The speech rate is one of the important prosodic parameters for the naturalness and intelligibility of an utterance. On the basis of the authors' definition of the relative local speech rate, the present paper describes an analysis of the effects of changes in global speech rate, syntactic constituency and lexical accent on the local speech rate, using short utterances in which these factors are systematically controlled. Preliminary results indicate that the span of changes in local speech rate is the syllable rather than mora, and also shows the interaction between these factors.
