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

我们可以通过几种方式表达我们的情感。话语的韵律特征就是手段之一。我们可以用不同的音高模式来发音“awanaino”这个句子，意思是“账户不正确”。通过这些音调模式，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。并研究了将陈述句转化为疑问句的方法，在-60Hz ~+60Hz范围内，每隔10 Hz改变一次句首和最高音部分的音高，合成了24个句子。我们准备了这24个和原始的话语。我们将这些话语随机排列成录音带，让16名日本人听录音并回答，发现了一个明显的趋势，即提高话语开头部分的音高，可以使其带有疑问和批评的意味。但是我们没有发现陈述句awanaino通过最高音高部分的音高变化而变成带批评的疑问句的倾向，我们得到了另一个大的成果。我们将1993年至2000年的研究成果整理成册，厚积薄发。对日语长元音的感知、单词重音与句子语调的结合、离域元音的音值、句子韵律特征的功能等方面的研究。我们收集了这些实验和研究成果，编成了两本书：一本是数据集，另一本是论文集。这些研究有助于弄清日语语音单位“白”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.
