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.

关节器官的作用是将空气从肺部排出，然后产生语音。因此，可以合理地认为，从嘴唇排出的空气与语音声波、呼吸一起，是音素和发音的线索。但上述呼吸并未得到实践性的研究。因此，本研究试图探讨呼吸与言语的关系，并利用呼吸进行言语训练。首先，用恒温式热线风速计制作了用于测量呼吸的仪器。然后，用这种呼气测量仪研究正常受试者准确发音时从嘴唇排出的呼吸。因此，在呼吸速度波形中，峰值波形通常出现在从爆炸辅音到下一个元音的过渡处。研究发现，这一部分与音素和发音密切相关。因此，对前述部分的最大峰值、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的十分之一的范围进行了详细的检查。研究还考察了听力障碍受试者A、B(A为17岁的女性，B为13岁的男性)出生时嘴唇发出的下一次呼吸对发音爆炸性音节的训练。作为这些调查的结果，最大峰值及其量度的位置可以作为音素和发音的有用的表征。它们解释了发音的严谨性和发音装置的运动。通过上述实验，可以得出结论，用言语从嘴唇排出的呼吸对说话训练者是有用的。
