Problems solved by technology

[0004] The existing speech recognition method can only filter out the noise signal in the picked-up audio signal, but cannot reduce the noise signal in the speech recognition process. Therefore, when the picked-up noise signal is more complex, the accuracy of the speech recognition result is relatively low

Abstract

The invention provides a voice recognition method and device and a system. The method comprises the following steps: receiving a first noise signal sent by an external first acquisition module; generating a second noise signal according to the first noise signal; sending the second noise signal to an external conversion module, so that the conversion module plays a noise reduction audio signal generated according to the second noise signal, and the amplitude of the noise signal formed by superposing the noise reduction audio signal and the first noise signal is smaller than the amplitude of the first noise signal; and receiving a to-be-identified audio signal sent by an external second acquisition module, identifying the to-be-identified audio signal, and the to-be-identified audio signalcomprises a noise signal formed by superposing the first noise signal and the noise reduction audio signal. According to the method, the speech recognition accuracy can be improved.

Description

technical field [0001] The invention relates to the technical field of voice recognition, in particular to a voice recognition method, device and system. Background technique [0002] Since various noises emitted by household electrical appliances and noises in the environment will have different effects on speech recognition, therefore, noise reduction for speech recognition is very necessary. At present, after the speech recognition system picks up the audio signal (including noise signal and speech signal), it recognizes the noise characteristics according to the algorithm, and filters the noise signal from the audio signal, that is, only the speech signal is retained for subsequent speech recognition. [0003] The Chinese invention patent application with the application number 201911369839.1 discloses a control system for voice acquisition and recognition and its implementation method. The main feature of the invention is to provide a voice acquisition and voice recogni...
