Sequential Unconstrained Minimization

(Hui Ling Lu)
(Google search: ``CCRMA Singing/Speech Synthesis'')

Klatt glottal (parabola) parameters are estimated jointly with vocal tract filter coefficients

Formulation resembles that of the equation error method for system identification
For phase alignement, we estimate
- pitch (time varying)
- glottal closure instant each period
Optimization is convex in all but the phase-alignment dimension
