Speed of Pitch Change

Abstract

In an attempt to determine the response characteristics of the larynx in voluntary pitch change, five adult male subjects were instructed to execute a variety of continuous pitch changes, as rapidly as possible, within the range 90–220 Hz. For a given pitch interval, there was a marked tendency for all upward pitch change to take longer than a downward pitch change. Also, unexpectedly, there was no marked tendency for a change involving a wide pitch interval to take longer than a change involving. a smaller interval. Speculations on the physiological reasons for these relations, as well as their possible relevance to the phonology of tone and intonation, will be offered.
