Problems solved by technology

However, in the current non-intelligent voice recognition products, when it is necessary to add the intelligent voice recognition function, because the non-intelligent voice recognition product itself does not have a sampling circuit and an ADC conversion module, it is impossible to realize the intelligent voice function on some non-intelligent voice products.

Abstract

The invention discloses an intelligent speech recognition recovery circuit and a recovery method, the recovery circuit comprises a speech control module, an audio processing module and an output module, the speech control module sends speech data to the audio processing module and receives the speech data; the audio processing module receives the speech data sent by the speech control module and further processes the speech data; and the output module receives and outputs the speech data further processed by the audio processing module. Preferably, the recovery circuit further comprises a sound effect algorithm processing module which is used for receiving the speech data sent by the speech control module, carrying out sound effect processing and returning the processed speech data to thespeech control module. According to the intelligent speech recognition and recovery circuit and the recovery method provided by the invention, the speech recognition function of a non-intelligent speech recognition product and an intelligent speech recognition product can be realized by saving the sampling circuit and the ADC conversion circuit.

Description

technical field [0001] The invention relates to the technical field of intelligent voice recognition, in particular to an intelligent voice recognition recovery circuit and recovery method. Background technique [0002] Intelligent voice recognition products, such as the voice recognition algorithm of smart speakers, need to perform echo cancellation processing. During this process, it is necessary to perform data retrieval on the audio data played by the smart speaker, and the retrieval data is used as a reference signal for echo cancellation processing. [0003] In the prior art, the audio recovery method of the smart speaker is mostly converted into a digital signal through the sampling circuit and ADC, and then input to the main chip through the I2S. Therefore, in the prior art, a sampling circuit and an ADC conversion module are required. However, in the current non-intelligent voice recognition products, when it is necessary to add the intelligent voice recognition fu...
