Abstract:
A speech processor comprising:a compressor signal multiplier for varying an amplitude of an input signal representing a speech waveform in accordance with a gain control signal and for providing a multiplied input signal;a feedback stage for receiving the multiplied input signal from the compressor multiplier and for providing the gain control signal representing a gain for providing an approximately constant peak level over an impulse portion and a decay portion within glottal pulses of a vocal tract response waveform represented by the input signal;a speech processor signal multiplier for varying the amplitude of the input signal representing the speech waveform in accordance with the gain control signal and for providing an output signal; anda delay means for providing the input signal to the speech processor signal multiplier such that the gain of the speech processor signal multiplier is adjusted to a desired level for a peak of the impulse portion of the vocal tract response waveform represented by the input signal at approximately the instant that the portion of the input signal representing the peak of the impulse portion is input to the speech processor signal multiplier.
