Speech often occurs in challenging listening environments, such as masking noise. Visual cues have been found to enhance speech intelligibility in noise. Although the facilitatory role of audiovisual integration for perception of speech has been established in native speech, it is relatively unclear whether it also holds true for speech produced by nonnative speakers. Native listeners were presented with English sentences produced by native English and native Korean speakers. The sentences were in either audio-only or audiovisual conditions. Korean speakers were rated as more accented in audiovisual than in the audio-only condition. Visual cues enhanced speech intelligibility in noise for native English speech but less so for nonnative speech. Reduced intelligibility of audiovisual nonnative speech was associated with implicit Asian-Foreign association, suggesting that listener-related factors partially influence the efficiency of audiovisual integration for perception of speech produced by nonnative speakers. / text

Para isso, partiu-se dos pressupostos da Fonologia de Uso (BYBEE, 2001, 2006, 2010), da Teoria de Exemplares (PIERREHUMBERT, 2001, 2003) e da Sociofonética (THOMAS, 2011; FOULKES; SCOBBIE; WATT, 2010). A amostra sob análise é constituída por oito informantes (quatro homens e quatro mulheres) entre 18 e 50 anos de idade e de dois níveis de escolaridade – sujeitos com até seis anos de escolaridade e sujeitos com, no mínimo, nove anos de escolaridade. A taxa de aplicação do apagamento na amostra analisada foi de 53% (N = 242) para a vogal [i], de 41% (N = 196) para a vogal [u] e de 0,8% (N = 4) para a vogal [a]. Os resultados indicaram que fatores como tipo de vogal, contexto precedente, ordem de produção e frequência lexical favorecem o apagamento, revelando a natureza predominantemente linguística do fenômeno. A única variável extralinguística que teve influência no apagamento foi a variável indivíduo. A análise acústica revelou que as vogais postônicas [i] e [u] produzidas pelos pelotenses tendem a abaixar enquanto a vogal [a] tende a elevar-se. Além disso, percebe-se uma centralização de [u], que ocupa, entre os homens, quase o mesmo espaço acústico que a vogal [a]. [ɐ], [ɪ] e [ʊ] são as vogais que representam o sistema encontrado na amostra. Com relação à duração, comparando-se os valores encontrados com os dados de Quintanilha-Azevedo (2016), percebe-se que tanto homens quanto mulheres produziram vogais mais curtas. Por fim, conclui-se que o apagamento representa o ponto final de uma trajetória que se inicia com a realização plena da vogal, passa pela redução de sua duração e pelo seu desvozeamento. / This thesis aims to analyze the variable process of deletion of the final unstressed vowels [a, i, u] by Brazilian Portuguese native speakers from the city of Pelotas, in the Southern state of Rio Grande do Sul, as noticed in words such as tarif[a] ~ tarif∅, equip[e] ~ equip∅, serviço ~ serviç∅, for instance. In order to achieve said aim, the concepts addressed by Usage-Based Phonology (BYBEE, 2001, 2006, 2010), the Exemplar Theory (PIERREHUMBERT, 2001, 2003) and Sociophonetics (THOMAS, 2011; FOULKES; SCOBBIE; WATT, 2010) were used as this research project's theoretical bases. The sample analyzed in this study consists of 8 informants (4 men and 4 women) from two different educational backgrounds (one group including subjects with up to 6 years of formal learning and the other including subjects with 9+ years of formal learning) with ages ranging from eighteen to fifty. The rate of deletion in the sample was of 53% (N = 242) for the vowel [i], of 41% (N = 196) for the vowel [u], and of 0,8% (N = 4) for the vowel [a]. The results indicate that such factors as type of vowel, preceding context, vowel production order and lexical frequency favor deletion, revealing the predominantly linguistic nature of the phenomenon. The variable "subject" was the only extralinguistic variable to influence deletion. Acoustic analysis showed that the posttonic vowels [i] and [u] produced by the subjects tend to lower as the vowel [a] tends to rise. In addition, the study also revealed a centralization of [u], which occupies among men almost the same acoustic vowel space as does the vowel [a]. Vowels [ɐ], [ɪ] and [ʊ] are representative of the system found in the sample. Regarding duration, when comparing the values included in this research project with those presented by Quintanilha-Azevedo (2016), it can be noticed that both men and women produced shorter vowels. Lastly, it was found that deletion represents the final stage of a process that begins with the production of a full-quality vowel, moves on to its reduction, and ultimately reaches the devoicing of said vowel.

