Abstract

A distributed speech recognition system provides for the convenient and expedited insertion of a new speech recognition engine. The system includes a central speech processor linked to at least one speech recognition engine. The at least one speech recognition engine includes means for addressing the central speech processor upon installation within the system. The means for addressing transmits to the central speech processor a message indicating its operating protocol and location to permit the central speech processor to identify and begin transmitting work thereto.

Claims

1. A distributed speech recognition system providing for the convenient and expedited insertion of a new speech recognition engine, comprising:

a central speech processor linked to at least one speech recognition engine;

the at least one speech recognition engine including means for addressing the central speech processor upon installation within the system, the means for addressing transmitting to the central speech processor a message indicating its operating protocol and location to permit the central speech processor to identify and begin transmitting work thereto.

2. The distributed speech recognition system according to claim 1, wherein the at least one speech recognition engine includes a speech recognition engine wrapper.

3. The distributed speech recognition system according to claim 2, wherein the at least one speech recognition engine communicates with the central speech processor using remote procedure call.

4. The distributed speech recognition system according to claim 2, wherein the speech recognition engine wrapper functions as an interface between the central speech processor and the at least one speech recognition engine.

5. The distributed speech recognition system according to claim 4, wherein the at least one speech recognition engine communicates with the central speech processor using remote procedure call.

6. The distributed speech recognition system according to claim 1, wherein the at least one speech recognition engine communicates with the central speech processor via remote procedure call.

7. The distributed speech recognition system according to claim 1, further including a plurality of speech recognition engines.

8. A method for the convenient and expedited insertion of a new speech recognition engine within a distributed speech recognition system, comprising the following steps:

linking a central speech processor to at leastone one speech recognition engine;

the at least one speech recognition engine addressing the central speech processor upon installation within the system with a message indicating its operating protocol and location to permit the central speech processor to identify and begin transmitting work thereto.

9. The method according to claim 8, wherein the at least one speech recognition engine includes a speech recognition engine wrapper.

10. The method according to claim 9, wherein the at least one speech recognition engine communicates with the central speech processor using remote procedure call.

11. The method according to claim 9, wherein the speech recognition engine wrapper functions as an interface between the central speech processor and the at least one speech recognition engine.

12. The method according to claim 11, wherein the at least one speech recognition engine communicates with the central speech processor using remote procedure call.

13. The method according to claim 8, wherein the at least one speech recognition engine communicates with the central speech processor via remote procedure call.
