Embodiment 1

[0031] The embodiment of this application provides a method for waking up an intelligent voice device. In the first embodiment of the method for waking up an intelligent voice device of this application, refer to figure 1 , the smart voice device wake-up method includes:

[0032] Step S10, intercepting a speech signal of a fixed length from the received complete vocal signal to obtain the intercepted vocal signal, and using the complete vocal signal as the vocal signal to be detected;

[0033] Step S20: Gain the intercepted vocal signal according to the preset microphone gain to obtain the intercepted vocal signal with gain;

[0034] Step S30, judging whether the gain-intercepted vocal signal meets the amplitude requirement of the device wake-up signal;

[0035] Step S40, if not satisfied, adjust the preset microphone gain, and return to the execution step: according to the preset microphone gain, gain the intercepted vocal signal to obtain the gain intercepted vocal signal; ...

Embodiment 2

[0071] Further, refer to figure 2 , based on the first embodiment of the present application, in another embodiment of the present application, for the content that is the same as or similar to that of the first embodiment above, you can refer to the introduction above, and will not repeat them hereafter. On this basis, the step of adjusting the preset microphone gain includes:

[0072] Step S41, according to the signal amplitude of the human voice signal intercepted by the gain, it is judged whether the human voice signal is truncated by the gain, and the truncation judgment result is obtained;

[0073] Specifically, it is judged whether the signal amplitude of the gain intercepted human voice signal is greater than the preset signal amplitude threshold, and if the signal amplitude of the gain intercepted human voice signal is greater than the preset signal amplitude threshold, then it is determined that the gain intercept The human voice signal is truncated, and the trunca...

Embodiment 3

[0088] The embodiment of the present application also provides a device for waking up an intelligent voice device. The device for waking up an intelligent voice device is applied to a device for waking up an intelligent voice device. The device for waking up an intelligent voice device includes:

[0089] A signal interception module, configured to intercept a voice signal of a fixed length from the received complete vocal signal to obtain the intercepted vocal signal, and use the complete vocal signal as the vocal signal to be detected;

[0090] The first gain module is used to gain the intercepted vocal signal according to the preset microphone gain to obtain the intercepted vocal signal with gain;

[0091] An amplitude judging module, configured to judge whether the gain intercepted human voice signal meets the equipment wake-up signal amplitude requirement;

[0092] The gain adjustment module is used to adjust the preset microphone gain if not satisfied, and return to the e...

Abstract

The invention discloses an intelligent voice equipment awakening method and device, electronic equipment and a readable storage medium. The intelligent voice equipment awakening method comprises the following steps: intercepting a voice signal with a fixed length from a received complete human voice signal so as to obtain an intercepted human voice signal, and taking the complete human voice signal as a to-be-detected human voice signal; gaining the intercepted human voice signal according to a preset microphone gain so as to obtain a gained intercepted human voice signal; judging whether the gained intercepted human voice signal meets an equipment awakening signal amplitude requirement or not; if not, adjusting the preset microphone gain, and returning to the execution step of gaining the intercepted human voice signal according to the preset microphone gain so as to obtain another gained intercepted human voice signal, or if so, gaining the complete human voice signal according to the preset microphone gain to obtain a gained human voice signal; and awakening intelligent voice equipment according to the gain human voice signal. The technical problem of low awakening rate of the intelligent voice device in the prior art is solved in the invention.

Description

technical field [0001] The present application relates to the technical field of microphones, and in particular to a wake-up method and device for an intelligent voice device, an electronic device, and a readable storage medium. Background technique [0002] At present, microphones are widely used in intelligent voice products such as smart wearables, smart home appliances, and smart speakers due to their advantages of high performance and low price. Judging whether the amplified human voice signal is the preset smart device wake-up word to wake up the smart device, but after the normal human voice signal is adjusted by the microphone, due to the low signal amplitude, signal distortion and signal adjustment delay Long-term problems will lead to a low wake-up rate of smart voice devices. Contents of the invention [0003] The main purpose of this application is to provide a wake-up method, device, electronic device and readable storage medium for an intelligent voice devic...
