Abstract

The invention discloses a method for azimuth estimation. The method comprises the steps that multi-channel sampling signals are acquired and buffered; wake-up word detection is performed on each sampling signal of the multi-channel sampling signals, and a wake-up word detection score of each sampling signal is determined; if it is determined that a wake-up word exists according to the wake-up worddetection score of each sampling signal, spatial spectrum estimation is performed on the buffered multi-channel sampling signals to obtain a spatial spectrum estimation result, and the wake-up word is included in a target speech; and the azimuth of the target speech is determined according to the spatial spectrum estimation result and the highest wake-up word detection score. According to the method for azimuth estimation, the accuracy of azimuth estimation in the process of speech interaction is improved by using the wake-up words to assist in estimation of the azimuth of the target speech.

Description

technical field [0001] The present application relates to the technical field of speech processing, and in particular to a method, device and computer-readable storage medium for azimuth estimation. Background technique [0002] With the popularity of smart speakers and their derivatives, voice interaction between humans and machines, especially far-field voice interaction, has gradually become an important research direction. In the field of voice interaction, far-field voice interaction usually refers to a distance greater than 1 meter. Voice interaction between man and machine is considered to be the most important user traffic entry in the future. Therefore, both Internet platforms and content service providers attach great importance to the exploration and innovation of speech recognition interfaces. [0003] At present, voice interactive smart devices in the field of consumer electronics are mainly smart speakers, smart TVs or TV boxes with voice control functions an...
