Data processing system and method for speech recognition model, and speech recognition method

A data processing system for a speech recognition model, comprising:

• a cloud-side device, configured to:
• acquire a sample set, wherein the sample set comprises a plurality of sample pairs, and the sample pair comprises sample speech data and sample Chinese text;
• encode, by using an encoder, the sample speech data to obtain a speech feature of the sample speech data, wherein the encoder is pre-trained based on performing a Chinese pronunciation unit predicting task on pre-training speech data;
• input the speech feature into a decoder to obtain predicted Chinese text, wherein the decoder is pre-trained based on performing a text prediction task on a pre-training Chinese pronunciation unit;
• pre-train a model comprising the encoder and the decoder based on the predicted Chinese text and the sample Chinese text, and in a case where a pre-training stop condition is met, acquire a model parameter of a speech recognition model obtained by pre-training;
• wherein the cloud-side device is further configured to send the model parameter of the speech recognition model obtained by pre-training to an end-side device;
• the end-side device, configured to perform speech recognition on to-be-recognized speech data by using the speech recognition model to obtain target text corresponding to the to-be-recognized speech data.
