摘要
The transfer function W (z) = A (z / yOne) / A (z / y2), In the speech coder analysis by synthesis using the short-term perceptual calibrating filter, the spectral expansion coefficient gammaOneAnd 2/RTI is dynamically adapted based on the spectral confinement factor obtained during the short-term linear prediction analysis. The spectral limiting factors used in this adaptation can constitute a representative limiting factor of the overall gradient of the voice signal spectrum and of the resonance characteristics of the short-term composite filter in particular.
