Abstract

The embodiment of the invention provides a voice signal recognizing method and device. The method includes the steps of obtaining space audio signals in a designated space, separating continuous voicesignals in multiple sound source directions and corresponding directive marking signals out of the space audio signals according to the space audio signals, combining the continuous voice signals inthe sound source directions with the corresponding directive marking signals in one of the sound source directions, and generating voice activating and detecting signals in the sound source direction.In the method, since the voice activating and detecting signals in one sound source direction are obtained by combining the continuous voice signals in the sound source direction with the directive marking signals, the voice activating and detecting signals have directivity, and therefore the interference of the continuous voice signals in other sound source directions to the voice activating anddetecting signals in the sound source direction can be reduced.

Description

technical field [0001] The present application relates to the technical field of signal processing, in particular to a speech signal recognition method and a speech signal recognition device. Background technique [0002] In a multi-person voice interaction scenario, Voice Activity Detection (VAD) is usually used to monitor individual voices. For example, in a conference, voice activation detection can be used to monitor the voices of each speaker, and then recognize and record the voice, so as to obtain a conference record for each speaker. For another example, in car driving, the vehicle-mounted terminal can recognize and listen to the driver's voice through voice activation detection, then recognize the driver's voice, and perform the operation required by the user according to the driver's voice. For example, wake up the car terminal, play music, answer calls, etc. [0003] However, the main problem in the current voice activation detection is that it is impossible to ...
