Abstract

A method for carrying out hands-free communication using a telecommunication terminal includes loading, at least temporarily, at least one program from a service server into the telecommunication terminal and implementing the at least one program for use at least for a duration of a communication connection. The at least one program implements a speech processing algorithm.
