Dialling method for establishing a connection in a telephone switching system with digital speech transmission

Abstract

Abstract 1. A dialling method for establishing a connection in a telephone exchange system, wherein the calling subscriber keys the dialling information, which corresponds to his connection request, into the telephone exchange system in the form of a speech statement by means of the respective subscriber station (1), wherein the dialling information is transmitted to an analogue/digital conversion device (6), which is provided for the digitalisation thereof, and to a speech recognition device (7) connected thereto, wherein the speech recognition device (7) deciphers the dialling information, edits it and transmits it to a dial receiving set (8) for further processing, whereupon the required connection is established, characterised in that the telephone exchange system itself is a system with digital speech transmission, that in order to facilitate the recognition of the speech statement a personal identification (5) of the calling subscriber with speech samples or voice characteristics of the calling subscriber, which are applied to said identification for example in accordance with a magnetic recording process, is inserted into an identification scanning device (4) which is arranged in the subscriber station (1), and that the identification scanning device (4) scans the speech samples or voice characteristics and transmits them to the speech recognition device (7), whereupon the speech statement is recognisable for the speech recognition device (7) by means of the speech samples or the voice characteristics.
