A comprehensive study of the transcription of Japanese sounds using the International Phonetic Alphabet -For the establishment of standards-

文化科学和工程科学领域的研究人员合作制定了使用国际音标（IPA）的日语语音转录标准。也就是说，我们整合了语音学、音系学等语言学方面、日语教育等语言教育方面、声音的声学分析、语音识别、语音合成等声学工程学和语音处理方面的研究成果，制定了将IPA作为日语语音描述的全球标准的标准。我们以声音资料为研究对象，除了利用现有的声音资料库外，也记录、搜集、编辑我们自己的声音资料库。根据问卷调查的结果，我们选择了最多变的声音，并在我们的研究中对它们进行了声学分析。为了对这些语音进行对比研究，我们还进行了 ...更多信息 其他语言语音的声学分析。为了建立更为客观的转写标准，我们将声学分析方法应用于通过听觉印象进行的声音转写，并提出引入一种新的声学特征系统，使我们能够进行定量和定性的比较。我们还探索了将国际音标的问题应用于日语教学和残疾人教学等问题的方法。本研究的某些方面可以应用于计算机辅助日语学习系统的开发。在IPA的计算机处理方面，我们考虑了目前IPA数字编码存在的问题，提出了一种新的编码系统。此外，我们将IPA转录系统引入语音处理领域，如语音合成和语音识别，目的是建立一个描述和转录合成日语声音的标准。在语音识别方面，我们将尝试使用IPA作为一种独立于语言的编码系统。少

Researchers in the fields of cultural and engineering science have cooperated to establish standards for the transcription of Japanese sounds using the International Phonetic Alphabet (IPA). In other words, we have established standards for introducing IPA as a kind of global standard for the description of Japanese sounds, through integrating research findings of linguistic aspects such as phonetics and phonology, of language educational aspect such as Japanese language education, and of acoustic engineering and speech processing aspects such as the acoustic analysis of sounds, speech recognition, and speech synthesis. Concerning sound materials as our research objects, we not only utilize the existing sound database but also record, gather, and edit our own sound database. Following the results of questionnaires, we have picked up the most variable sounds and made acoustic analyses of them in our research. In order to make a contrastive study of these sounds, we have also carried out … More acoustic analyses of speech sounds of other languages. To establish more objective standards for transcription, we have applied the method of acoustic analysis to sound transcription by means of auditory impressions, and propose to introduce a new the acoustic feature system that enables us to make quantitative and qualitative comparisons. We have also searched for ways of applying the problems of IPA transcription to such problems as the teaching of the Japanese language, and of the handicapped. Certain aspects of this research can be applied to development of the computer assisted Japanese learning systems. Concerning the computer processing of IPA, we have considered the existing problems of the current numerical codes for IPA and propose a new coding system to solve those problems. Furthermore, we introduce the system of IPA transcription to the field of speech processing as speech synthesis and speech recognition for the purpose of establishing a standard for describing and transcribing synthesized Japanese sounds. Concerning speech recognition, we will try to utilize IPA as a kind of language independent coding system. Less
