The purpose of this research was to analyse the phonological system of the Limi dialect of Humla Bhotia. Humla Bhotia is a Tibeto-Burman language that is spoken by approximately 4000 5000 people in the far northwestern Humla province of the Kingdom of Nepal. The language has not previously been the subject of analysis. The data base for this thesis was collected on two different dialects of Humla Bhotia in Kathmandu, the capital of Nepal, from February to May 2000. I had three language informants who speak Humla Bhotia as their mother tongue. One of the informants speaks the Upper Humla dialect and the other two informants speak the Limi dialect. In this thesis I have concentrated on the phonology of the dialect of Limi but occasionally I also make reference to the Upper Humla dialect. The Limi data base consists of 600 words elicited in isolation, sentences where words have been checked for consonantal and pitch variation, and five texts comprising 117 sentences. Firstly, I have studied the geographical location, population and dialects of Humla Bhotia. Five dialects were identified: Limi, Upper Humla, La Yakba, Nyinba and Humli Khyampa. Information on the dialect areas is based on the accounts of seven mother tongue speakers of the language and on Nancy Levine s (1988) anthropological research of the ethnic group Nyinba. Secondly, I have analysed the phonological system of Limi from the viewpoint of American stucturalism much along the lines followed by Pike 1966 [1947] ja 1967 [1948]. In defining the prosodic elements I have also used acoustic analysis. In the Limi dialect there are 7 vowel phonemes. No vowel clusters occur within the same syllable. In this preliminary analysis 29 contrastive plosives, 8 affricates and 5 6 fricatives were found. The data also revealed 4 nasal phonemes, two rhotic phonemes, one lateral phoneme and two central approximants. Further research is however called for to check the phonemic status of these segments. Four contrastive prosodic elements were encountered: nasalisation, length, phonation type and pitch movement. There are two contrastive types of phonation: tense and lax. Many words were found with a third type of phonation, modal phonation. How modal phonation relates to the prosodic system is unclear at this stage and is therefore left for further research to determine. There are two contrastive pitch movement tonemes: a rising toneme and falling toneme. The falling toneme occurs in free variation with a level pitch contour. Rising appears to be linked with lax phonation and falling with tense phonation.

This thesis is a preliminary phonological description of the Tibetan-related Denjongka language of Sikkim, India. Because the language has not been much researched and the previous studies have focused on other issues than phonology, the present paper is the first of its kind. The data for this thesis was gathered in Gangtok, the capital of Sikkim, from March to May 2004. I had four language informants from four different locations in Sikkim who spoke different dialects of Denjongka. One of the informants, from whom I recorded c. 900 words and 530 sentences, was used as the main data source for the analysis. First, I will give some ethnographic background information on the people who speak Denjongka. Next, I will discuss first the segmental and then the suprasegmental phonology of the language, which were analysed much in line with American structuralism. I also used acoustic analysis enabled by the Praat-program. Eight vowel phonemes were found. The phonemic status of /E/, however, is still suspect. I present some preliminary evidence for roundedness, frontness and height assimilation among the vowels. In the interpretation adopted in this analysis, there are no diphthongs in Denjongka. Forty consonant phonemes were found: 17 plosives, 7 affricates, 5 fricatives, 5 nasals, 4 liquids and 2 approximants. Denjongka plosives and affricates have four-way aspiration/voicing distinction: voiceless aspirated, voiceless unaspirated, voiceless slightly aspirated (devoiced), and voiced unaspirated. Two voiceless nasals and two voiceless liquids were found. Two phonation types were found to be contrastive, lax/breathy and tense/creaky. Nasalisation and length in vowels are phonemic. Denjongka is an incipient tone language. Tonal phenomena, which involve mainly pitch and phonation type, are complex. Pitch is most of the time predictable from the initial consonant and the phonation type. In some cases, however, pitch is the only contrastive feature between words. The description of Denjongka in this paper differs from the traditional four-tone system, which has been used in many descriptions of Tibetan-related languages. In the four-tone system, pitch is contrastive both in the high and low register, whereas in the present analysis pitch has been established to contrast only in the high register. Lastly, the appendices include a comparative word list of the four Denjongka dialects studied in this thesis.

[ES] Este artículo trata sobre el proceso fonológico que en euskera convierte en africadas las fricativas sibilantes tras consonante sonante. El análisis de dicho proceso es particularmente adecuado para la discusión de la relación recíproca entre fonética y fonología tal y defendida por la Fonología Natural. Es ese marco teórico, este trabajo estudia la motivación fonética de la fonología; por otro lado, explora las consecuencias perceptivas –tal vez también productivas– de los distintos inventarios fonémicos de cada lengua, comparando el proceso de africación vasco con el más conocido proceso inglés de inserción oclusiva. Se argumenta que la opción terminológica africación vs. inserción podría no ser una cuestión trivial sino el reflejo de alguna diferencia en el procesamiento fonológico de condiciones fonéticas básicamente equivalentes. La optimización de la estructura silábica se presenta como otro posible elemento de la configuración del proceso y como factor que contribuye a la mayor o menor relevancia de éste en lenguas tipológicamente distintas. Se ofrecen en la sección 3 algunos comentarios sobre imágenes espectrográficas como muestra de las observaciones que dieron lugar al trabajo de investigación en curso.

