Devoicing Measures of European Portuguese Fricatives
نویسندگان
چکیده
This paper presents a study of devoicing of European Portuguese fricatives. Two devoicing criteria (a manual criterion and a criterion based on the ratio of variances of the laryngograph signal during the VF transition and during the fricative) were used to classify the examples into two or three categories. The results of the automatic and manual measures of devoicing are compared, and an explanation for observed misclassifications is presented. Devoicing occurs extensively in Portuguese; results are compared to those for English.

A parametric study of the spectral characteristics of European Portuguese fricatives
Studies of Portuguese phonetics and phonology indicate that fricatives are central to some interesting features of the language, yet studies of Portuguese fricatives have been few and limited. In this study, Portuguese fricatives were analyzed in ways designed to enhance our description of the language and to increase our understanding of the production of fricatives. Corpora of Portuguese word...
متن کاملDevoicing of Phonologically Voiced Obstruents: Is European Portuguese Different from Other Romance Languages?
This paper presents results for voicing maintenance during European Portuguese (EP) stop and fricative production. Results showed that EP presented a high amount of devoicing for all phonologically voiced stops and fricatives. This is in contrast to classical literature reporting high voicing maintenance during stop closure for Romance languages, but confirms our preliminary results from previo...
متن کاملAcoustic analysis of a speech corpus of european portuguese fricative consonants
The study of Portuguese fricatives is a complex problem, which has not been explored fully. As part of a larger study of the acoustic properties of Portuguese fricatives, corpora of Portuguese words containing /f, v, s, z, A, O/, nonsense words with Portuguese phonology, and sustained Portuguese fricatives have been recorded and analysed. Results show that more than half of the voiced fricative...
متن کاملProsodic strengthening of German fricatives in duration and assimilatory devoicing
This study addressed prosodic effects on the duration of and amount of glottal vibration in German word-initial fricatives /f, v, z/ in assimilatory and non-assimilatory devoicing contexts. Fricatives following /=/ (non-assimilation context) were longer and were produced with less glottal vibration after higher prosodic boundaries, reflecting domaininitial prosodic strengthening. After /t/ (ass...
متن کاملThe Devoicing of Fricatives in Southern British English
In connection with the phonological distinction between voiced and voiceless sounds in languages, it can be observed that voiced sounds are relatively frequently devoiced, i.e. they are realized phonetically with little or no vocal fold vibration. This study investigated the devoicing of /v/ and /z/ in Standard Southern British English (SSBE) by means of a production experiment in which vocal f...
