Third International Conference on Spoken Language Processing (ICSLP 94)
At the word and phrase levels the segment duration is found to vary depending on the position in the word and in the phrase. The greatest positional effect is the phenomenon of final lengthening that appears to be of considerable generality as a phonetic phenomenon. In this investigation the segment duration is studied at different speech rates and with focus assignment systematically varied along the sentences. The subjects mimicked the prosodic pattern of the utterances by using reiterant speech. From the different utterances an "out-of-focus-utterance" was constructed by extracting the nonsense words not being in focus position. In most of these "out-of-focus-utterances" there was only a slight tendency to a final lengthening effect and in some utterances there was no final lengthening at all. This finding is contradictory to earlier obtained results for Swedish.
