Spoken language pronunciation quality evaluation method, device and equipment and storage medium

The invention belongs to the technical field of speech recognition, and discloses a spoken language pronunciation quality evaluation method, device and equipment and a storage medium. The method comprises the following steps: acquiring a plurality of sentence-level voice signals of a to-be-tested person; determining sentence-level posterior probability distribution scores in one-to-one correspondence according to the sentence-level voice signals; and performing quality evaluation on the sentence-level posterior probability distribution score through a trained preset quality evaluation neural network to obtain a spoken language pronunciation quality evaluation result of the to-be-tested person. Through the above mode, the sentence-level posterior probability distribution scores are determined according to the plurality of sentence-level voice signals of the speaker, and the plurality of sentence-level posterior probability distribution scores serve as features of the speaker level, include detailed information
