An embodiment of the present invention provides a method for controlling a mute mode of a microphone, and fig. 1 is a flowchart of a method for controlling a mute mode of a microphone according to an embodiment of the present invention, and referring to fig. 1, the method includes:
and S10, acquiring voice data at the microphone end in the mute mode of the microphone.
Specifically, in the mute mode of the microphone, when a user utters voice, the audio data acquisition module acquires voice data at the microphone end, and converts an original voice signal into a voice pulse sequence to form voice data, so that the module mainly comprises signal processing processes of sound/electricity conversion, signal conditioning, sampling and the like.
And S20, determining whether the voice corresponding to the voice data is matched with the first set awakening word.
Specifically, after voice data of a microphone end is collected, whether voice corresponding to the voice data is matched with a first set awakening word is determined; after voice data at the microphone end are collected, an identification module is awakened to filter interference signals, and only the voice signals of 300-3400 Hz of a normal person are reserved; extracting a voice feature vector, and quantizing the extracted voice feature vector into a standard voice feature vector; and matching the quantized standard voice feature vector with the feature value vector of the first set awakening word, and further determining whether the voice corresponding to the voice data is matched with the first set awakening word. For example, the first set wake-up word may be "please open the microphone", if the voice uttered by the user is "please open the microphone", it is determined that the voice corresponding to the voice data matches the first set wake-up word, and if the voice uttered by the user is "please open the internet access cloud music", the voice corresponding to the voice data does not match the first set wake-up word.
And S30, if the two are matched, switching from the mute mode to the voice interaction mode.
Specifically, if the collected voice data of the microphone end is matched with the first set awakening word, the voice equipment is switched from the mute mode to the voice interaction mode, a normal voice interaction function is performed, the voice interaction action is responded, and the voice data is continuously sent to the voice server so as to respond to the voice request of the user.

And S240, if the two are matched, switching from the mute mode to the voice interaction mode.
Specifically, when a microphone of the voice device is in a mute mode state, the voice device only does not respond to voice interaction actions and sends voice data to the voice server, but an audio data acquisition module and a wake-up recognition module of the voice device are still in a working state, when a user sends voice, the audio data acquisition module can still acquire the voice data of a microphone end, the wake-up recognition module can still recognize the voice data of the microphone end acquired by the audio data acquisition module, and when the voice data is determined to be a first set wake-up word, the voice device is switched from the mute mode to the voice interaction mode.
Optionally, the microphone muting mode control method further includes:
in the voice interaction mode, if the voice corresponding to the collected voice data is matched with the first set instruction word, the awakening word in the awakening recognition module is replaced by the first set awakening word, and the voice interaction mode is switched to the mute mode.
Specifically, in the voice interaction mode, if the voice corresponding to the voice data acquired by the audio data acquisition module is matched with the first set instruction word, the awakening word in the awakening recognition module is replaced by the first set awakening word, the voice interaction mode is switched to the mute mode, the voice interaction action is not responded, and the voice data is not sent to the voice server. For example, if the first setting instruction word is set to "love classmates, turn off the microphone", in the voice interaction mode, when the voice sent by the user is ' love classmate ', the microphone is closed ', and after the voice data is collected and recognized, the awakening words in the awakening identification module are replaced by a first set awakening word of 'opening a microphone', and the voice interaction mode is switched into a mute mode, no response is made to voice interaction action, and no voice data is sent to the voice server until a user sends out voice of turning on a microphone, the voice equipment is awakened, the mute mode is switched into the voice interaction mode, and after the voice interaction mode is recovered to the normal voice interaction mode, the awakening words in the awakening recognition module are recovered to the initial awakening words, for example, the initial wake-up word is "love classmates", and the voice device continues to perform normal voice interaction after recognizing the initial wake-up word "love classmates".
The method for controlling the mute mode of the microphone provided by the embodiment of the invention adds the step of stopping the voice recognition operation and controlling the audio data acquisition module and the awakening recognition module to continue working when the voice data of the microphone end is acquired in the mute mode of the microphone. According to the embodiment of the invention, the voice recognition operation is stopped, the audio data acquisition module and the awakening recognition module are controlled to continuously work, the voice recognition operation of the voice equipment is stopped in a mute mode, corresponding awakening words are not needed any more, the mute effect is achieved, the audio data acquisition module and the awakening recognition module are controlled to continuously work, the voice equipment is awakened when the first awakening word is acquired, voice interaction is continued, the operation convenience of the microphone mute mode control is realized, and the natural human-computer interaction characteristic is embodied.
