SPEECH SYNTHESIS-BY-RULE USING HIGH-LEVEL PARAMETERS

拟议研究的目的是评估以下项目的可行性 基于一种新的语音合成方法的语音合成系统的开发 控制KLSYN88等共振峰合成器。新方法使用一个 高级(HL)参数的小集合(约10个)，结合 与计算的空气动力量一起被映射为 更大的RLSYN88参数集。此前的研究表明， HL方法简化了语音的规范，但产生了 高度可理解的合成输出。此外，还有许多规律性的问题 已经观察到了不同类型语音的HL规范 听起来，这增加了一套有效的规则可能是 定义用于从符号自动合成声音序列 输入。该提案寻求支持开发 中完整的按规则综合系统所需的规则 以评估可在多大程度上增加 合成规则的效率和语音的准确性 表示作为使用HL参数的结果。

The purpose of the proposed research is to assess the feasibility of developing a speech synthesis-by-rule system based on a new method for controlling formant synthesizers such as KLSYN88. The new method uses a small set (about 10) of high-level (HL) parameters which, in conjunction with calculated aerodynamic quantities, are mapped into values for the much larger set of RLSYN88 parameters. Previous research has shown that the HL method simplifies the specification of speech sounds, yet yields highly intelligible synthesis output. In addition, numerous regularities have been observed for the HL specifications of different types of speech sounds, raising the possibility that an efficient set of rules could be defined for synthesizing sound sequences automatically from symbolic input. The proposal seeks support for development of a sub set of the rules that would be needed for a complete synthesis-by-rule system in order to evaluate the extent to which there may be increases in the efficiency of the synthesis rules and in the accuracy of the speech representation as a consequence of using HL parameters.
