Patent number: 7627470Abstract: A speaking period required for a voice recognition processing is detected with a simple and robust approach. A speaking period is detected based on an EMG generated when a speaker speaks. A large amplitude is observed in an EMG as muscular activity is caused when a speaker speaks. By observing this, a speaking period can be detected. The EMG can be measured from the speaker's skin via electrodes provided on a mobile-type terminal. Since a mobile-type terminal is usually pressed to the skin for use, affinity between this use form and the present invention is very high.Type: GrantFiled: September 14, 2004Date of Patent: December 1, 2009Assignee: NTT DoCoMo, Inc.Inventors: Hiroyuki Manabe, Akira Hiraiwa, Yumiko Hiraiwa, legal representative, Kouki Hayashi, Toshiaki Sugimura, Toshio Miki

Patent number: 7480616Abstract: Information relating to an amount of muscle activity is extracted from a myo-electrical signal by activity amount information extraction means, and information recognition is performed by activity amount information recognition means using the information relating to the amount of muscle activity of a speaker. There is a prescribed correspondence relationship between the amount of muscle activity of a speaker and a phoneme uttered by a speaker, so the content of an utterance can be recognized with a high recognition rate by information recognition using information relating to an amount of muscle activity.Type: GrantFiled: February 27, 2003Date of Patent: January 20, 2009Assignee: NTT DoCoMo, Inc.Inventors: Hiroyuki Manabe, Akira Hiraiwa, Toshiaki Sugimura

Patent number: 7216078Abstract: The myo-electric information of the user is transmitted to the data center, learning with a high computation load for generating recognition parameters required for recognizing the utterance content based on the myo-electric information is performed, not by the mobile communication terminal, but by the data center. By this, compared with the case when learning is performed in the mobile communication terminal which has stricter limitations on processing speed and memory than a stationary type computer, efficient learning in a shorter time becomes possible. Since the recognition parameters acquired at the data center are transmitted to the mobile communication terminal, hereafter utterance content recognition can be appropriately performed by the recognition parameters matching the user only by the mobile communication terminal, without the mobile communication terminal transmitting/receiving information with a learning device.Type: GrantFiled: February 19, 2003Date of Patent: May 8, 2007Assignee: NTT DoCoMo, Inc.Inventors: Hiroyuki Manabe, Akira Hiraiwa, Toshiaki Sugimura
