Speech recognition system for electronic switches in a cellular telephone or personal communication network
First Claim
1. In a mobile telecommunications system that connects mobile telecommunications customers, each having a mobile unit, to land-based customers served by a telephone network, wherein incoming and outgoing calls are routed through a mobile telecommunications switching office connected to a group of cell sites that communicate with the mobile units, the improvement comprising a voice recognition system located at the mobile telecommunications switching office, the voice recognition system comprising:
- a voice recognizer for recognizing characters and commands spoken by a mobile unit customer;
announcing means; and
processor means, operative under the control of a program stored therein and responsive to receipt by the voice recognizer of a first spoken command from said mobile unit customer, for controlling the announcing means to request the mobile unit customer to enter information identifying a destination number to be dialed;
the processor means further operative under the control of said program and responsive to receipt by the voice recognizer of a second spoken command from the mobile unit customer, for transferring the identifying information received by the voice recognizer to the mobile telecommunications switching office.

Abstract
An advanced telecommunications system is provided for the recognizing of spoken commands over a cellular telephone, satellite telephone, or personal communications network. In the cellular application, for example, a Speech Recognition System interconnects either internally with or as an external peripheral to a cellular telecommunications switch. The Speech Recognition System includes an administrative subsystem, a call processing subsystem, a speaker-dependent recognition subsystem, a speaker-independent recognition subsystem, and a data storage subsystem. The Speech Recognition System also allows for increased efficiency in the cellular telephone network by integrating with the switch or switches as a shared resource. The administrative subsystem of the Speech Recognition System is used to keep statistical logs of pertinent call information. Pre-recorded instructional messages are stored in the memory of the call processing subsystem for instructing a user on his or her progress in using the system. The speaker-independent recognition subsystem allows the user to interact with the system employing non-user specific functions. User specific functions are controlled with the speaker-dependent recognition subsystem. User specific attributes collected by the recognition subsystems are stored in the data storage subsystem.
