Abstract

The invention discloses a TTS system performance test method, device and apparatus and a medium, is applied to the technical field of speech synthesis, and is used for solving the problem of low accuracy of a TTS system performance test method in the prior art. The method specifically comprises the steps of obtaining a text prediction result and a voice prediction result of an input text by a TTS system; based on the text prediction result, determining a text processing performance test result of the TTS system; based on the voice prediction result, determining a voice conversion performance test result of the TTS system; and determining a comprehensive performance test result of the TTS system based on the text processing performance test result and the voice conversion performance test result. Therefore, objective indexes in two aspects of text processing and voice conversion are adopted to test the performance of the TTS system, so that the comprehensive test of the performance of the TTS system can be realized, and the accuracy of the performance test of the TTS system can be improved.

Description

technical field [0001] The present application relates to the technical field of speech synthesis, in particular to a TTS system performance testing method, device, equipment and medium. Background technique [0002] The Text to Speech (TTS) system is a system that converts text into a synthetic voice that is as close to real human voice as possible according to the pronunciation specification of a specific language. It is widely used in scenarios such as voice assistants, smart homes, and map navigation. [0003] At present, Mean Opinion Score (MOS) is usually used to score the speech synthesized by the TTS system, and the performance of the TTS system is determined according to the speech scoring results. In this TTS system performance test method, the scoring standard is based on subjective feelings. Mainly, the scoring standards fluctuate greatly in different groups of people and different test corpora, and it is impossible to comprehensively evaluate the performance of ...
