Phonemic Resetting Versus Postural Adjustments In The Speech Of Cochlear Implant Users: An Exploration Of Voice-Onset Time, Harlan Lane, Jane Wozniak, Melanie Matthies, Mario Svirsky, Joseph Perkell

Harlan Lane

Voice-onset time (VOT) was measured in plosive-initial syllables uttered by five cochlear implant users prior to and repeatedly at intervals after activation of their speech processors. In "short-term" experiments, the elicitation set was read after the subject's processor had been off for 24 h, then turned on, then off again. Four out of five implant users increased voiceless and/or voiced VOTc (VOT corrected for changes in syllable duration) from preimplant baselines to final recordings made 1–3 years later. Measured acoustic correlates of speech "posture" (average SPL, F0, and low-frequency spectral slope) changed concurrently. Results in the short-term study were largely …
