项目摘要

(1)Definition of the goal and choice of target languages It was decided that the generative model for the fundamental frequency contours (henceforth F_0contours) of the common Japanese, already established by the principal investigator and his colleagues, shall be used as the basis and shall be extended to apply to other languages, that the extraction of linguistic information on lexical accents, syntactic structures and locations of foci is to be modeling a separate research project, and that British English, German and Greek are to be selected as examples of target languages.(2)Elucidation of the generative models for F_0 contours of British English, German, and GreekSpeech samples of text reading and dialogue by a number of native male and female speakers of the three languages were collected and analyzed. The results indicated that F_0 contours of speech of these languages can be generated using the same mechanism as for those of the common Japanese, but the patterns of control commands can be different among various languages. British English differs from Japanese in the timing and magnitude of the phrase commands as well as in the fact that the polarity of accent commands can be both positive and negative. German differs from Japanese in that it has two types of phrase commands ; the impulse type and the step function types. On the other hand, the constraints on the control commands of Greek are found to be identical to those of Japanese.(3)Construction of a system for rule synthesis of prosodic features of multiple languagesOn the basis of the above-mentioned results, a system of prosodic symbols and a set of rules for determining the polarity, magnitude and timing of control commands were devised for each target languages, and a system for rule synthesis of prosodic features was constructed, using the system for the common Japanese as its basis.

(1)目标的确定和目标语言的选择决定以主要研究者及其同事已经建立的普通日语基频轮廓（以下简称F_0轮廓）生成模型为基础，应扩展到适用于其他语言，关于词汇重音、句法结构和焦点位置的语言信息的提取将被建模为一个单独的研究项目，并且将选择英国英语、德语和希腊语作为目标示例(2)英式英语、德语和希腊语F_0轮廓的生成模型的阐明收集并分析了这三种语言的一些母语男性和女性的文本阅读和对话的语音样本。结果表明，这些语言的 F_0 语音轮廓可以使用与普通日语相同的机制生成，但不同语言的控制命令模式可能不同。英式英语与日语的不同之处在于短语命令的时间安排和大小，以及重音命令的极性可以是正的也可以是负的。德语与日语的不同之处在于它有两种类型的短语命令；脉冲型和阶跃函数型。另一方面，发现希腊语的控制命令约束与日语的控制命令相同。 (3)多语言韵律特征规则综合系统的构建在上述结果的基础上，提出了一种多语言韵律特征规则综合系统为每种目标语言设计了韵律符号和一套确定控制命令的极性、大小和时间的规则，并以普通日语系统为基础构建了韵律特征的规则合成系统。
