Example Embodiment

[0065] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0066] At present, with the popularity of voice recognition technology, more and more smart devices have the function of voice wake-up. When the user inputs the wake-up voice into the smart device, the smart device will be woken up and then respond to the user, such as "where are you?" , "Okay" and other response words, but because the frequency domain of the response words sent by the smart device is similar to the frequency of the voice command iss...

Abstract

The invention relates to the technical field of voice signal processing, particularly to a voice signal processing method and device. The method comprises the steps: obtaining a microphone signal, wherein the microphone signal at least comprises an answering word receiving signal and a wake-up sound source signal; generating a wave beam of a wake-up sound source according to the microphone signal,the microphone array and a preset wave beam number; determining the gain value of the microphone signal according to the microphone signal and a preset reference signal, wherein the reference signalat least comprises an answering word sending signal; and according to the wave beam and the gain value, identifying the wake-up sound source signal from the microphone signal, so that the identification rate of the intelligent device for the user voice instruction can be improved.

Description

technical field [0001] The present application relates to the technical field of voice signal processing, in particular to a voice signal processing method and device. Background technique [0002] When the user enters the wake-up voice into the smart device, the smart device will issue a response word such as "okay". However, since the frequency of the response word issued by the smart device is similar to the frequency of the voice command issued by the user after waking up, therefore, The answer word will be mixed with the user's voice command, causing the problem of difficult recognition. [0003] In the prior art, it is possible to require the user to input voice instructions into the smart device after receiving the answer word, so that the smart device can use white noise to replace the answer word, but this method limits the user's interaction method, When the user does not interact in a standard way, there will be a problem that the command cannot be recognized, wh...
