论文摘要
本文着重于基于HMM的语音综合框架中低调和超定义语音的分析和合成。首先，创建了一个新的法国数据库，创建了我们的需求，其中包含三个相同的集合，发音为三个不同程度的发音：中性，低调和过度划分的语音。在此基础上，进行了声学和语音分析。结果表明，一方面，发音程度显着影响声带和声门特征，另一方面，语音速度，电话持续时间，电话变化以及Glottal Stop的存在。最后，使用基于HMM的语音综合以及旨在评估生成的语音质量的客观和主观测试合成中性，低调和超定义语音。这些测试表明，综合的过度语音似乎不如中性和过度定性的语音自然渲染。
This paper focuses on the analysis and synthesis of hypo and hyperarticulated speech in the framework of HMM-based speech synthesis. First of all, a new French database matching our needs was created, which contains three identical sets, pronounced with three different degrees of articulation: neutral, hypo and hyperarticulated speech. On that basis, acoustic and phonetic analyses were performed. It is shown that the degrees of articulation significantly influence, on one hand, both vocal tract and glottal characteristics, and on the other hand, speech rate, phone durations, phone variations and the presence of glottal stops. Finally, neutral, hypo and hyperarticulated speech are synthesized using HMM-based speech synthesis and both objective and subjective tests aiming at assessing the generated speech quality are performed. These tests show that synthesized hypoarticulated speech seems to be less naturally rendered than neutral and hyperarticulated speech.
