The local speech rate is one of the important prosodic parameters
for representing both linguistic and paralinguistic information.
The present paper presents a command-response model for the
process of speech rate control, and applies it to the analysis of the
effects of emphasis on the local speech rate in English utterances.
It shows that the local speech rate as a function of time can be
approximated by the smoothed response of a second-order linear
system for speech rate control to a set of underlying commands,
whose timings and amplitudes serve as quantitative parameters
for representing paralinguistic information. Together with the
command-response model for F0 contour generation, it provides
a unified approach to the quantitative analysis of paralinguistic
information in prosody.
