Problems solved by technology

[0002] At present, after the smart device performs speech synthesis and generates the synthesized speech, it is necessary to evaluate and score the synthesized speech quality. In the prior art, the speech to be evaluated is usually evaluated manually. However, manual evaluation is often subjective, which will lead to The evaluation scores of the voices to be evaluated are not accurate, and since it is necessary to manually score the voices to be evaluated one by one, this evaluation method is also inefficient

Embodiment Construction

[0075] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0076] At present, the application of speech synthesis is very extensive. For example, the speech text to be synthesized is input into a smart device, and the smart device can perform speech synthesis on the speech text, output the synthesized speech, and perform speech synthesis on the smart device to generate After the speech is synthesized, it is necessary to evaluate and score the synthesized speech quality, so that relevant staff can adjust the ...

Abstract

The invention relates to the technical field of voice processing, and particularly relates to a voice evaluation method and device, and the method comprises the steps: obtaining to-be-evaluated voice;recognizing each phoneme of the to-be-evaluated voice by taking the to-be-evaluated voice as an input parameter based on a trained evaluation model, determining phoneme voice feature similarity between each phoneme and a corresponding preset standard phoneme; according to the to-be-evaluated voice and the corresponding preset standard voice, determining fluent speech feature similarity corresponding to the speech to be evaluated, the phoneme representing a phoneme corresponding to a minimum speech pronunciation unit; and determining an evaluation result of the to-be-evaluated voice accordingto the voice sub-voice feature similarity and the smooth voice feature similarity. Thus, the evaluation result of the to-be-evaluated voice is determined by combining the voice sub-voice feature similarity and the smooth voice feature similarity of the to-be-evaluated voice, and the voice evaluation efficiency and accuracy are improved.

Description

technical field [0001] The present application relates to the technical field of voice evaluation, in particular to a voice evaluation method and device. Background technique [0002] At present, after the smart device performs speech synthesis and generates the synthesized speech, it is necessary to evaluate and score the synthesized speech quality. In the prior art, the speech to be evaluated is usually evaluated manually. However, manual evaluation is often subjective, which will lead to The evaluation scores of the voices to be evaluated are not accurate, and since it is necessary to manually score the voices to be evaluated one by one, the efficiency of this evaluation method is also low. Contents of the invention [0003] Embodiments of the present application provide a voice evaluation method and device, so as to improve the efficiency and accuracy of voice evaluation. [0004] The specific technical scheme that the embodiment of the present application provides is...
