Abstract: With the theory of the gender stereotype, speech as one of the important cue to gender, studies on CASA（computers as social actors）which already have a developed system of variable, design and process，have the conclusion that human will response to computer as social response, especially having gender stereotype to computer in the human-machine interaction. But there still is somewhere incomplete, such as the naturalness of TTS（text-to-speech）, using graph character as the cue, and using different task gender, etc. Finally, the promising direction to psychology, especially to the social psychology in e-time, and prospect of research are put forward in this paper.

Key words: CASA, TTS, stereotype, gender, speech
