Abstract
A telecommunication terminal receives an analog speech signal from a user of the terminal and converts the analog speech signal into a digital signal. A vocoder applies source coding to the speech signal and extracts reconstruction parameters from the speech signal. The reconstruction parameters are modified so that the transmitted voice associated with the signal is modified.