Approximants that can be considered weaker versions of voiced fricatives (termed here ‘frictionless continuants’) are poorly served by the IPA in terms of symbolization as compared to semi-vowel approximants. In this paper we survey the central approximants and the symbols and diacritics used to transcribe them; we focus on evidence for the use of non-rhotic frictionless continuants in both natural language (by which we mean non-clinical varieties) and disordered speech; and we suggest some possible unitary symbols for those that currently require the use of a hard-to-read lowering diacritic beneath the symbol for the corresponding voiced fricative.

OBJETIVO: Verificar os desempenhos perceptual-auditivo e ortográfico de escolares no que se refere à identificação de contrastes entre as fricativas do Português Brasileiro, e investigar em que medida esses dois tipos de desempenhos se relacionam. MÉTODOS: Foram analisados dados de desempenho perceptual-auditivo e de desempenho ortográfico extraídos de 20 crianças das duas primeiras séries do ensino fundamental de uma escola pública do município de Mallet (PR). A coleta de dados de percepção auditiva foi feita com base no Instrumento de Avaliação da Percepção de Fala (PERCEFAL), com o uso do software Perceval. Já a coleta de dados de ortografia foi feita por meio de um ditado das mesmas palavras que compõem o instrumento PERCEFAL. RESULTADOS: Foram observadas: maior acurácia perceptual-auditiva do que ortográfica; tendência de menor tempo de resposta e de menor variabilidade nos acertos perceptuais-auditivos do que nos erros; não correspondência de erros de percepção-auditiva e ortografia, já que, na percepção, o maior percentual de erros envolveu o ponto de articulação das fricativas, enquanto que, na ortografia, o maior percentual envolveu o vozeamento. CONCLUSÃO: Embora se mostrem relacionados, os desempenhos perceptual-auditivo e ortográfico não apresentam correspondência termo a termo. Portanto, na prática clínica, a atenção deve-se voltar não apenas para os aspectos que aproximam esses dois desempenhos, mas, também, para os aspectos que os diferenciam.

Aim. The purpose of this study was to provide normal values for maximum phonation time (MPT) and the s/z ratio by examining 1660 children aged 4-12 years and without vocal signs or symptoms.Methods. The technique was based on the sustained emission of the /a/ vowel and fricatives /s/ and /z/.Results. The average of the MPT in children of the different age groups was as follows: 6.09 seconds for the age group 4-6 years (males, 5.97; female, 6.21 seconds), 7.94 seconds for the age group 7-9 years (males, 8.07; females, 7.79 seconds), and 8.98 for the age group 10-12 years (males, 9.05; females, 8.92 seconds). The overall average for males was 7.78 and females 7.64 seconds. The s/z ratio was near 1.0 in most children but above 1.2 in 133 children and below 0.8 in 133 children.Conclusion. These values of MPT and s/z ratio can be used as normative in further pediatric studies.

Trata o presente estudo da produção das fricativas interdentais da língua inglesa por falantes do português brasileiro (PB), aprendizes de Inglês como língua estrangeira, (English as a Foreign Language – EFL) nos Cursos Livres de Línguas Estrangeiras mantidos pela Universidade Federal do Pará. O objetivo deste estudo é investigar as possibilidades de ocorrência de substituições para as fricativas interdentais surda e sua contraparte sonora em posições de onset e coda silábica, os resultados são analisados com base na Fonologia de Geometria de Traços (Clements e Hume, 1995). A coleta de dados foi realizada junto a um grupo de vinte e dois alunos, sendo 12 alunos do terceiro nível e 10 alunos do sétimo nível. Pretende-se fazer a representação detalhada do processo de substituição que falantes do português brasileiro (PB), aprendizes de inglês como segunda língua (ESL), realizam especificamente para os segmentos fricativos interdentais da língua inglesa em suas versões surda e sonora /Ɵ/ e /ð/, no processo de aquisição da fonologia desta língua. Diferentes tipos de segmentos foram encontrados em nossa pesquisa como resultado das substituições, quais sejam: [t],[tʃ],[d],[f] e [s] para a fricativa interdental surda /Ɵ/ e [t],[d],[s],[f],[v] e [tʃ] para a fricativa interdental sonora /ð/. Os tipos predominantes de processos observados foram: (a) Fortição, (b) Posteriorização (c) Sonorização (d) Palatalização (e) Labialização (f) Epêntese e (g) Ressilabificação. Todos resultando de um processo anterior chamado Nativização.
