Acoustic Correlates of Pathologic Voice Types

Listeners classified 49 samples of vowels /a/ and /i/ on the basis of four voice types: hoarse, breathy, strained, and normal. The vowels were analyzed acoustically for mean harmonic/noise differences in four spectral regions, average fundamental frequency, natural logarithm of fundamental frequency, and jitter. Discriminant analysis showed that classifications of voice type were made with 80% accuracy using three acoustic parameters: (a) mean harmonic/noise difference factor (1–3.5 kHz), (b) natural log of fundamental frequency, and (c) vowel type. The significance of these particular acoustic parameters for the perception and classification of voice types is discussed.

Abstract Several tools have been introduced to achieve early detection of voice disorders. Among these tools are the human factor cepstral coefficients HFCC combined with prosodic parameters, the noise-harmonic ratio (NHR), the harmonic-noise ratio (HNR), analysis of trend fluctuations (DFA) and fundamental frequency (F0). These parameters are introduced and calculated in every frame. In this work, we used a variation of HFCC called equivalent rectangular bandwidth (ERB) to study the effects of HFCC on the classification of pathological voices. Using the HTK classifiers, the classification is carried out on two pathological databases, Massachusetts Eye and Ear Infirmary (MEEI) and Saarbruecken Voice Database (SVD). To assess the performance of the system, we used sensitivity and specificity.

Implicit And Explicit

Purpose This study aims to give an integrative answer on which speech stereotypes exist toward German gay and straight men, whether and how acoustic correlates of actual and perceived sexual orientation are connected, and how this relates to masculinity/femininity. Hence, it tests speech stereotype accuracy in the context of sexual orientation. Method Twenty-five gay and 26 straight German speakers provided data for a fine-grained psychological self-assessment (e.g., masculinity/femininity) and explicit speech stereotypes. They were recorded for an extensive set of read and spontaneous speech samples using microphones and nasometry. Recordings were analyzed for a variety of acoustic parameters (e.g., fundamental frequency and nasalance). Seventy-four listeners categorized speakers as gay or straight on the basis of the same sentence. Results Most relevant explicitly expressed speech stereotypes encompass voice pitch, nasality, chromaticity, and smoothness. Demonstrating implicit stereotypes, speakers were perceived as sounding straighter, the lower their median f0, center of gravity in /s/, and mean F2. However, based on actual sexual orientation, straight men only showed lower mean F1 than gay men. Additionally, we found evidence that actual masculinity/femininity and the degree of sexual orientation were reflected in gay and straight men's speech. Conclusion Implicit and explicit speech stereotypes about gay and straight men do not contain a kernel of truth, and differences within groups are more important than differences between them.

Stress Patterns

The present study examined lexical stress patterns in Uyghur, a Turkic language. The main goal of this research was to isolate and determine which acoustic parameters provide cues to stress in Uyghur. A number of studies have investigated the phonetic correlates of lexical stress across the world's languages, with stressed syllables often longer in duration, higher in pitch, and greater in amplitude. The present study systematically investigated the acoustic cues to stress in Uyghur, examining duration, fundamental frequency, and amplitude. Three experiments were conducted: one utilizing minimal pairs in Uyghur, one examining disyllabic nouns in Uyghur that contrasted in the first syllable, and one investigating the interaction of lexical stress with Uyghur sentence intonation. The data consistently show that duration was a robust cue to stress in Uyghur, with less consistent effects for intensity. The data also clearly show that fundamental frequency was not a cue to lexical stress in Uyghur. Uyghur does not use the fundamental frequency to distinguish stressed from unstressed syllables. The results suggest that Uyghur does not pattern like a pitch-accent language (e.g. Turkish), but rather like a stress-accent language.
