Acoustic analysis of speech through a hearing aid: perceptual effects of changes with two-channel compression

Compression amplification significantly alters the acoustic speech signal in comparison to linear amplification. The central hypothesis of the present study was that the compression settings of a two-channel aid that best preserved the acoustic properties of speech compared to linear amplification would yield the best perceptual results, and that the compression settings that most altered the acoustic properties of speech compared to linear would yield significantly poorer speech perception. On the basis of initial acoustic analysis of the test stimuli recorded through a hearing aid, two different compression amplification settings were chosen for the perceptual study. Participants were 74 adults with mild to moderate sensorineural hearing impairment. Overall, the speech perception results supported the hypothesis. A further aim of the study was to determine if variation in participants' speech perception with compression amplification (compared to linear amplification) could be explained by the individual characteristics of age, degree of loss, dynamic range, temporal resolution, and frequency selectivity; however, no significant relationships were found.

Voice and speech characteristics and vocal hygiene in novice and professional voice broadcast journalists

Knowledge of differences in voice and speech characteristics between novice and professional broadcasters is essential for effective education of broadcast journalism students. Because newsreaders rely on optimal voice production, information pertaining to vocal hygiene is also important. The first aim of this study was to compare the voice and speech characteristics of professional newsreaders, student newsreaders and control participants. The second aim was to compare the awareness and use of vocal hygiene across these groups. Professional radio newsreaders, broadcast journalism students and two matched control groups were included in the study. Each participant recorded a news bulletin and completed a questionnaire on vocal hygiene. Data analysis of the recording included objective analysis and perceptual ratings by a panel of three judges. Significant student-professional differences were found. Compared to both the students and the control groups, the professional newsreaders had greater variation in speaking fundamental frequency, a faster rate of speech, fewer pronunciation errors and higher perceptual ratings on vocal quality, emphasis, continuity, phrasing and style of newsreading. Female professional newsreaders had a higher speaking fundamental frequency than both their control participants and the student newsreaders. Comparison of vocal hygiene awareness revealed few significant differences between any of the groups.

Mitigated directness in Honglou meng: directive speech acts and politeness in eighteenth century Chinese

This paper is situated within a theoretical discussion that asserts a positive correlation between indirectness and politeness, and uses these claims as a springboard for an examination of polite ways of issuing directives in eighteenth century Chinese. On the basis of an analysis of directive speech acts from dialogue in the novel Honglou meng, it argues that the concept of indirectness, as it applies to the illocutionary transparency of individual speech acts, has no particular value in the culture and language of eighteenth century Chinese men. It is found that other linguistic devices such as particles, the reduplication of verbs, terms of address, and the presence and sequencing of supportive moves are far more significant to the communication of politeness. The findings suggest a need to rethink current theoretical positions on this subject and move beyond the analysis of individual speech acts to examine the role discourse structure and management play in the enactment of politeness.

Práticas de comunicação audiovisual participativa: apresentação de um caso de estudo no contexto das instituições culturais

Nesta comunicação apresentaremos as metodologias e conclusões previstas da primeira fase do trabalho de construção de narrativas audiovisuais participativas relacionadas com o projeto “Manobras no Porto”, que irá servir de caso de estudo para o projeto de investigação intitulado: “The Museum of All: Práticas de Comunicação Institucional num Mundo de Redes Participativas”. Recorrendo a técnicas de observação participante, nesta primeira fase, o objectivo é mapear o posicionamento dos parceiros do projeto em estudo e identificar as suas ações de dinamização cultural, recolher informações sobre as problemáticas sociais, económicas e culturais da zona de intervenção do projeto e auscultar os públicos intervenientes sobre as prioridades nos seus quotidianos e vivências. Posteriormente, passaremos a uma fase de proposição, com o objectivo de analisar contextos de cooperação, participação e envolvimento das comunidades na criação colectiva de novas mensagens e narrativas, através da implementação de um conjunto de exercícios audiovisuais participativos.

