Speech recognition system for electronic switches in a non-wireline communications network
First Claim
1. A voice recognition system for use in a non-wireline telecommunications switch connected between a telephone network and at least one transmission site that communicates with non-wireline units, comprising:
- a voice recognizer having a speaker-independent recognition subsystem and a speaker-dependent recognition subsystem for recognizing characters and commands spoken by a non-wireline telephone unit customer, wherein the speaker-independent recognition subsystem recognizes predetermined control commands and digits and the speaker-dependent recognition subsystem recognizes control commands previously stored by the non-wireline telephone unit customer in an off-line process;
prompting means, responsive to a request for service, for providing a prompt to the non-wireline customer to enter at least one spoken identifier providing identifying information for directing a telephone call; and
processor means, operative under the control of a program stored therein and responsive to receipt by the voice recognizer of the at least one spoken identifier from the non-wireline unit customer, for transferring dialing information associated with the identifying information to the non-wireline telecommunications switch to enable routing of the telephone call.

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.

5. A voice recognition system for use in a non-wireline telecommunications switch connected between a telephone network and at least one transmission site that communicates with non-wireline units, comprising:
-
a voice recognizer having a speaker-independent recognition subsystem and a speaker-dependent recognition subsystem for recognizing characters and commands spoken by a non-wireline telephone unit customer, wherein the speaker-independent recognition subsystem recognizes predetermined control commands and characters and the speaker-dependent recognition subsystem recognizes control commands previously stored by the non-wireline telephone unit customer in an off-line process; announcing means, responsive to a service request from the non-wireline telephone unit customer, for providing an indication to the non-wireline telephone unit customer indicating that the voice recognizer is prepared to receive identifying information to control a call; and processor means, operative under the control of a program stored therein and responsive to receipt by the voice recognizer of a spoken command from said telephone unit customer, for controlling the announcing means to request the telephone unit customer to confirm whether identifying information for directing a telephone call entered by the non-wireline telephone unit customer has been properly recognized by the voice recognizer; the processor means further operative under the control of said program for transferring dialing information to the non-wireline telecommunications switching office if the identifying information has been properly recognized by the voice recognizer. - View Dependent Claims (6, 7, 8)

9. A non-wireline telecommunications switching office connected between a telephone network and a group of cell sites that communicate with non-wireline telephone units, comprising:
-
a non-wireline telephone switching exchange for routing incoming and outgoing calls between the telephone units and land-based customers served by the telephone network; a voice recognizer having a speaker-independent recognition subsystem and a speaker-dependent recognition subsystem for recognizing characters and commands spoken by a non-wireline telephone unit customer, wherein the speaker-independent recognition subsystem recognizes predetermined control commands and characters and the speaker-dependent recognition subsystem recognizes control commands previously stored by the non-wireline telephone unit customer in an off-line process; announcing means, responsive to a service request from the non-wireline telephone unit customer, for providing an indication to the non-wireline telephone unit customer indicating that the voice recognizer is prepared to receive identifying information to control a call; and processor means, operative under the control of a program stored therein and responsive to receipt by the voice recognizer of a spoken command from said telephone unit customer, for controlling the announcing means to request the telephone unit customer to confirm whether identifying information for directing a telephone call entered by the non-wireline telephone unit customer has been properly recognized by the voice recognizer; the processor means further operative under the control of said program for transferring dialing information to the non-wireline telecommunications switching office if the identifying information has been properly recognized by the voice recognizer. - View Dependent Claims (10, 11, 12)

13. A voice recognition system for use in a non-wireline line telecommunications switching office connected between a telephone network and a group of cell sites that communicate with non-wireline units, the non-wireline telecommunications switching office including a non-wireline telephone switching exchange for routing incoming and outgoing calls between the non-wireline units and land-based customers served by the telephone network, comprising:
-
a voice recognizer having a speaker-independent recognition subsystem and a speaker-dependent recognition subsystem for recognizing characters and commands spoken by a non-wireline telephone unit customer, wherein the speaker-independent recognition subsystem recognizes predetermined control commands and characters and the speaker-dependent recognition subsystem recognizes control commands previously stored by the non-wireline telephone unit customer in an off-line process; announcing means, responsive to a service request from the non-wireline telephone unit customer, for providing an indication to the non-wireline telephone unit customer indicating that the voice recognizer is prepared to receive identifying information to control a call; and processor means, operative under the control of a program stored therein and responsive to receipt by the voice recognizer of a spoken command from said telephone unit customer, for controlling the announcing means to request the telephone unit customer to confirm whether identifying information for directing a telephone call entered by the non-wireline telephone unit customer has been properly recognized by the voice recognizer; the processor means further operative under the control of said program and responsive to confirmation of the identifying information by the non-wireline unit customer for controlling the announcing means to prompt the non-wireline unit customer to answer a question uniquely associated with an authorized user of the non-wireline unit; and wherein the processor means is further operative under the control of said program and responsive to receipt of a correct answer to the question for transferring dialing information to the non-wireline telecommunications switching office for subsequent action if the identifying information has been properly recognized by the voice recognizer. - View Dependent Claims (14, 15, 16)
