Problems solved by technology

[0003] However, since the GOP is an approximate calculation of the pronunciation confidence, the calculation of the GOP is complex, and often requires complex calculation steps to determine the GOP of the speech to be evaluated, resulting in low efficiency of the speech evaluation score determined based on the GOP

Abstract

The invention relates to a voice evaluation method and device, computer equipment and a storage medium. The method comprises the following steps: acquiring a to-be-evaluated voice, and performing voice processing on the to-be-evaluated voice to obtain a time alignment result and an audio feature of the to-be-evaluated voice; determining target phoneme features corresponding to a plurality of phoneme units corresponding to the to-be-evaluated voice according to the time alignment result and the audio features; obtaining a pronunciation feature corresponding to each phoneme unit, and performing first fusion processing on the pronunciation feature and a corresponding target phoneme feature to obtain a fusion feature corresponding to each phoneme unit; determining voice phonemes included in each whole sentence in the to-be-evaluated voice, and carrying out second fusion processing based on the fusion features of phoneme units to which the voice phonemes included in each whole sentence belong, so that statement features corresponding to each whole sentence are obtained; and determining an evaluation score of the to-be-evaluated voice according to the statement features. By adopting the method, the evaluation efficiency of voice evaluation can be improved.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a voice evaluation method, device, computer equipment and storage medium. Background technique [0002] At present, some language teaching applications can evaluate users' spoken pronunciation to help users improve their spoken pronunciation. Speech evaluation is generally divided into two steps: 1. Perform short-time Fourier transform on the speech to be evaluated, and then convert it into a corresponding spectrogram, and then extract GOP (goodness of pronunciation, pronunciation) from the spectrogram based on the engineering characteristics of the audio. Confidence parameter) 2. Input the extracted GOP to the evaluation module to obtain the corresponding speech evaluation score. [0003] However, since the GOP is an approximate calculation of the pronunciation confidence, the calculation of the GOP is complicated, and often requires complex calculation steps to det...
