this article addresses the perceptual correlates of compensatory lengthening in persian. in a perception experiment, duration, spectral tilt measurements h1-h2 and h1-f1 and f0 were varied in several steps based on the results from a production experiment (sadeghi, 2007). subjects were asked to identify the tokens involving vowel length. results revealed that duration is the most reliable perce...

The aim of this study is to evaluate the role of spectral tilt, alongside the traditionally looked at frequencies of the first two formants, in describing the acoustic characteristics of pharyngealisation in Jordanian and Moroccan Arabic. Twenty male speakers (10 per dialect) produced vowels in each dialect preceded by /d dʕ/. Normalised spectral tilt results show an overall lowered values for ...

This acoustical and Electroglottography (EGG) study investigates the effect of coda deletion and co-articulatory phasing on vowels and final coda stops, [p t k ʔ], in Taiwan Min checked tones 3 and 5 syllables. Vowel duration, f0, spectral tilt (H1*-A3*), cepstral peak prominence (CPP) and glottal contact quotient (CQ_H) were analyzed. Compensatory lengthening, f0 lowering and increasing period...

Tools and methods for the calculation of acoustical, musical and physiological criteria using a sound file from the singing voice are presented, as well as tools for the automation of the time-dependant calculation processes used for analysis and statistics. The difference between recordings in an unechoic chamber and a simulated condition with reverberation is calculated using a soundfile reco...

acoustic analysis of sounds produced during speech provides significant information about the physiology of larynx and vocal tract. the analysis of voice power spectrum is a fundamental sensitive method of acoustic assessment that provides valuable information about the voice source and characteristics of vocal tract resonance cavities. the changes in long-term average spectrum (ltas) spectral ...

The effects of age, sex, and vocal tract configuration on the glottal excitation signal in speech are only partially understood, yet understanding these effects is important for both recognition and synthesis of speech as well as for medical purposes. In this paper, three acoustic measures related to the voice source are analyzed for five vowels from 3145 CVC utterances spoken by 335 talkers (8...

This study explored the voice quality of Taiwan Min checked tones 5 and 3 produced by speakers of varying ages from northern, central and southern Taiwan with Zhanzhou, Quanzhou and mixed accents. Comparison between spectral tilt (difference between H1*-H2* amplitudes) and closed quotients of the glottal wave form showed that checked tones with creaky / tense voice quality were distinguished fr...

This exploratory acoustic study focused on the relationship between laryngeal constriction and vowel quality in the vocalizations of infants aged 0-12 months learning Bai, which employs laryngeal constriction distinctively in its register tone system, and English, which uses laryngeal constriction only paralinguistically. Spectral tilt (H2-H1) measurements of front, neutral, and open vowels sho...

Acoustic cues related to the voice source, including harmonic structure and spectral tilt, were examined for relevance to prosodic boundary detection. The measurements considered here comprise five categories: duration, pitch, harmonic structure, spectral tilt, and amplitude. Distributions of the measurements and statistical analysis show that the measurements may be used to differentiate betwe...

Acoustic analysis of voice quality proves useful in the objective assessment of voice disorders and for motivating new components for use in improving voice synthesis. A commonly used quantitative spectral index is the harmonicsto-noise ratio (HNR), which gives gross information regarding speech signal periodicity. However, as the measure is sensitive to all forms of waveform aperiodicities (no...
