This paper describes the investigation of manipulating positions in a speech pitch when lengthening or shortening the pitch period, that is, lowering or raising fundamental frequency of speech. The experimental results revealed that the preferable positions were at the first half of the pitch period for pitch shortening, and at the second half of it for pitch lengthening. The findings are expected to improve the quality of speech synthesis on pitch modulation.
