Speech recognition system for electronic switches in a cellular telephone or personal communication network

Abstract

An advanced telecommunications system is provided for the recognizing of spoken commands over a cellular telephone (15), satellite telephone (14), or personal communications network (16). In the cellular application, for example, a Speech Recognition System (20) interconnects either internally with or as an external peripheral to a cellular telecommunications switch (12). The Speech Recognition System (20) includes an administrative subsystem (21), a call processing subsystem (23), a speaker-dependent recognition subsystem (25), a speaker-independent recognition subsystem (27), and a data storage subsystem (29). Pre-recorded instructional messages are stored in the memory of the call processing subsystem (23) for instructing a user on his or her progress in using the system. The speaker-independent recognition subsystem (27) allows the user to interact with the system employing non-user specific functions. User specific functions are controlled with the speaker-dependent recognition subsystem (25). User specific attributes collected by the recognition subsystems are stored in the data storage subsystem (29).
