Résumé

An understanding of the relations between speech rate and articulatory timing is critical to developing adequate models of articulatory control. In the case of geminate consonants, not much is known about how articulatory timing varies with speech rate, nor is it known whether the form of variation is similar between singletons and geminates. We investigated how gestural timing varies with speech rate in intervocalic /m/ and /mm/ from speakers of Tashlhiyt Berber, Japanese, and Italian. We found that while the timing of closure and release is nonlinearly constrained in singletons, such constraints do not apply to geminates. A secondary finding is that speech rate has complicated, speaker-specific effects on variability in timing. Together these patterns suggest that control of articulatory timing in singleton and geminate consonants may be accomplished by distinct mechanisms, particularly at slow rates of speech.
