This paper discusses some ideas for the requirements and methods of conversational speech synthesis, based on experience gained from the collection and analysis of a very large corpus of conversational speech in a variety of real-life everyday contexts. It shows that because variation in voice quality plays a significant part in the transmission of interpersonal and affect-related social information, this feature should be given priority in future speech synthesis research. Several solutions to this problem are proposed.
