The Opening Time and Opening-Quotient of the Vocal Cords During Phonation
Tamás Tarnóczy · The Journal of the Acoustical Society of America · 1951
The vowel sounds are produced by vibration of the vocal cords and are modified by the filtering effect of the resonant cavities. Thus, in the case of voiced speech sounds and of the sounds of singing, two factors play a part in the final shaping of the sound picture: the cord-tones and the resonators. The present paper deals with the cord-tones and with the peculiarities of vibration of the vocal cords.
