Groove Width in Croatian Voiced and Voiceless Postalveolar Fricatives
نویسندگان
چکیده
The aim of this investigation is to use a newly available electropalatography (EPG) index to quantify groove width characteristics in Croatian postalveolar fricatives. Six normal adult speakers of Croatian produced 648 nonsense VCV sequences (V: /i/, /a/, /u/; C: //, //). Anterior groove width (AGW), posterior groove width (PGW), intraspeaker and interspeaker variability were quantified. Results show that groove width is gradually narrowing towards the front of the oral cavity. AGW is virtually unaffected by vowel context, while PGW shows less coarticulatory resistance. AGW and PGW characteristics show opposite tendencies in voiced and voiceless fricatives in that AGW is slightly wider in voiceless than in voiced fricative, while voiced fricative is produced with a wider PGW than the voiceless one. The results also show that groove width variability is very low. The importance of groove width characteristics quantification for clinical use is discussed.

The phonological voicing contrast in Czech: an EPG study of phonated and whispered fricatives
Czech represents a language with a high correlation between phonological and phonetic voicing, but the perception of the voicing contrast is supported by other phonetic correlates. We employed electropalatography (EPG) to investigate the articulatory correlates of the voicing contrast in phonated and whispered speech. Eight subjects read short sentences and VCV sequences with alveolar/postalveo...
متن کاملPharyngeal articulation in the production of voiced and voiceless fricatives.
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...
متن کاملTemporal characteristics of Greek fricatives
The present study examines the temporal characteristics of Greek fricatives as distinctive cues for their place of articulation. The effects of voicing (voiced, voiceless), speaker‟s gender (fe-male, male) and post-fricative vowel ([a], [e], [i], [o], [u]) on fricative duration are also inve-stigated. The results show that fricative duration does not distinguish fricatives in terms of pla-ce of...
متن کاملGlottal Opening and Strategies of Production of Fricatives
This work investigates the influence of the gradual opening of the glottis along its length during the production of fricatives in intervocalic contexts. Acoustic simulations reveal the existence of a transient zone in the articulatory space where the frication noise level is very sensitive to small perturbations of the glottal opening. This corresponds to the configurations where both fricatio...
متن کاملContrast and covert contrast: The phonetic development of voiceless sibilant fricatives in English and Japanese toddlers
This paper examines the acoustic characteristics of voiceless sibilant fricatives in English-and Japanese-speaking adults and the acquisition of contrasts involving these sounds in 2- and 3-year-old children. Both English and Japanese have a two-way contrast between an alveolar fricative (/s/), and a postalveolar fricative (/∫/ in English and /ɕ/ in Japanese). Acoustic analysis of the adult pro...