The phenomenon of an ongoing sound change leads in some cases to the pronunciation of short ö becoming more like that of short u. This thesis examines the relationship between short ö and u in Uppland Swedish. The localities included in the investigation were Uppsala, Norrtälje, Östervåla and Gräsö. In particular, the thesis examines the effects of age, gender and social status on the acquisition of a pronunciation where the phonemes are produced in a similar way, and whether the change occurs earlier in some words than others. The informants on Gräsö appear to have the highest occurrence of the merger, while those in Norrtälje are best at keeping ö and u apart. In general, men have a smaller difference between ö and u than women. Three different age groups were analysed and the results show that the oldest informants have the largest difference between ö and u and the youngest informants have the smallest difference. There are no significant differences between the three social status groups, but there is a tendency for those with the lowest social status to be better at keeping the phonemes apart than those with the highest social status. 13 minimal (or near-minimal) pairs were analysed to investigate whether the phonetic context has an effect on the degree to which ö and u are becoming more similar. The study shows that the smallest phonetic difference is found for word pairs with r occurring in the preceding or following context. The largest phonetic distance was found in word pairs beginning with a vowel. The study also examined whether there is a relationship between production, perception and attitude to u-sounding ö in Uppsala. By combining the production test results with the informants’ categorisation of u and ö in the perception test, the study shows that the informants with a small phonetic distance in their own speech were better at categorising stimuli correctly than the speakers who had a larger phonetic distance between ö and u in their own speech.

Objectif : Les femmes avec œdème de Reinke (FR) sont souvent prises pour des hommes au téléphone. Ainsi, leurs voix masculines sont intéressantes pour l’étude des stéréotypes de genre dans la voix. L’objectif de cette étude est de vérifier leur plainte dans un cadre expérimental et de rechercher les paramètres acoustiques utilisés dans l’identification du genre en se basant sur leurs voix.Matériel et Méthode : Une étude d’auto-évaluation met en évidence la perception qu’ont les FR de leurs voix. Une étude de production compare les paramètres acoustiques de voyelles et de phrases produites par 10 FR avec ceux des productions de 10 femmes et de 10 hommes aux voix normales (FN et HN). Un jury naïf évalue le genre vocal des FR, FN et HN. Résultats : Les FR s’auto-évaluent comme ayant une voix masculine et une personnalité féminine. Les paramètres acoustiques qui permettent de distinguer les voix des FR sont liés à la fréquence fondamentale, à la pente spectrale, au ratio des harmoniques par rapport au bruit et à la complexité de l’enveloppe spectrale. Le jury naïf, surtout les femmes, jugent les voix des FR comme « sûrement masculines » plus souvent qu’elles ne jugent les voix des FN quelle que soit la production vocale. Conclusions : Les auditeurs et surtout les auditrices évaluent les FR comme ayant une voix « sûrement masculine » par rapport aux FN. Ce classement est corrélé à la F0 ainsi qu’à des paramètres acoustiques liés à la qualité vocale : CPP, H1H2, HNR05, HNR15 et HNR25. Ces nouvelles informations contribuent à la compréhension de la perception du genre dans la voix et pourraient guider la réhabilitation des personnes se plaignant d’ambiguïté du genre vocal. / Purpose: Women with Reinke’s edema (RW) are often identified as men over the phone. For this reason, their masculine sounding voice is interesting for the study of gender stereotypes. The study’s objective is to verify their complaint and to understand the cues used in gender identification based on their voices.Methods: We verified, through a self-evaluation study, the perception of their own voice by RW. We compared the acoustic parameters of vowels and sentences produced by 10 RW to those produced by 10 men (NM) and 10 women (NW) with normal voices in Lebanese Arabic. We conducted two perception studies for the evaluation of RW, NM and NW voices by naïve listeners. Results: RW self-evaluated their voice as being masculine and their personality as being feminine. The acoustic parameters distinguishing RW voices concern pitch, spectral slope, harmonicity of the voicing signal and complexity of the spectral envelop. Naïve listeners (especially women) rate RW voices as “surely masculine” more often than they rate NW voices even in sentences. Conclusions: Listeners (especially women) rate RW’s gender as “surely masculine” more often than NW. These incorrect gender ratings are correlated with acoustic measures of voice quality. The most contributing parameters to gender perception are: F0, CPP, H1H2, HNR05, HNR15, and HNR25. This new data contributes to the understanding of the perception of gender in voice and will guide the rehabilitation plan of patients complaining of an ambiguous voice.

