Abstract

The invention relates to the field of terminal artificial intelligence (AI), in particular, relates to the field of voice recognition, and provides an audio processing method and device, terminal equipment and a computer storage medium, wherein the method comprises the steps: obtaining a to-be-processed face image set and a to-be-denoised audio signal; extracting mouth features of each face imagein the to-be-processed face image set, and extracting frequency spectrum features of the to-be-denoised audio signal; inputting the mouth features of each face image and the frequency spectrum featureof the to-be-denoised audio signal into a preset neural network model to obtain a frequency spectrum mask; and processing the to-be-denoised audio signal by using the spectrum mask to obtain a targetaudio signal. The method can solve the problems that an existing face-based auxiliary noise reduction algorithm has high requirements for the computing power of terminal equipment, is difficult to operate on low-computing-power terminal equipment and is limited in application scene.

Description

technical field [0001] The present application belongs to the field of terminal artificial intelligence (AI), specifically related to the field of speech recognition, and particularly relates to an audio processing method, device, terminal equipment, and computer storage medium. Background technique [0002] Currently, many terminal devices have voice interaction functions, such as voice assistants and voice input methods. When the user uses these terminal devices, if the user is in a relatively quiet environment, the terminal device can more accurately identify the recorded audio data. [0003] However, once the noise level in the environment is high, and the terminal device is not equipped with appropriate noise reduction measures, the recognition accuracy of audio data will drop sharply. [0004] An effective noise reduction method is crucial for terminal devices with voice interaction functions. Some scholars have proposed an auxiliary noise reduction algorithm based o...
