The age at which children master adult-like voiced stops can generally be predicted by voice onset time (VOT): stops with optional short lag are early, those with obligatory lead are late. However, Japanese voiced stops are late despite having a short lag variant, whereas Greek voiced stops are early despite having consistent voicing lead. This cross-sectional study examines the acoustics of wo...

A structural magnetic resonance imaging study has revealed that pharyngeal articulation varies considerably with voicing during the production of English fricatives. In a study of four speakers of American English, pharyngeal volume was generally found to be greater during the production of sustained voiced fricatives, compared to voiceless equivalents. Though pharyngeal expansion is expected f...

Dichotic listening experiments show a right-ear advantage (REA), reflecting a left-hemisphere (LH) dominance. However, we found a decrease in REA when the initial stop consonants of two simultaneous French CVC words differed in voicing rather than place of articulation (Experiment 1). This result suggests that the right hemisphere (RH) is more involved in voicing than in place processing. The v...

In this paper, a voiced-unvoiced measure is used as acoustic feature for continuous speech recognition. The voiced-unvoiced measure was combined with the standard Mel Frequency Cepstral Coefficients (MFCC) using linear discriminant analysis (LDA) to choose the most relevant features. Experiments were performed on the SieTill (German digit strings recorded over telephone line) and on the SPINE (...

--English abstract This paper presents the treatment of the Old Chinese *sprefix in the Baxter-Sagart system of Old Chinese reconstruction. The main functions of the prefix are to increase the valency of verbs and to derive oblique deverbal nouns. The phonetic evolutions to Middle Chinese of *swith different kinds of OC root initials are discussed. Two salient features of the proposed system ar...

This study investigates the extent of voicing in the voiced plosives /b, d/ across a range of phonetic contexts in Irish English. Spectrographic and waveform analysis showed that /b, d/ were almost always voiceless sentence-initially, substantially devoiced sentence-finally, and varied considerably sentence-medially. Further analysis of sentencemedial position found that if the plosive was part...

Phonetic detail of voiced and unvoiced fricatives was examined using speech analysis tools. Outputs of eight f0 trackers were combined to give reliable voicing and f0 values. Log energy andMel frequency cepstral features were used to train a Gaussian classifier that objectively labeled speech frames for frication. Duration statistics were derived from the voicing and frication labels for distin...

The phonological status of voiced stops in Modern Greek (MG) remains unclear. Research shows that listeners typically discriminate native phonological contrasts without difficulty. We report MG listeners show excellent discrimination of MG bilabial [p]-[b] and coronal [t]-[d] stop voicing contrasts, significantly better than their discrimination of nonnative Australian English (AE) [p]-[p] and ...
