Abstract This study uses acoustic energy measures for /b, d, g/ after /f, s, ∫, l, r/ in Catalan in order to test whether postconsonantal voiced stop lenition is ruled by minimization of articulatory effort, acoustico-perceptual continuity of an ongoing prosodic constituent or some other principle of articulatory organization. Data for eight speakers reveal that lenition is more prone to operat...

This study investigates the Voice Onset Time (VOT) of stop consonant production in six bilingual English-Arabic children in order to examine whether bilingual children possess one unitary or two separate linguistic systems. A total of six English-Arabic bilingual children participated ages 5 to 10. English and Arabic stop consonants followed by a vowel /a/ made by bilingual children were measur...

The purpose of this study was two fold: i) to evaluate the voicing feature and ii) to determine the correlation between perceptual and acoustic characteristics of French voiced and voiceless stop consonants produced by 10 patients after supracricoïd partial laryngectomy (SCPL). In SCPL patients’ speech, voice is produced by a neoglottis located at approximately 3 cm above the removed vocal fold...

In this paper we propose excitation-based features for extracting information about the manner of articulation for stop consonants. The excitation-based features are derived from very low frequency information in the signal and also from the normalized error computed from the linear prediction residual. The proposed zero-frequency filtered signal brings out the region of glottal activity during...

The production of voice-onset time (VOT) was studied in a group of Spanishand English-learning subjects at 1 and 2 years of age. Voiceonset time of initial stop consonants from canonical utterances was measured oscillographically. At one year no significant difference in VOT production was found between Spanish and English learners at any place of articulation. Mean VOT values for infants fell ...
