A simplified approximation of the four-parameter LF model of voice source
Yingyong Qi, Ning Bi · The Journal of the Acoustical Society of America · 1994
A simplified approximation of the four-parameter, voice source model developed by Fant et al. [STL-QPSR 4, 1–12 (1985)] is described in this Letter. In our approximation, the computational complexity required to implement the four-parameter model is simplified without reducing model accuracy. The simplified approximation accommodates rapid, on-line adjustment of source parameters during speech synthesis.
