Pitch and Manual Gestures

Gestures and speech parallel or complement each other semantically and pragmatically. Previous studies have postulated a similarly close correlation between intonation and gesture. This study microanalyzed the gestures of three subjects frame by frame and matched the movements with direction of pitch changes for each syllable in 90 intonation groups. The speech was analyzed using spectrographs. Coordinating direction of pitch and manual gesture movements is an option available to speakers, but it is not biologically mandated.
