Abstract

An apparatus and method for speech synthesis based on variable rate vocoding is presented. An input speech signal is encoded by a variable rate vocoder (202), and the parameters of the speech signal are stored in memory. To synthesize speech, a variable rate decoder (208) decodes the parameters to produce speech samples. A codec (210) converts the speech samples from a digital signal to an analog signal, which is broadcast through a speaker (212).
