Abstract
A speech analysis system includes a codebook () that stores speech spectral parameters corresponding to a speech spectral hypothesis. The speech spectral hypothesis may be combined with a noise spectral hypothesis and the combined hypothesis compared to a sensed signal via a discriminant function (). The discriminant function may be evaluated using the preconditioned conjugate gradient (PCG) process.
