Abstract In order to improve the naturalness of TTS speech so as to represent the cadence of natural speech, it is necessary to have a study on the pitch of spontaneous speech. Based on the 973 telephone corpus, the pitch ranges and pitch registers of 1084 intonation phrases are analyzed. It is found that intonation phrases can be classified according to their ranges and registers, and this is related to their positions in dialogue exchange. Compared with read speech, the pitch patterns in dialogue are more variable.
