Vowel Synthesis by Means of Resonant Circuits
Erich S. Weibel · The Journal of the Acoustical Society of America · 1955
Various ways of creating artificial vowels are discussed and compared from the viewpoint of coding efficiency. A method which requires seven parameters to specify any vowel is then introduced and described in detail. It is based on the realization of the transfer impedance of a nonuniform transmission line by lumped elements.
