Abstract
A vocoder for generating speech from a plurality of stored speech parameters which efficiently computes a band limited noise signal for use in the speech production model. The band limited noise signal generator includes a white Gaussian noise generator coupled to a band-width limiting filter. The resulting band limited white Gaussian noise signal is provided to a bank of modulators, each having predetermined modulation frequency. The outputs of each of the modulators are provided to variable gain units and summed together to produce the band limited noise signal.
