State-of-the-art text-to-speech synthesis is capable of synthesizing speech that is nearly equivalent to that of humans, and is already in use in smart speakers. On the other hand, technologies that enable flexible processing of the same text according to the situation are in demand mainly in the area of content production. As a new direction in speech synthesis research, this research aims to develop technology that allows a computer to collaborate with a user as if it were a craftsman and assist the user’s speech design. In collaboration with the field of psychology, we will identify psychological parameters for voice control suitable for text-to-speech synthesis and voice quality conversion. The aim is to systematize a series of techniques for fine-tuning the user’s rough design and synthesizing natural sound as “Bespoke Speech Design”.
