In general, the shorter the length of the microphone's sound hole, the lower the energy loss when the sound wave reaches the microphone. Usually the length of the microphone's sound hole is 9.5mm. If only changing the length of the sound hole does not meet the desired effect; at the same time, when the user presses the remote control When 100 issues a command, the remote control 100 will also capture the audio data of the terminal device corresponding to the remote control 100. If an algorithm is used to filter out the audio data of the terminal device corresponding to the remote control 100 when recognizing the user's command, speech recognition will still not be improved. Accuracy; in the existing solution, the third microphone 313 is a zero-power digital microphone, and the first microphone 311 is an ordinary digital microphone. Therefore, when the surrounding environment is lower than 45dB, the third microphone 313 will automatically enter the zero-power mode. The third microphone 313 needs a sound greater than 45dB to wake up and start working, or when waking up the third microphone 313, there will be a system delay, which affects the accuracy of speech recognition. Only when the low power consumption mode of the third microphone 313 is turned off, the speech recognition The accuracy has not improved significantly either.

In a specific implementation, after obtaining the first sound data obtained by the first microphone 311 and the vibration noise data obtained by the second microphone 312, an algorithm is used to filter out and subtract the vibration noise data in the second microphone 312 to obtain the following results: The third sound data includes the vibration part when the user touches the touch screen area.

This embodiment determines the compared audio data in the first sound data by performing audio comparison between the vibration noise data and the first sound data; performs noise reduction and filtering on the first sound data according to the compared audio data to obtain the third sound data. . Audio comparison is performed between the vibration noise data and the first sound data, and the first sound data is noise-reduced and filtered based on the compared audio data, thereby improving the accuracy of the noise-reduction filtering, thereby obtaining the third sound data excluding noise.

It should be understood that because the shorter the length of the sound receiving hole of the microphone, the lower the energy loss when external sound waves reach the microphone. Therefore, the length of the sound receiving holes of the first microphone 311 and the third microphone 313 in the remote control 100 is 6 to 9.5 mm. range, but in order to achieve a more accurate speech recognition rate, in this embodiment, the lengths of the sound receiving holes of the first microphone 311 and the third microphone 313 are both set to 6 mm.

The remote control 100 in this embodiment uses the above method to add a second microphone 312 without a sound hole below the functional component 2, so that the second microphone 312 accurately collects the vibration noise data of the functional component 2 in the functional area 11, and based on the vibration The noise data identifies the user's voice data corresponding to the remote control 100, reducing the interference of noise on the user's voice data, while improving the recognition accuracy of the user's voice acquired by the remote control 100 and the accuracy of the far-field sound pickup of the remote control 100. .
