The Development and Application of Speech Production Device for the Profound Speech Disordered

一名女播音员发出的一百个音节被记录下来。用可编程数字滤波器（PDF-1024）以80 dB/oct的斜率滤除400 Hz以下的频率，使每个音节的持续时间为450 ms。这些音节然后被标记和保存，以便它们可以在任何时候通过DANAC 7000的键盘操作立即重放。一名成年女性（F.W.）发出的67个音节的语音样本（日语choku-on）和/大卡ma ga ha ra/。用双通道FFT分析仪（B & K 2032）分析了/大卡ma ga ha ra/的超音段特征。每个音节高于F_1的频率被截断。在音长和闭音长上，女播音员的音节被叠加起来，使这些音节成为虚构的。听力（1）F.W. (2)/F.W.的大卡ma ga ha ra/ (3)（4）对/大卡ma ga ha ra/的加工进行了评价和分析。

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.
