本文对粤语连续语音的基频（F0）声学分析进行了初步研究。通过理解表面F0轮廓是如何由许多共同作用和相互作用的语言或非语言因素决定的，我们的最终目标是促进高度自然的文本到语音合成的自动F0预测。提出了一种新的F0归一化方法，以有效地减少说话人F0范围的不希望的波动。对标准化的F0轮廓进行统计分析。具体来说，我们的调查重点是：（1）语调短语上的F0移动;（2）连续语音中的音调轮廓;（3）音调上下文的影响;（4）双音节词中的共发音音调轮廓。
This paper presents a preliminary study on acoustical analysis of fundamental frequency (F0) in continuous Cantonese speech. By understanding how the surface F0 contour is determined by many co-functioning and inter-playing linguistic or non-linguistic factors, our ultimate goal is to facilitate automatic F0 prediction for highly natural text-to-speech synthesis. A novel method of F0 normalization is proposed to effectively reduce the undesirable fluctuation of the speaker’s F0 range. Statistical analysis is performed on the normalized F0 contours. Specifically, our investigation is focused on: (1) F0 movement over intonation phrases; (2) tone contours in continuous speech; (3) effect of tonal context; and (4) co-articulated tone contours in disyllabic words.
