Yy. Qi et N. Bi, SIMPLIFIED APPROXIMATION OF THE 4-PARAMETER LF MODEL OF VOICE SOURCE, The Journal of the Acoustical Society of America, 96(2), 1994, pp. 1182-1185
A simplified approximation of the four-parameter, voice source model d
eveloped by Fant er al. [STL-QPSR 4, 1-12 (1985)] is described in this
Letter. In our approximation, the computational complexity required t
o implement the four-parameter model is simplified without reducing mo
del accuracy. The simplified approximation accommodates rapid, on-line
adjustment of source parameters during speech synthesis.
