Embodiment Construction

[0040] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described below are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0041] figure 1 It is a flow chart of the first method for adaptively adjusting the speech recognition rate provided by the embodiment of the present invention, such as figure 1 As shown, the steps include:

[0042] Step S101: the terminal acquires the user's voice stream by collecting the user's voice data, and at the same time collects the ambient noise in all directions to obtain the omnidirectional noise data stream.

[0043] Specifically, multiple microphones are arranged on the surface of the terminal, distributed in different positions, one of which is used to collect user voice data, and the remaining microphones are used to collect noise in all ...

Abstract

The invention discloses a method and device for adaptively adjusting the voice recognition rate, and the method comprises the steps: carrying out the omnibearing collection of environment noises when a terminal obtains a user voice flow through collecting the voice data of a user, and obtaining the omnibearing noise data flow; determining a noise reduction coefficient according to the obtained omnibearing noise data flow; carrying out the noise reduction of the user voice flow through the obtained omnibearing noise data flow and the noise reduction coefficient, and eliminating the environment noise in the user voice flow; and carrying out the voice recognition of the user voice flow with the environment noise being reduced. The method guarantees the higher voice recognition success rate in a high environment noise environment, and can automatically adjust the play sound quality according to the environment noise.

Description

technical field [0001] The invention relates to terminal voice recognition technology, in particular to a method for adaptively adjusting voice recognition rate and a related device. Background technique [0002] The development of mobile terminals (such as mobile phones) is changing with each passing day, and the usage scenarios are becoming more and more complex. The voice recognition function has become a major feature of the development of mobile terminals because it can completely liberate hands. [0003] Speech recognition in the prior art basically focuses on the realization of the speech recognition function, and basically uses dual microphones to achieve noise reduction. One microphone is used as the main channel microphone to pick up useful sound source data, and the other microphone picks up background noise. The two microphones usually need to be separated physically, so in the hardware layout, the two microphones are distributed on both sides of the motherboard....
