| Abstract(in English) | We found a new quiet speech media, Non-Audible Murmur (NAM),and a new blind source separation algorithm, SIMO-ICA. These two inventions can enlarge the speech communication areas to further quiet and noisy environments, and for young and aged people including speech or hearing handicapped people. NAM is an extremely small voice, which is audible only for a speaker himself but inaudible for a nearby listener. NAM and a NAM microphone make it possible to communicate in the quiet environment, which is called a quiet telephone. NAM is also applied to speech recognition, which is called quiet speech recognition. NAM is also applied to speech handicapped aid using our voice conversion technique. SIMO ICA has the blind source separation (BSS) capability without distortion by the single-input multiple-output constraint. SIMO-ICA realizes hands-free communication in noisy environments. In order to implement realtime communication, we combined SIMO ICA with the binary masking successfully. We have been operating speech guidance systems in the real environments more than five years, based on large vocabulary speech recognition program (Julius). Takemaru-kun agent based speech guidance system has been used in Ikoma city north communication center. Takemaru-kun is positively accepted by Ikoma citizen, especially children. We have been also operating two types of speech guidance system in the noisy environment at the nearby railway station. They are a robot type (Kita-robo) and an agent type (Kita-chan). These two speech guidance systems are accepted by the railway company and wide range of users. We combine successfully BSS with Kita-robo in the realistic robot dialog research room to show the reality of the hands-free speech dialog system. |
