Abstract

The present invention relates to establishing a media channel and a signaling channel between a client and a server. The media channel uses a chosen codec and protocol for communication. Through the media channel and signaling channel, an application on the client can utilize speech services on the server.

Claims

1. A method of communication between a client and a server, comprising:

establishing a media channel;

establishing a signaling channel; and

exchanging information between the client and the server through at least one of the media channel and the signaling channel.

2. The method of claim 1 wherein establishing the media channel further comprises establishing a codec and a protocol.

3. The method of claim 1 wherein exchanging information is performed in a Session Initiation Protocol (SIP) environment.

4. The method of claim 1 wherein exchanging information is performed in a web services environment.

5. The method of claim 1 wherein establishing the media channel includes proposing a codec and a protocol to be used for the media channel.

6. The method of claim 1 wherein establishing the media channel includes declaring an internet protocol address and a port associated with the internet protocol address.

7. The method of claim 1 and further comprising providing a list of at least one codec and at least one protocol used to establish the media channel.

8. The method of claim 7 and further comprising referencing the list to establish the media channel.

9. The method of claim 1 wherein exchanging information includes transmitting speech data over the media channel.

10. A computer readable medium having instructions for providing speech services, the instructions comprising:

receiving signaling information through a signaling channel according to an established signaling protocol;

receiving speech information through a media channel according to an established codec and protocol; and

processing the signaling information and the speech information.

11. The computer readable medium of claim 10 wherein the instructions further comprise performing speech recognition on the speech information.

12. The computer readable medium of claim 10 wherein the instructions further comprise establishing a session in a Session Initiation Protocol (SIP) environment.

13. The computer readable medium of claim 10 wherein processing the signaling information and the speech information is performed in a web services environment.

14. The computer readable medium of claim 10 wherein the instructions further comprise providing a Computer Supported Telecommunicates Application (CSTA) interface.

15. The computer readable medium of claim 10 wherein the instructions further comprise interpreting a Simple Object Access Protocol (SOAP) message.

16. The computer readable medium of claim 10 wherein the instructions further comprise processing the speech information to identify semantic information contained therein.

17. The computer readable medium of claim 10 wherein the instructions further comprise transmitting information to a specified port associated with an Internet Protocol (IP) address.

18. The computer readable medium of claim 10 wherein the instructions further comprise transmitting a Simple Object Access Protocol (SOAP) message.

19. A method for processing information in a computer network, comprising:

establishing a relationship between a client and a server in one of a SIP environment and a web services environment;

transmitting data from the client to the server according to a specified protocol, the data comprising audio data or text data;

converting the data from audio data to text data if the data is audio data and from text data to audio data if the data is text data; and

transmitting converted data from the server to the client according to the specified protocol.

20. The method of claim 19 wherein the specified protocol is based on CSTA (Computer Supported Telecommunication Applications).