Ce travail de thèse interroge le lien qui existe entre voix et genre. Le triple dispositif analytique sociophonétique, consistant à articuler données phonétiques, expérimentales et ethnographiques, a permis d’étudier comment une voix est perçue comme genrée et comment des locutrices/eurs utilisent des pratiques vocales pour indexer des identités de genre. Deux expériences dans lesquelles étaient utilisés comme stimuli des voix de synthèse et des voix resynthétisées ont permis d’observer que la fréquence fondamentale et les fréquences de résonance jouent des rôles différents dans la perception du genre. Une troisième expérience avec des voix de locutrices/eurs trans (transgenres, transsexuel-le-s) a permis de reproduire les résultats des deux expériences précédentes : en deçà d’un certain seuil de fréquence fondamentale, les voix tendent à être perçues comme « voix d’hommes » ; la perception genrée de voix produites avec des fréquences fondamentales supérieures à ce seuil est cependant largement déterminée par les fréquences de résonance.L’étude de pratiques vocales utilisées par des locutrices/eurs trans a soulevé un ensemble de questions sur le passing de genre et sur la co-indexation d’identités et de postures par la voix. Elle a aussi soulevé la question de la légitimité de chercheurs identifiés comme hommes cisgenres à réaliser ce type d’étude. Une démarche ethnographique a pu apporter des éléments de réponse à ces différentes questions. Une analyse de la littérature phonétique a finalement permis de montrer que celle-ci, à travers ses questions et hypothèses de recherche, ses axiomes, ses analyses et interprétations des données, peut véhiculer une idéologie de genre binaire et sexiste. / The aim of this dissertation is to investigate the relationship between voice and gender. Phonetic, experimental and ethnographic data have been used to study how the voice is perceived as gendered and how speakers use vocal practices to index gender identities. Two experiments with synthetized and resynthesized voices have shown that fundamental frequency and resonance frequencies play different roles in the perception of gender. The results of these experiments could be reproduced in a third experiment with voices of transgender speakers: under a certain fundamental frequency threshold, voices tend to be perceived as “male voices”; but above this threshold, resonance frequencies define if the voice is perceived as “female voice” or “male voice”. The study of the vocal practices of transgender speakers raised questions about gender passing, and about the indexical link between identities, stances and voice. It also raised the question of the legitimacy of researchers that are identified as cisgender males to do research on trans speaker voices. These different questions could be addressed through ethnographic data. Finally, an analysis of the phonetic literature showed that the research questions and hypotheses, the axioms, the analyses and interpretations of data one can find in phonetic studies can be a vehicle for a sexist and binary gender ideology.

This thesis provides a comparative analysis of vowel quality in South African English (SAE) using the following data: firstly, the existing impressionistic literature on SAE and other relevant accents of English, the former of which is subject to a critical review; secondly, acoustic data from a similar range of accents, including new SAE data, collected and instrumentally analyzed specifically for the purposes of this research. These various data are used to position, on both a descriptive and theoretical level, the SAE vowel system. In addition, and in the service of providing a careful reconstruction of the linguistic history of this variety, it offers a three-stage koin´eization model which helps, in many respects, to illuminate the respective roles played by endogenous and exogenous factors in SAE’s development. More generally, the analysis is focussed on rendering explicit the extent to which the synchronic status and diachronic development of SAE more generally, and SAE vowel quality more particularly, provides support for a number of descriptive and theoretical frameworks, including those provided in Labov (1994), Torgersen and Kerswill (2004), Trudgill (2004) and Schneider (2003; 2007). With respect to these frameworks, and based on the results of the analysis, it proposes an extension to Schneider’s (2007) Dynamic Model, shows Trudgill’s (2004) model of new-dialect formation to be inadequate in accounting for some of the SAE data, provides evidence that SAE is a possibly imminent but ‘conservative’ member of Torgersen and Kerswill’s (2004) SECS-Shift and uses SAE data to question the applicability of the SECS-Shift to FOOT-Fronting. Furthermore, this thesis provides evidence that SAE has undergone an indexicallydriven arrestment of the Diphthong and Southern Shifts and a subsequent and related diffusion of GenSAE values at the expense of BrSAE ones. Similarly, it shows that SAE’s possible participation in the SECS-Shift constitutes an effective chain-shift reversal ‘from above’. It stresses that, in order to understand such phenomena, recourse needs to be made to a theory of indexicality that takes into account the unique sociohistorical development of SAE and its speakers. Lastly, the adoption of the three-stage koin´eization model mentioned above highlights the merits of considering both endogenous and exogenous factors in the historical reconstruction of new-dialect formation and, for research into SAE in particular, strengthens the case for further investigation into the possible effects of 19th-century Afrikaans/Dutch, Yiddish and north-of-English dialects on the formation of modern SAE. / Thesis (Ph.D. (English))--North-West University, Potchefstroom Campus, 2009.