Espectador Activo: Comunicação audiovisual institucional num mundo de redes participativas

Once delighted by the moving image advent as a new method of realistically presenting reality, the viewer has been reposition himself towards the audiovisual contents he consumes, as he is given the opportunity to create and share his own perspective of that reality. We are living in a new technological setting, governed mainly by factors of interactivity, digital systems and technological convergence. The research project that we will present in this paper focuses on the subject of participatory media and the way cultural institutions are increasingly facing the inevitability of a profound revision of their traditional parameters of unidirectional communication, given the increasing availability of tools for audiovisual production as well as the diversity of networked communication contexts. The Serralves Foundation with its Museum of Contemporary Art, in Porto, Portugal, was the subject of a fi rst study of an empirical nature: a series of audiovisual objects were developed, in order to generate material for analysis and proposition. In this new stage of the project, our aim is to identify new procedures and practices that may be effectively implemented within the institutional universe. We intend to propose effi cient audiovisual communication contexts, including the maximizing of the relationship between institutions and audiences regarding dimensions that are traditionally outside the institutional radar: identity, narrative and affection. The project is currently in the process of surveying and categorization, with the aim of producing a map of different vocations and positions of the various institutions in regards to the aforementioned issues, which require participatory communication.

Resultados preliminares de um estudo sobre tradução audiovisual infanto-juvenil: o caso da dobragem em Portugal

Nos últimos anos, o volume de produções audiovisuais aumentou exponencialmente graças ao desenvolvimento das novas tecnologias e à omnipresença dos mass media à escala global. No que concerne o público infanto- juvenil, o consumo massivo de produtos audiovisuais contribuiu para a construção de um novo tipo de espectador mais familiarizado com a imagem/palavra em movimento, seja no ecrã da televisão ou do computador. Com este artigo, pretendo partilhar os resultados preliminares de um estudo exploratório sobre o impacto da dobragem em Portugal no público infanto- juvenil enquanto consumidores/receptores deste tipo de tradução interlinguística. Considerando que a oferta televisiva é condicionante do tipo de consumo de produtos audiovisuais traduzidos é crucial compreender de que modo esta conjuntura poderá vir a criar públicos mais receptivos à dobragem num futuro próximo.

Produção de sentido na linguagem audiovisual através da montagem

Este texto é sobre os problemas e as soluções associadas com a produção de sentido de modo cinematográfico nos discursos audiovisuais. O enfoque centra-se na resposta à pergunta de como o texto e leitor criam o sentido e não tanto em qual é o significado do texto. Associado a este objectivo propomos identificar os limites expressivos do discurso cinematográfico que não recorre à verbalização e as capacidades que a linguagem cinematográfica tem vindo a desenvolver para exprimir conceitos cada vez mais complexos apesar de a representação visual estar limitada ao registo visual de objectos, pessoas e acções. Este estudo insere-se no campo da retórica visual e da literacia visual que se dedicam ao estudo dos processos através dos quais se produz, manipula e interpreta sentido através das imagens. No entanto porque estamos a estudar um discurso que se organiza no tempo e que contêm a imagem, palavra e som podemos inserir este estudo na disciplina da Retórica cinematográfica que é uma área científica contida dentro da semiótica e que se dedica ao estudo sobre porquê e como é que o discurso audiovisual produz sentido. O motivo que deu origem a este estudo tem origem no ensino de cadeiras sobre linguagem audiovisual a alunos universitários que tiveram doze anos de alfabetização mas nunca reflectiram sobre como se exprimem ideias sem o uso da palavra uma vez que o principal objectivo da escolaridade é tornar os alunos capazes de saberem interpretar e expressarem-se através da linguagem verbal. A consequência deste processo de aprendizagem é que quando se pede a uma pessoa com formação literária para se expressar num discurso audiovisual deparamos com filmes onde o sentido do discurso é feito com base no texto que é verbalizado numa voz off ou nos diálogos que são ditas por personagens de uma ficção.

Three-dimensional modeling of tongue during speech using MRI data

The tongue is the most important and dynamic articulator for speech formation, because of its anatomic aspects (particularly, the large volume of this muscular organ comparatively to the surrounding organs of the vocal tract) and also due to the wide range of movements and flexibility that are involved. In speech communication research, a variety of techniques have been used for measuring the three-dimensional vocal tract shapes. More recently, magnetic resonance imaging (MRI) becomes common; mainly, because this technique allows the collection of a set of static and dynamic images that can represent the entire vocal tract along any orientation. Over the years, different anatomical organs of the vocal tract have been modelled; namely, 2D and 3D tongue models, using parametric or statistical modelling procedures. Our aims are to present and describe some 3D reconstructed models from MRI data, for one subject uttering sustained articulations of some typical Portuguese sounds. Thus, we present a 3D database of the tongue obtained by stack combinations with the subject articulating Portuguese vowels. This 3D knowledge of the speech organs could be very important; especially, for clinical purposes (for example, for the assessment of articulatory impairments followed by tongue surgery in speech rehabilitation), and also for a better understanding of acoustic theory in speech formation.

