What is the Baseline for the Perception of Phoneme Duration?
Changes of speaking rate affect both the total duration of an utterance and the relative durations of its component phonemes.

Zusammenfassung: | Changes of speaking rate affect both the total duration of an utterance and the relative durations of its component phonemes. An experiment was performed to see how these variables affect the duration that a phoneme should have, if it is to sound natural in context. Incremental and decremental just noticeable differences were measured for the stop closure of a /p/ embedded in a sentence spoken normally and spoken fast. The measurements were then repeated with the playback speed of the normally spoken stimuli increased by 8%, 16%, and 22%, and with that of the fast-spoken stimuli decreased by the same amounts. The optimal relative duration of the stop closure did not appear to change when the playback speed was changed, but was different for the normal- and fast-spoken versions when their total durations were equated. Some implications of this result are discussed. [This research was supported in part by the Science Research Council (U.K.), and in part by an NINDB grant.] |
