| Research Abstract |
Physical constraints in our speech production mechanisms sometimes cause various barriers in speech communication, such as vocal disorder, limitation of singing expressions, and so on. Statistical voice conversion capable of flexibly converting speech sounds is a potential technology to break down these barriers by augmenting speech production beyond the physical constraints. To use this technology in speech communication, it is essential to develop a high-quality and real-time conversion algorithm. In this research project, we have developed basic technologies for a next-generation voice changer based on real-time statistical voice conversion. Moreover, we have also developed various applications using the next-generation voice changer to break down the existing barriers in speech communication.
