Embodiment Construction

[0096] In order to more clearly understand the above objects, features and advantages of the present disclosure, the solutions of the present disclosure will be further described below. It should be noted that, in the case of no conflict, the embodiments of the present disclosure and the features in the embodiments can be combined with each other.

[0097] In the following description, many specific details are set forth in order to fully understand the present disclosure, but the present disclosure can also be implemented in other ways than described here; obviously, the embodiments in the specification are only some of the embodiments of the present disclosure, and Not all examples.

[0098] TTS technology can convert any text information into audible voice information. Existing TTS technologies usually utilize neural network models to achieve text-to-speech conversion. After the TTS model outputs speech, it is necessary to evaluate the synthesized speech quality. At pres...

Abstract

The present disclosure relates to a speech evaluation method, device, computer equipment, and medium, wherein the speech evaluation method includes: inputting test text into a speech synthesis model, obtaining a first speech corresponding to the test text output by the speech synthesis model; The audio feature and the audio feature of the second voice corresponding to the test text obtain the first similarity between the first voice and the second voice; determine the evaluation result of the first voice according to the first similarity and the known evaluation result of the second voice . Since the evaluation result of the second voice is known, the evaluation result of the first voice is determined according to the first similarity and the evaluation result of the second voice, which shortens the time of voice evaluation, reduces the interference of subjective factors of manual evaluation, and improves the The accuracy of the evaluation result improves the efficiency of voice evaluation.

Description

technical field [0001] The present disclosure relates to the technical field of speech processing, in particular to a speech evaluation method, device, computer equipment and media. Background technique [0002] Text To Speech (TTS) technology can convert text into speech output. With the rapid development of the artificial intelligence industry, TTS is widely used in scenarios such as voice assistants, map navigation, and audio reading, and people have higher and higher requirements for the quality of voice output by TTS. [0003] In the prior art, a manual evaluation method is usually adopted, that is, the speech output by the TTS model is evaluated and scored through a human hearing test. For example: different test listeners score the evaluation speech respectively to obtain the Mean Opinion Score (MOS) value, the score ranges from 0 to 5 points, and the larger the score, the better the speech quality. [0004] However, it is not efficient to evaluate the speech to be ...
