Abstract

The application relates to a speech recognition method and device, a computer device and a storage medium. The above method is characterized by obtaining a target network layer from the network layersof a time delay neural network of band-down sampling; adding a second neural network to the target network layer, using the output data of the target network layer as the input data of the second neural network, wherein the second neural network comprises at least one layer of network; obtaining the to-be-recognized speech data, and inputting the to-be-recognized speech data to the time delay neural network of band-down sampling, and recognizing the to-be-recognized speech via the time delay neural network of band-down sampling and the second neural network to obtain a corresponding speech recognition result. By using the time delay neural network of band-down sampling and the second neural network to recognize the speech data jointly, the better speech recognition result can be obtained.

Description

technical field [0001] The present application relates to the technical field of audio processing, in particular to a speech recognition method, device, computer equipment and storage medium. Background technique [0002] Speech recognition technology generally refers to semantic recognition and voiceprint recognition; in a narrow sense, it refers to the understanding and recognition of speech semantics, also known as automatic speech recognition. Speech recognition technology is a technology that uses computers to recognize digital speech into text. In recent years, speech recognition technology has made great progress and has been widely used in many fields. [0003] A complete speech recognition system includes speech sampling module, feature extraction module and recognition module. The feature extraction module converts the input digital voice signal into the acoustic features used by the recognition system. The speech recognizer uses the acoustic model, dictionary and...
