Fundamental research to develop the talking trainer used breath.

发音器官扮演从肺部排出的空气的角色，然后产生语言。因此，我们有理由认为，从嘴唇排出的空气伴随着语音、呼吸，是音素和发音的线索。但是，上述呼吸并没有得到实际的研究。因此，本研究试图探讨说话时呼出的气，并利用呼出的气进行说话训练。首先，用恒温式热线风速计制作了测量呼吸的仪器。然后，用该呼气测量仪对正常受试者准确发爆炸性音节时从嘴唇排出的呼气进行测量。因此，峰值波形通常出现在呼吸速度波形中从爆炸辅音到下一个元音的过渡处。我们发现这个部分与音位和发音密切相关。因此，上述部分的最大峰值，测量其最大峰值的位置，下一个元音开始与最大峰值之间的间隔，以及峰值大于最大峰值十分之一的范围，都被彻底检查。听力受损的受试者A和B （A是十七岁的女人，B是十三岁的男人）出生时从嘴唇发出的下一个呼吸也被调查来训练发爆炸性音节。这些调查的结果是，最大峰值及其测量的位置可以作为音素和发音的有用表征。它们解释了话语的精确性和发音器的运动。从上面的实验中可以得出结论，说话时从嘴唇呼出的气对说话训练器是有用的。

Articulatory organs act air expelled from the lungs, and then speech is produced. Therefore it is reasonable to think that air discharged from lips with speech sound wave, breath, is the clues to the phoneme and the articulation. But the above mentioned breath is not practically researched. Hence this research attempts to investigate breath discharged with speech, and to use breath for the talking training. First the apparatus to investigate breath is made with constant temperature type hot-wire anemometers. Then breath that is expelled from lips when the normal subject pronounces explosive syllables precisely, is investigated with this expiratory measurement apparatus. Consequently the peaked waveform is usually found at the transition form the explosive consonant to the following vowel in the velocity waveform of breath. And it is found this portion is closely connected with the phonem and the articulation. So the maximum peak of the aforementioned portion, the position where its maximum peak is measured, the interval between the beginning of the following vowel and the maximum peak, and the range where the peak is greater than a tenth of the maximum peak value, are examined thoroughly. Next breath that is send out from lips when born hearing impaired subject A and B (A is the woman of seventeen years, and B is the man of thirteen years) train to pronounce explosive syllables, is investigated too.As the result of these investigations, the maximum peak value and the position of its measure serve as a useful characterization of the phoneme and the articulation. And they explain preciseness of utterance and the movement of articulator. From the experiment described above, it is concluded that breath expelled from lips with speech is useful of the talking trainer.
