Sound pickup adjustment method, control terminal and computer-readable storage medium

Abstract

The invention discloses a sound pickup adjustment method, which comprises the following steps: obtaining the orientation information of a sound source; determining an angle of rotation of the loudspeaker according to the azimuth information. The gain corresponding to each microphone is determined according to the determined angle and the position of the plurality of microphones, and the pickup parameter of the corresponding microphone is updated according to the determined gain. The invention also discloses a control terminal and a computer-readable storage medium. A sound pickup adjustment method of the invention realizes that the sound pickup signals recorded by different microphones tend to be close to each other or be adjusted to be consistent. Thus, an ideal speech input is provided for the intelligent speech recognition algorithm of the intelligent sound box, the performance of the speech recognition of the intelligent sound box is guaranteed from the source, and the positioningaccuracy of the sound source of the intelligent sound box and the effect of the echo cancellation are improved.

Description

technical field [0001] The invention relates to the field of sound pickup, in particular to a sound pickup adjustment method, a control terminal and a computer-readable storage medium. Background technique [0002] Smart speakers are upgraded products through which consumers can use voice to access the Internet, such as ordering songs, shopping online, or understanding the weather forecast. In addition, they can also control smart home devices, such as opening curtains and setting refrigerators through smart speakers. Temperature, let the water heater heat up in advance, etc. Due to its powerful functions and good user interaction experience, smart speakers are becoming more and more popular among consumers, and their development momentum has been advancing rapidly in recent years. [0003] In order to achieve a better interaction effect, most smart speakers use a microphone array composed of four to eight microphones for far-field sound pickup. However, due to the large n...

Problems solved by technology

[0004] The embodiment of the present application provides a sound pickup adjustment method, which solves the problem that in the prior art, due to the large number of microphones and the difference in the size of the sound pickup signals recorded by different microphones, the smart speaker's ability to pick up the microphones is affected. To solve the problem of speech recognition of audio signals, the pickup signals collected by different microphones tend to be close or adjusted to be consistent, thus providing an ideal voice input for the smart speaker’s smart speech recognition algorithm, and ensuring smart speakers from the source. The performance of speech recognition helps to improve the accuracy of sound source localization of smart speakers and the effect of echo cancellation
