As shown in fig. 1, an embodiment of the present invention provides a voice control method, which is applied to an intelligent air conditioner, and includes:
step 101: when sound information input by a current user is collected through at least three microphones, determining whether at least one piece of target sound information exists in the sound information collected by the at least three microphones, wherein the target sound information comprises at least one preset command word;
step 102: when at least one piece of target sound information exists in the sound information respectively collected by the at least three microphones, denoising each piece of target sound information respectively to obtain denoised target sound information;
step 103: extracting voiceprint information of the current user from each piece of denoised target sound information respectively;

step 105: when the current user is determined to have the right of controlling the body of the intelligent air conditioner, sending a target request for requesting information from an external cloud server to the cloud server so as to enable the cloud server to store the target request, wherein the target request comprises at least one command word;
step 106: and executing operation corresponding to an operation instruction returned by an external cloud server, wherein the operation instruction is determined by the cloud server according to the stored historical operation of the current user and the at least one preset command word in the target request.
In the embodiment of the invention, the voice information input by the current user is collected through the plurality of microphones, so that the voice information of the current user can be prevented from being missed; because different microphones are arranged at different positions on the intelligent air conditioner body, voice information input by a user may exist in sound information collected by different microphones, and also the distance between the current user and a certain microphone is relatively far, so that the sound information collected by the microphones is small and is not convenient to identify, and therefore whether target sound information comprising at least one command word exists in the collected sound information can be judged, and the sound information collected by the microphones is prevented from being sound generated by misoperation of the current user; when the target sound information is determined to exist, noise reduction processing can be performed on the target sound information firstly to reduce the influence of noise on the identification of the identity of the current user, then voiceprint information of the current user is extracted to determine the access authority of the current user based on the voiceprint information, and when the current user has the authority of accessing the intelligent air conditioner body, a target request can be sent to the cloud server based on a command word in the target sound information, so that the cloud server returns a corresponding operation instruction based on the historical operation of the current user and the current target request, the body of the intelligent air conditioner is enabled to operate according to the operation instruction, corresponding service is provided for the user, and the use experience of the user is improved.
In order to facilitate the recognition of the sounds emitted by the user in different directions relative to the intelligent air conditioner body, the at least three microphones are arranged on the front surface of the intelligent air conditioner body in a straight line shape, wherein the at least three microphones after being arranged are parallel to the ground level surface.
Because the intelligent air conditioner is usually placed close to a wall, the voice collection mainly comes from the front of the air conditioner within 180 degrees, and therefore, all the microphones are arranged on the front of the intelligent air conditioner in a linear array. The sound intensity corresponding to the sound information input by the current user and collected by the microphones respectively is used for judging the position of the current user in the sound source position relative to the body of the intelligent air conditioner, so that the user can transmit air to the sound source position or avoid the sound source position during air supply based on the sound source position of the user.
For example, the microphone 1, the microphone 2 and the microphone 3 are arranged on the intelligent air conditioner body in a straight line shape, the microphone 1 is located at the leftmost side of the intelligent air conditioner body, the microphone 2 is located in the middle of the intelligent air conditioner body, and the microphone 3 is located at the rightmost side of the intelligent air conditioner body; after the current user sends out the sound information, the sound intensity of the sound information collected by the microphone 1 is the largest, and the sound intensity of the sound information collected by the microphone 2 is smaller than that of the sound information collected by the microphone 1 and is larger than that of the sound information collected by the microphone 3. Therefore, the sound intensity of the sound information collected by the 3 microphones can be judged, the current user is located at the left position of the intelligent air conditioner body, hot air can be conveyed to the position if the working mode is 'hot air conveying', and the position is avoided when cold air is conveyed if the working mode is 'cold air conveying'.
Specifically, the more the number of microphones arranged on the body of the intelligent air conditioner is, the more accurate the sound source position is judged, the more voiceprint samples are, the more accurate the voiceprint processing result is, but the higher the cost is, and the more complicated the information processing technology is. Therefore, the aesthetic property and the voice recognition cost of the comprehensive intelligent air conditioner body are preferably 4, on one hand, the voice and the environmental noise can be effectively separated, the accuracy of far-field voice interaction is met, and on the other hand, the sound source position (including the left position, the middle position and the right position) can be effectively identified.
In an embodiment of the present invention, when at least one speaker is disposed on the body of the intelligent air conditioner, a linear distance between each speaker and each microphone is not less than a preset threshold.
Specifically, since the speaker is a device for playing sound, in order to avoid that the microphone collects sound information input by a user when the speaker plays sound, a straight distance between the speaker and the microphone is not smaller than a preset threshold, for example, 30cm or 50cm, so as to ensure that the microphone can work normally.
In order to improve the accuracy of identifying the voiceprint information of the user, in an embodiment of the present invention, before the performing noise reduction on each piece of target sound information respectively to obtain the noise-reduced target sound information, the method further includes:

The voice message may include a registration word required when performing identity registration of the user, for example, "registration voiceprint information". Voiceprint information of the user can be extracted from the voice information to form a 3D voiceprint model of the user. When target voiceprint information matched with the voiceprint information extracted from the target voice information exists in the stored 3D voiceprint model of the user, the current user can be determined to be a legal user, namely, the user voiceprint registration is carried out in the body of the intelligent air conditioner, and therefore corresponding service can be provided for the current user.
