Embodiment Construction

[0021] In order to make the object, technical solution and effect of the present invention more clear and definite, the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0022] See figure 1 , figure 1 Disclosed is a speech recognition based noise reduction method comprising:

[0023] S10. Acquiring the voice information A to be kept during the voice call;

[0024] S20. Identify the features of the voice information A, and store the feature model of the voice information A;

[0025] Specifically, the feature model of the speech information A includes loudness, pitch and timbre;

[0026] Loudness is mainly the size of the subjectively felt sound, which is determined by the amplitude and the distance from the sound source. The larger the amplitude, the loud...

Abstract

The invention provides a noise reduction method based on voice recognition and a terminal. The noise reduction method includes the steps that the characteristics of a to-be-retained voice message A are pre-recognized during voice communication, the voice message A is stored, the voice message A is stored during voice communication, other voice messages are denoised, thus the home terminal is denoised, and the communication quality of the other side in communication is improved; furthermore, other sound around a user is effectively eliminated, required single sound is retained only, the situation that noisy ambient sound around interferes with received people is avoided, the situation that the received people hears the ambient sound of the user can also be avoided, the environment of the user is judged, and thus the function of privacy protection is achieved to a certain extent; and if the terminals of both sides in voice communication use the scheme, the communication quality is greatly improved.

Description

technical field [0001] The invention relates to the field of voice call information, in particular to a voice recognition-based noise reduction method and a terminal. Background technique [0002] Making a voice call in a noisy environment will affect the clarity of the voice, especially when talking in an environment with mechanical or artificial noise such as construction sites and shopping malls, which will seriously affect the quality of the call. At this time, it is necessary to respond loudly to the remote terminal. In public places such as shopping malls, it is obviously inappropriate to speak loudly to the remote end of the terminal. [0003] The traditional noise reduction methods include: two microphones built into the mobile phone, one to maintain a clear call, and the other microphone to actively eliminate noise physically, by collecting external noise, using internal algorithms for processing, and emitting sound waves opposite to the noise, Use the principle of...
