Acoustic evidence of articulatory adjustments to sustain voicing during voiced stops
نویسنده
چکیده
The present study seeks to provide acoustic evidence of articulatory adjustments to initiate and sustain voicing during stops. First, using aerodynamic and acoustic data, it examines variations in the amplitude of voicing in phraseinitial voiced stops in Spanish and English and relates these variations to articulatory adjustments to preserve a low oral pressure and voicing. Second, a correlation is sought between oral pressure and voicing amplitude during stop closure. The correlation is significant for all Spanish (4) and English (2) speakers; as oral pressure rises, voicing amplitude decreases. The study concludes that articulatory adjustments to keep a low intraoral pressure for voicing may be inferred from the time course of voicing amplitude during the stop closure. Significant differences between prevoiced stops in the two languages are found, with overall higher values for oral pressure and lower values for voicing amplitude in English than in Spanish.

Articulatory Adjustments in Initial Voiced Stops in Spanish, French and English
This work reports cross-language differences in the voicing of initial voiced stops, and in the use of active maneuvers to achieve closure voicing, using multiparametric aerodynamic data. Oral pressure, oral and nasal flow, and acoustic data were obtained for utterance-initial /b d p t m/ for 10 speakers of Spanish, 6 speakers of French and 5 speakers of English. Voiced stops were classified as...
متن کاملArticulatory Conflict and Laryngeal Height
In cases of articulatory conflict, gestures involved in preserving phonemic distinctiveness are generally favored over gestures that do not. Here, an apparent exception to the phonemic distinctiveness preservation hypothesis is shown to in fact conform to it: in English, the larynx is lowered before voiced stops to maintain voicing distinctiveness, but the larynx is raised during high vowels, a...
متن کاملArticulatory overlap as a function of voicing in French and German consonant clusters.
The effects of laryngeal specification on the timing of supra-laryngeal articulations have so far received little attention. Previous research has shown that German-but not French-mixed-voicing clusters are produced with less articulatory overlap than phonologically fully voiced clusters. Articulatory and acoustic data of labial and velar stops as simple onsets and in stop + /l/ clusters are ex...
متن کاملDevoicing of Word-initial Stops: a Consequence of the following Vowel?
The aim of the current study is to investigate the contextual conditions of devoicing of phonologically voiced stops (bilabial and velar). Articulatory and acoustic data from four male speakers were recorded by means of EMMA and EPG. Devoicing was observed more frequently for the velar stops than for the bilabials. The highest occurrence of devoicing was observed when the voiced stop was follow...
متن کاملLip kinematics for /p/ and /b/ production during whispered and voiced speech.
In the absence of voicing, the discrimination of "voiced" and "voiceless" stop consonants in whispered speech relies on such acoustic cues as burst duration and amplitude, and formant transition characteristics. The articulatory processes that generate these features of whispered speech remain speculative. This preliminary investigation examines the articulatory kinematics differences between w...
