当前的文本到语音系统所产生的语调通常是平坦的或人工发声的。音高范围是影响因素之一，可以通过更详细的语言知识来改善。在这项研究中，阅读语音语料库进行分析，提供有关韵律结构和音高范围的信息，这可以用来改善语音合成的语调模型。研究结果表明，音高范围的变化在韵律结构的调组层次上最为明显，短语首、短语尾调组与短语中间调组的音高范围有显著差异。
The intonation produced by current text-to-speech systems is often either flat or artificial sounding. Pitch range is one of the contributing factors which could be improved by more detailed linguistic knowledge. In this study, a corpus of read speech is analysed to provide information about prosodic structure and pitch range, which can be used to improve the intonation models for speech synthesis. The results show how the pitch range variation is most apparent at a tone group level of prosodic structure, and how phrase initial and phrase final tone groups have significantly different pitch ranges from tone groups which are phrase medial.
