项目摘要

The final aim of this theme is the realization of a voice montage system, which attempts to reproduce with the speech synthesis technique an utterance of a person that a listener remembers. With the support of this grant, we have explored six fundamental problems needed to achieve the aim. The outcomes of our endeavors toward attaining the goal are described below:(1).Everyday expressions associated with voice quality and speaking style :The elaboration on the extraction from various lexical sources resulted in 1,102 expressions.(2).Acoustic correlates of the expressions :Acoustic correlates of vocal age that have remained unsolved in speech synthesis have extensively been investigated and the speaking rate, pitch contour and irregularities in the speech waveform were found to be of vital importance.(3). Memory of the utteranceCross-linguistic perceptual experiments showed that the memory of the voice quality of an utterance was almost independent of the language of the utterance.(4).Presentation strategy of voice samples :Audio-visual interaction was found to be significant, suggesting an importance of the combination of the voice and visual display in realizing the voice montage.(5).Similarity assessment of synthetic speech :Similarity of voice quality of the utterances was found to be preserved for a long period of time but speaker individuality of the utterances was not necessarily maintained in the memory.(6).Flexible speech synthesis technology :The ARX analysis-synthesis method was further improved, in particular for GUI, allowing the user to have more flexible and easy manipulation in speech synthesis.The outcomes mentioned above were integrated into an experimental system of voice montage, which primarily focuses on the reproduction of the voice quality of the utterance. Further elaboration on the problem (1) above, especially on exploring the expressions related to speaking style is necessary to attain the final goal of the project.

这一主题的最终目标是实现语音蒙太奇系统，该系统试图用语音合成技术再现听者记住的一个人的话语。在这笔赠款的支持下，我们探讨了实现这一目标所需的六个基本问题。我们为实现这一目标所做的努力成果如下：(1).与语音质量和说话风格相关的日常表情：从各种词汇来源中提取的精细化得到了1102个表情。(2)表情的声学相关性：人们广泛地研究了语音合成中尚未解决的发声年龄的声学相关性，发现语速、基音轮廓和语音波形中的不规则性是至关重要的。话语的记忆跨语言知觉实验表明，话语的音质记忆几乎与话语的语言无关。(4).语音样本的呈现策略：视听交互被发现是显著的，这表明声音和视觉显示的结合在实现声音蒙太奇中的重要性。(5)合成语音的相似性评估：发现话语的声音质量的相似性被发现在很长一段时间内被保留，但话语的说话人个性不一定被保持在记忆中。(6)灵活的语音合成技术：ARX分析-合成方法进一步改进，上述结果被集成到一个语音蒙太奇实验系统中，该实验系统主要关注于语音质量的再现。为了达到项目的最终目标，有必要对上述问题(1)作进一步的阐述，特别是探索与说话风格有关的表达方式。
