## Abstract

Voice-activated telephone call connection method and corresponding voice server. According to the invention, the voice server (SV) comprises customised directories (A1, A2, A3, . . . ) associated with voice recognition patterns (M1, M2, M3, . . . ). These directories are continually updated. The request from the user (U1, U2, . . . ) is processed, firstly, by the voice server using the customised directory and, if the request is not successful, secondly, using the public directory (30), with the same dialog.
