The present document provides a way to extract the voice command signal from the mixed sound of noise and voice commands that improves the control of the air conditioner in noisy environments and increases the distance that the voice controls the air conditioner.
The technology of recognizing specific voice and filtering other noises can theoretically extract voice instructions from the voice, and feature extraction is carried out on mixed voice according to feature data of the voice, so that the effect of extracting the voice instructions is achieved.
Fig. 3 is a flowchart of a method for recognizing voice information according to an embodiment of the present application, and as shown in fig. 3, the method for recognizing a specific human voice and filtering out other voice interferences includes the following steps:
step one, a user sends a voice control instruction, and noise exists in the current environment;
secondly, the air conditioner collects the sound and carries out primary processing on the sound;
thirdly, the air conditioner extracts the characteristics of the sound and identifies a voice command;
and fourthly, the air conditioner performs corresponding control according to the acquired voice command.
For example, a user speaks a voice command for controlling an air conditioner in a room, noise and the voice command of the room are collected into an air conditioner processor at this time, a simple process is performed on the sound after sound is collected to filter out some noise, the sound which is difficult to distinguish whether the sound is the voice command is not processed temporarily, the air conditioner performs feature extraction on the sound after primary processing is completed, a feature signal of the sound of a specific user is extracted to analyze the voice command, and the voice command is responded according to the command sent by the user.
By adopting the embodiment, the voice air conditioner capable of identifying the voice of the specific person and filtering the interference of other voices distinguishes the voice control instruction and the noise signal according to the voice of the specific user, and the voice of some specific persons can be recorded by the air conditioner. And analyzing whether the voice command sent by the user during use is the voice of the specific users according to the voice characteristics recorded by the air conditioner, and filtering out interference sound at the same time, wherein if the voice command sent by the specific user is the voice of the specific user, the air conditioner controls the air conditioner according to the judged result. If the voice command of a specific user is given, other people cannot operate and control the voice air conditioner within a short period of time. Such as: after a user speaks any voice instruction to the air conditioner, the air conditioner extracts audio feature data of the user from voice, and filters other voice interference data according to the feature data, and at the moment, in a certain time (for example, 30 seconds), the air conditioner cannot be operated by voices of other people. The technology capable of recognizing the specific human voice and filtering other voice interference can effectively extract the voice instruction from the mixed voice, or can analyze the voice characteristic data according to the characteristics of the voice of the specific user, so that only the specific user can control the air conditioner. The technology can effectively improve the sensitivity of the air conditioner for receiving the voice signals, increase the distance of voice control and prevent the voice control from being influenced under a noisy environment.
