项目摘要

This project was organized with the aim of realizing a compact rule-synthesis system which converts the input Kana-Kanji sentences into naturally sounding announcing speech. The system was composed of a small work station and a digital processor based speech synthesizer. The main results obtained are as follows :1. A word dictionary was constructed and stored in the hard disc memory of the work station. Each word item of the dictionary includes morpheme composition, phoneme representation, part of speech, type of declension/conjugation, accent type and index of importance.2. A method for morpheme analysis was developed which decomposes the input sentences into word strings. This method is based on the word template matching with longer the better policy, and checking of the propriety in the conjunction between neighboring words. A method for linguistic analysis was also developed which performs syntactic and semantic analyses for the unit segmented by the punctuation marks and represen … More t the obtained syntactic structure of the sentence using terms of clause boundary, ICRLB (immediate constituent with recursively left-branching structure) boundary, etc.3. A program was constructed on the work station which generates phone and prosodic symbols using results of word segmentation (including indices of importance) and the information on syntactic boundaries.4. A new type of terminal analog speech synthesizer was developed consisting of four separate cascade paths simulating the vocal transfer functions of the four different speech categories and three types of excitation sources, viz., glottal waveform, fricative noise and plosive noise. The outstanding development in the speech quality was observed typically for the stop consonants.5. Syllable templates for above mentioned speech synthesizer were constructed for all possible Japanese syllables and stored in the hard disc memory of the work station.6. A program was developed which concatenates stored syllable templates and produces temporal pattern of feature parameters of continuous speech. The concatenation of vowel and vowel-like sounds was conducted using the method based on the technique of representing formant trajectories by the linear combination of aim functions.7. A module-type small terminal analog speech synthesizer was developed which generates synthesized speech with the inputs of temporal patterns of acoustic features. The synthesizer was composed of a digital signal processor and other electronic components.8. The module-type synthesizer was inserted into the work station to construct a total system for the output of announcing speech. Less

这个项目的目的是实现一个紧凑的规则合成系统，将输入的假名汉字句子转换成自然的声音宣布讲话。该系统由小型工作站和基于数字处理器的语音合成器组成。主要研究结果如下：1.建立了一个单词词典，并将其存储在工作站的硬盘存储器中。词典的每个词条包括词素构成、音素表示、词性、变格/变位类型、重音类型和重要性指数.提出了一种将输入句子分解为词串的语素分析方法。该方法基于词模板匹配的长优策略，并对相邻词之间的连接进行适当性检查。本文还提出了一种语言分析的方法，它对标点符号分割的单元进行句法和语义分析， ...更多信息利用小句边界、ICRLB（immediate constituent with recursively left-branching structure）边界等术语对得到的句子句法结构进行测试。在工作站上编制了一个程序，利用分词结果（包括重要性指标）和句法边界信息生成音素和韵律符号.研制了一种新型的终端模拟语音合成器，它由四个独立的级联通道组成，模拟四种不同语音类别的声音传递函数和三种激励源，声门波形、摩擦音和爆破音。语音质量的显著发展主要表现在塞音上。上述语音合成器的音节模板是为所有可能的日语音节构造的，并存储在工作站的硬盘存储器中。开发了一个程序，它连接存储的音节模板，并产生连续语音的特征参数的时间模式。采用基于目标函数线性组合表示共振峰轨迹的方法，实现了元音和类元音的拼接.研制了一种模块式小型终端模拟语音合成器，它以声学特征的时间模式作为输入，产生合成语音。该合成器由数字信号处理器和其他电子元件组成。将模块式合成器插入工作站，构成一个完整的广播语音输出系统。少
