Prénasalisation des plosives voisées initiales dans la parole apraxique : une étude aérodynamique pilote

Abstract : This preliminary study examines nasal leak during the production of Spanish word-initial stops in an apraxic speaker in order to determine if this motor adjustment is used as a compensatory mechanism aimed at facilitating the initiation of voicing in stops. The results show that /b d g / correctly identified as ‘voiced’ exhibit significantly larger amounts of nasal airflow during the stop closure than those identified as ‘voiceless’ ([-voice] and devoiced stops). These results suggest that prenasalization may be an adaptive mechanism to overcome the frequent devoicing errors of apraxia. Nasal leak during voiced /b d g/ –but not their voiceless counterparts– is significantly larger (i) in phrase initial vs non-phrase initial position, and (ii) when followed by tautosyllabic nasal (e.g. banco). On the other hand, no effect of word frequency on the occurrence of nasal leak in voiced stops was found suggesting that this compensatory strategy takes place at the phonetic level of encoding.
