  • Model and filter circuit for modeling an acoustic sound channel, uses of the model, and speech synthesizer applying the model
    Patent number: 4542524
    Abstract: Speech and music phonation formed by spectral formants is synthesized by a composite filter containing parallel filters in cascade. The composite filter design is generated by partial-function expansion of the approximate sound channel transfer function ##EQU1## and the composite filter is implemented with mutually adjacent formants in cascade filter elements.
