Abstract
Herein disclosed is a speech analysis-synthesis apparatus which resorts to a multi-pulse exciting method using a plurality of modeled pulses as a synthetic sound source if input speech is analyzed so that speech may be synthesized on the basis of the analyzed result. A factor for effecting perpetual weighting in a manner to correspond to the sound source pulse number is made variable, and the error between the input speech and the synthesized speech is perceptually weighted so that the amplitude and location of the train of the sound source pulses are so determined as to minimize said error.
