The invention discloses a voice enhancement method and system based on a noisy environment, which belongs to the field of speech and is used for solving the problem that the accuracy of user's voice data cannot be enhanced in a noisy environment. A decibel calculation module, a voice enhancement module and feature extraction module and an identity recognition module, the identity recognition module is used for identifying the identity of the user, and the recognition failure signal is obtained or recorded as a speech enhancement object, and the feature extraction module is used for extracting the speech feature of the speech enhancement object, extracting Obtain the voice feature package, the decibel calculation module is used to calculate the voice decibel in the geographical location of the voice enhancement object, and obtain the voice enhancement signal and the corresponding decibel mean value or the voice normal signal and the corresponding voice decibel value, the voice enhancement module For enhancing the voice of the voice enhancement object, the present invention facilitates the accuracy enhancement of the user's voice data in a noisy environment.
Description
technical field [0001] The invention belongs to the field of speech and relates to speech enhancement technology, in particular to a speech enhancement method and system based on a noisy environment. Background technique [0002] Voice is one of the most efficient and direct tools for human communication. However, when we carry out voice communication, we will inevitably be interfered by the noise in the surrounding environment, which will cause the received voice signal to be distorted, which will seriously affect the communication quality. Speech enhancement on the received speech signal is an effective means to improve the influence of environmental noise on the signal. Speech enhancement is the suppression of noise interference from the received signal, enhancing the strength of the speech signal of interest. It is one of the core technologies of modern communication. [0003] In the prior art, in a noisy environment, the voice data with small decibels is easily overw...
