The assessment of acoustic fidelity of synthetic speech is a main way of assessing the performance andfonction of a synthesis system. To find the causes of and to improve the speech of worse acoustic fidelity is just likethe feedback effect of hearing. The way of assessment now used generally is a subjective one which can not give aquantitative analysis for improving and it is quite complicated.

The assessment of acoustic fidelity of synthetic speech is a main way of assessing the performance andfonction of a synthesis system. To find the causes of and to improve the speech of worse acoustic fidelity is just likethe feedback effect of hearing. The way of assessment now used generally is a subjective one which can not give aquantitative analysis for improving and it is quite complicated. With human hearing characteristics considered together with the sensitivity of LSP parameters to their spectral envelope, the acoustic fidelity of synthetic CHINESEspeech is expressed in a quanitative way, and an objective assessment method for acoustic fidelity of synthetic CHINESE speech is thus proposed.

对于合成语音的音质进行评价,是评价合成系统使用价值和性能的一种主要方式.通过音质评价,找出影响音质的原因,反过来指导音质改善,这正好体现了人类发声时听觉的反馈作用.现行的评价方案多为主观评价,不仅不利操作,而且不能对改善音质提供定量的建议.为了实现对语音音质的客观评价,作者通过对LSP参数的频谱敏感度的研究,将其与听觉特性相联系,用频谱敏感度表征语音中对听觉敏感的成分,从而给出了符合人耳听觉特性的音质的定量描述,提供了一种对语音音质的客观评价方法.并通过实验验证了这种方法的正确性.

As the speech system is more and more complex, the quality tests are becoming more difficult, so there is a great demand for objective quality measurement methods.In this paper, the research has been done on theory and realization of objective speech quality evaluation. The importance of objective test is explained, and an overview of the components that make up the ITU-T PESQ model is presented. In addition, the applications of P.862 and the system design scheme of objective assessment are introduced.

语音质量评价始终是语音处理系统研发中极为关心和重视的问题。要对日益庞杂的语音系统进行测评 ,研制灵活、方便、快捷、可靠的语音质量评价系统极其必要。通过介绍语音音质客观评价方法的基本原理 ,分析 ITU- T最新建议标准 P.862中的 PESQ算法 ,最终提出了基于 PESQ算法的语音音质客观评价系统的软硬件实现方案 ,并重点介绍了系统各部分的设计思想、实现难点以及解决策略
