Real-time intelligibility affects the realization of French word-final schwa

Résumé

Speech variation has been hypothesized to reflect both speaker-internal influences of lexical access on production and adaptive modifications to make words more intelligible to the listener. The current study considers categorical and gradient variation in the production of word-final schwa in French as explained by lexical access processes, phonological, and/or listener-oriented influences on speech production, while controlling for other factors. To that end, native French speakers completed two laboratory production tasks. In Experiment 1, speakers produced 32 monosyllabic words varying in lexical frequency in a word list production task with no listener feedback. In Experiment 2, speakers produced the same words to an interlocutor while completing a map task varying listener comprehension success across trials: in half the trials, the words are correctly perceived by the interlocutor; in half, there is misunderstanding. Results reveal that speakers are more likely to produce word final schwa when there is explicit pressure to be intelligible to the interlocutor. Also, when schwa is produced, it is longer preceding a consonant-initial word. Taken together, findings suggest that there are both phonological and clarity-oriented influences on word-final schwa realization in French.
