on the Functions of Pitch and Amplitude in case of Perceiving the Number of Morae of Japanese Long Vowels

我们可以用几种方式来表达我们的情感。我们话语的韵律特征是一种手段。我们可以用不同的音高模式来发“awanaino”这个句子，意思是“账目不正确”。通过这些音高模式，我们可以表达各种情绪。我们从被认为是陈述句的话语中合成了一些话语。研究了将陈述句改为批评疑问句的方法。我们每隔10Hz将声音的开头和最高音调部分的音高从-60Hz改变到+60Hz，合成了24个声音。我们准备了这24条和原始的话语。我们将这些话语随意排列成录音带，并让16名以日语为母语的人听录音并回答。我们发现了明显的倾向，即提高话语开头部分的音高，我们可以使其疑问句带批评。但我们没有发现陈述式“awanaino”通过改变最高音高部分的音高而转变为带批评的疑问句的趋势。我们又获得了一个大产品。我们从1993年到2000年收集和编辑了我们的研究成果，出版了两本厚厚的书。日语长元音的感知研究、单词重音与句子语调的结合研究、去中心化元音的语音价值研究以及句子韵律特征的功能研究。我们收集了这些实验和研究，并制作了两本书：一本是数据书，另一本是论文书。这些研究都有助于厘清日语语音单位“白字”的本质。

We can express our emotions by several means. The prosodic feature of our utterances is one of the means. We can pronounce the sentence 'awanaino, ' that means 'the account is not correct, ' with various kinds of pitch patterns. And with those pitch patterns we can express various emotions. We synthesized some utterances from the utterance which was perceived as a declarative sentence 'awanaino.' And we researched the method how we change the declarative sentence into the interrogative with criticism.We changed the pitches of the beginning of the utterance and the part of the highest pitch every 10Hz from -60Hz to +60Hz and made 24 synthesized utterances. We prepared these 24 and the original utterance. We made the audio tape with these utterances arranged at random order, and asked the 16 Japanese native speakers to listen to the tape and to answer.We found out the clear tendency that raising the pitch of the beginning part of the utterance, we can make it interrogative with criticism. But we could not find the tendency that the declarative 'awanaino' changes into the interrogative with criticism by means of any change of the pitch of the part of the highest pitch.We have obtained another big product. We made two thick books, gathering and editoring the fruit of our researches from 1993 to 2000. The researches on perceiving the Japanese long vowels, on the combination of the word accent and the sentence intonation, on the phonetic values of the devocalized vowels and on the functions of the sentence prosodic features. We collected these experiments and researches, and made two books : one of datae and another of papers. All of these researches are useful to clarify the essential qualities of 'haku, ' the phonetic unit of Japanese.
