Voice quality description from a phonetic perspective: Supralaryngeal and muscular tension settings
نویسندگان
چکیده
This study aims at investigating the acoustic correlates of supralaryngeal and muscular tension voice quality settings (VQS). Speech samples from 40 speakers were perceptually analyzed by means of the Vocal Profile Analysis Scheme (VPAS). Acoustic analysis comprised formant frequency (F1, F2 and F3) and intensity measurements (I1, I2 and I3) of seven Brazilian Portuguese vowels. Multivariate statistical analysis was performed to take into account the discriminant capability of the acoustic measures to detect VQS as well as influences from gender, age and vowel type. The results have shown the discriminant power of formant measures to predict neutral and non-neutral VQS: I1, F3, I3 and I2 correlated with supralaryngeal VQS and F1 and F1, I2 and I3 with muscular tension.The canonical correlation analysis of VQS, formant measures and gender variables have shown that neutral VQS grouped with F1 and F2 and non-neutral VQS grouped with F3, I1, I2 and I3.

Voice qualities and speech expressiveness
The objective of this work is to investigate correlations between the use of settings of vocal qualities and the expression of acted emotions and attitudes in speech. For the description of voice qualities, the phonetic model of description of voice quality settings developed by [1] was used. The corpus is constituted by the poem "I-Juca Pirama", interpreted by a professional actor. The percept...

In forensic voice comparison, there is increasing focus on the integration of automatic and phonetic methods to improve the validity and reliability of voice evidence to the courts. In line with this, we present a comparison of long-term measures of the speech signal to assess the extent to which they capture complementary speaker-specific information. Likelihood ratiobased testing was conducte...

This paper studies high registers of heavy metal singing based on the voice profile analysis scheme (VPAS) and acoustic correlates. The f0 range varied from 366 to 666 Hz. The application of VPAS for singing is unique in the phonetic literature. Two professional and two amateur singers sang Iron Maiden’s Aces High with instrumental playback through headphones. Two very high-register excerpts we...
متن کاملEvaluating speech samples designed for the Voice Profile Analysis Scheme for Brazilian Portuguese (BP-VPAS)
The present study aims at evaluating a corpus designed for voice quality settings analysis (Laver, 1980). It addresses the role of keyspeech segments for the identification of voice quality settings. The corpus, recorded by 60 speakers, contained repetitions of 10 keyspeech sentences, and semi-spontaneous speech samples. These samples were evaluated by two expert subjects according to the BP-VP...
