| Research Abstract |
The accuracy of sound source localization, tracking, separation, and separated speech recognition is improved for robot audition. These improvements enable that a robot recognizes speech while the robot is moving and is gesturing, such as active audition. Restriction on robot's motion is reduced for active audition. A robot can close to a target sound source to improve signal-to-noise ratio. A robot can move to the best place for making angle between multiple sound sources wider. The improved system preserves speech recognition accuracy from noise of robot motion, when a robot's body doesn' t locates between sound source and microphone.
