Problems solved by technology

At present, the sound source localization technology in the robot system is still limited to the localization of the sound source with high energy value, and it does not locate the voice spoken by the user. Therefore, the sound source localization process is easily disturbed by the environmental noise. After the judgment is wrong, there will be left and right swinging phenomenon, and it will also affect the beam alignment of the microphone array to the speaking user, reduce the signal-to-noise ratio of the microphone array pickup, and have a certain impact on the user experience of speech recognition

Abstract

The invention discloses a robot voice addressed rotation system and a method thereof. The robot voice addressed rotation system comprises a voice activity detection unit used for detecting a received voice signal and judging whether a user sends out a voice signal or not, a voice addressed unit used for calculating the addressing angle of the voice signal, and a voice addressed rotation unit used for driving a robot to turn to the direction of the voice source of the voice signal according to the addressing angle of the voice signal. In this way, the voice recognition accuracy can be improved. Meanwhile, the voice recognition accuracy and the signal-to-noise ratio are improved. Based on the robot voice addressed rotation method, the voice signal sent from the user can be accurately and effectively obtained. Therefore, the signal-to-noise ratio and the voice recognition accuracy are improved.

Description

technical field [0001] The invention relates to the field of audio recognition, in particular to a robot voice direction finding and turning system and method. Background technique [0002] Sound source localization technology is a technology that uses acoustic and electronic devices to receive target sound field information to determine the position of the target sound source. At present, the sound source localization technology in the robot system is still limited to the localization of the sound source with high energy value, and it does not locate the voice spoken by the user. Therefore, the sound source localization process is easily disturbed by the environmental noise. After the judgment is wrong, there will be a left-right swinging phenomenon, and it will also affect the alignment of the microphone array beam to the speaking user, reduce the signal-to-noise ratio of the microphone array pickup, and have a certain impact on the user experience of speech recognition. ...
