improvement of 33.3% in Cavg in comparison with different state-of-the-art acoustic i-vector based systems. On the other hand, the integration of parallel phone ASR systems where each one is used to generate multiple PLLR coefficients which are stacked together and then projected into a reduced dimension are also presented. Finally, the paper shows how the incorporation of state information from the phone ASR contributes to provide additional improvements and how the fusion with the other acoustic and phonotactic systems provides an important improvement of 25.8% over the system presented during the competition.