Analysis of tongue shape and motion in speech production using statistical modeling

The mechanisms of speech production are complex and have been raising attention from researchers of both medical and computer vision fields. In the speech production mechanism, the articulator’s study is a complex issue, since they have a high level of freedom along this process, namely the tongue, which instigates a problem in its control and observation. In this work it is automatically characterized the tongues shape during the articulation of the oral vowels of Portuguese European by using statistical modeling on MR-images. A point distribution model is built from a set of images collected during artificially sustained articulations of Portuguese European sounds, which can extract the main characteristics of the motion of the tongue. The model built in this work allows under standing more clearly the dynamic speech events involved during sustained articulations. The tongue shape model built can also be useful for speech rehabilitation purposes, specifically to recognize the compensatory movements of the articulators during speech production.

Audiovisual translation on Portuguese news bulletin

The daily access to news broadcast is something that, generally speaking, we do not abstain ourselves from, whether it is to be aware of what is going on in our country or to be informed about international events. But are we attentive to how the information about those events, namely those that occur outside Portugal, reaches us? How is that information handled – and who handles it – until we have it at our disposal? Is the audience aware that a large part of the news must be translated and must have a linguistic treatment? And how can we describe that same translation and the way it is presented? This case study is just an example of translation‘s role and its crucial presence on TV news broadcast, considering the way translation is processed, how it is barely noticed – or not –, how it influences the construction of the story and how the story influences the translation process. This case study was presented at the 2nd International Conference ―Media for All‖, with the theme ―Text on Air, Text on Screen‖, which took place at the Polytechnic Institute of Leiria, on 7-9 November 2007. O acesso diário a serviços informativos noticiosos é algo de que, de um modo geral, não nos privamos, seja para ficar a par do que se passa no nosso país, seja para ficarmos mais informados sobre eventos e acontecimentos internacionais. Mas teremos noção de como essas informações sobre esses acontecimentos, nomeadamente os que têm lugar fora de Portugal, chegam até nós? Qual será o tratamento dado a essas informações – e quem trata essas informações – até serem colocadas à nossa disposição? Será que o público, de um modo geral, se apercebe que grande parte das notícias é alvo de tratamento tradutológico e linguístico? E como se caracterizará essa tradução e a forma de apresentação da mesma? O presente estudo de caso é apenas um exemplo do papel e da presença fulcral da tradução em serviços noticiosos televisivos, seja pela forma como é feita, pelo modo como passa despercebida (ou não), pela influência que terá na construção da peça noticiosa e pela influência que a peça noticiosa terá no modo como se processa a tradução. Este estudo de caso foi apresentado na 2ª Conferência Internacional ―Media for All‖, subordinada ao tema ―Text on Air, Text on Screen‖, que teve lugar no Instituto Politécnico de Leiria de 7 a 9 de Novembro de 2007.

Phonological and articulation treatment approaches in Portuguese children with speech and language impairments: a randomized controlled intervention study

Background: In Portugal, the routine clinical practice of speech and language therapists (SLTs) in treating children with all types of speech sound disorder (SSD) continues to be articulation therapy (AT). There is limited use of phonological therapy (PT) or phonological awareness training in Portugal. Additionally, at an international level there is a focus on collecting information on and differentiating between the effectiveness of PT and AT for children with different types of phonologically based SSD, as well as on the role of phonological awareness in remediating SSD. It is important to collect more evidence for the most effective and efficient type of intervention approach for different SSDs and for these data to be collected from diverse linguistic and cultural perspectives. Aims: To evaluate the effectiveness of a PT and AT approach for treatment of 14 Portuguese children, aged 4.0–6.7 years, with a phonologically based SSD. Methods & Procedures: The children were randomly assigned to one of the two treatment approaches (seven children in each group). All children were treated by the same SLT, blind to the aims of the study, over three blocks of a total of 25 weekly sessions of intervention. Outcome measures of phonological ability (percentage of consonants correct (PCC), percentage occurrence of different phonological processes and phonetic inventory) were taken before and after intervention. A qualitative assessment of intervention effectiveness from the perspective of the parents of participants was included. Outcomes & Results: Both treatments were effective in improving the participants’ speech, with the children receiving PT showing a more significant improvement in PCC score than those receiving the AT. Children in the PT group also showed greater generalization to untreated words than those receiving AT. Parents reported both intervention approaches to be as effective in improving their children’s speech. Conclusions & Implications: The PT (combination of expressive phonological tasks, phonological awareness, listening and discrimination activities) proved to be an effective integrated method of improving phonological SSD in children. These findings provide some evidence for Portuguese SLTs to employ PT with children with phonologically based SSD
