项目摘要

A hundred syllables uttered by a female announcer were recorded. For each syllable, frequency under 400hz was cut off with a slope of 80dB/oct. by using a programable digital filter(PDF-1024) and the durtation of each syllable was made to be 450ms. These syllables were then labelled and saved so that they could be replayed instantly at any time by keyboard operation with DANAC 7000. Speech samples of sixty-seven syllables(Japanese choku-on) and /ta ka ma ga ha ra/ uttered by an adult female(F.W.) whose average hearing level was 103dB were recorded and their intelligibility was examined.Suprasegmental characteristics of /ta ka ma ga ha ra/ were analyzed by a dual channel FFT analyzer(B ＆ K 2032). Frequency higher than F_1 of each syllable was then cut off. On its duration and closure duration, syllables of the female announcer were superimposed to make fabrications of these syllables. Listening of (1) 67 syllables of F.W. (2) /ta ka ma ga ha ra/ of F.W. (3) the fabrications of 67 syllables (4) the fabrications of /ta ka ma ga ha ra/ was evaluated and analyzed.

一位女播音员说的一百个音节被录了下来。对于每一个音节，400 hz以下的频率被切断，斜率为80dB/oct。使用可编程数字滤波器(PDF-1024)，每个音节的时长为450ms。然后，这些音节被标记并保存，以便可以通过使用DANAC 7000的键盘操作在任何时间立即重播它们。一名成年女性发出的67个音节的语音样本(日语choku-on)和/ta ka ma ga ha ra/用双通道FFT分析仪(B&K 2032)分析其超音段特性。然后切断每个音节高于F_1的频率。在其时长和结束时长上，女播音员的音节被叠加，以制造这些音节。(1)F.W.(2)/ta ka ma ha ra/的67个音节的听力。(3)67个音节的制作。(4)对/ta ka ma ha ra/的制作进行评价和分析。
