Audio and speech signal processing for capturing and recognition of human conversations
The aim of the research is to realize a computer that can understand natural human-to-human conversations in our daily lives. It requires us to develop technologies to recognize speech with a casual speaking style even in the presence of various types of interfering sounds.
