WIPO Patent Application WO/2023/050301

A1

The present application relates to the technical field of speech recognition. Embodiments of the present application provide a speech quality assessment method, a speech recognition quality prediction method, and a speech recognition quality improvement method. First, a test speech is acquired; then speech quality of the test speech is assessed according to semantic related information of the test speech to determine whether a parameter of speech preprocessing needs to be adjusted, and speech recognition quality is predicted according to the assessed speech quality to determine whether a parameter of a speech recognition model needs to be adjusted; and a corresponding assessment result or prediction result is outputted, such that the parameter of the preprocessing or the speech recognition model can be adjusted according to the assessment result or the prediction result. According to the present application, the parameter adjustment process of the preprocessing and the speech recognition model in the speech recognition process can be decoupled.
