Abstract

A communication system includes communications equipment having a voice input device, an acoustic output device, and a visual display device. The communications equipment receives voice information from a user using the voice input device, converts the voice information into text, and communicates packets encoding the voice information and the text to a remote location. The communications equipment also receives packets encoding voice and text information from the remote location, outputs the voice information using the acoustic output device, and outputs the text information using the visual display device.

Claims

1. A method for communicating voice and text associated with a packet-based voice communications session comprising:

receiving local voice information from a local participant in a packet-based voice communications session having at least one remote participant;

converting the local voice information into local text;

generating a first stream of packets encoding the local text;

generating a second stream of packets encoding the local voice information;

detecting a degradation in a quality of the packet-based voice communications session;

in response to detecting the degradation in the quality of the packet-based voice communications session, communicating the first stream of packets to the remote participant using transmission control protocol (TCP); and

communicating the second stream of packets to the remote participant using user datagram protocol (UDP);

wherein the packet-based voice communications session comprises an Internet protocol (IP) telephony communications session.

2. The method of claim 1, further comprising:

receiving packets encoding remote voice information and remote text from the remote participant;

outputting the remote voice information using an acoustic output device; and

displaying the remote text using a visual output device.

3. The method of claim 1, further comprising determining that the packet-based voice communications session provides for a text communications session before communicating the first stream of packets to the remote participant.

4. The method of claim 1, further comprising displaying the local text using a visual output device.

5. An interface for a telecommunications device, the interface operable to:

receive packets encoding remote voice information and remote text of the voice information from a remote participant, wherein the remote voice information and the remote text are associated with a packet-based voice communications session with the remote participant;

detect a degradation in a quality of the packet-based voice communications session;

display using a visual output device; and

output the remote voice information using an acoustic output device;

wherein the packets encoding remote voice information and remote text comprise;

a first stream of packets encoding remote text generated by converting the remote voice information; and

a second stream of packets encoding remote voice information from the remote participant;

wherein the first stream of packets is communicated using transmission control protocol (TCP) in response to detecting the degradation in quality of the packet-based voice communications session and the second stream of packets is communicated using user datagram protocol (UDP); and

wherein the packet-based voice communications session comprises an Internet protocol (IP) telephony communications session.

6. The interface of claim 5, wherein the interface comprises a computer program embodied in a computer readable medium.

7. The interface of claim 5, further operable to output the remote voice information using speech synthesis to convert the remote text into an audio output.

8. The interface of claim 5, further operable to translate the remote text from a first language to a second language.

9. The interface of claim 5, further operable to determine that the packet-based voice communications session provides for a text communications session before receiving the second stream of packets.

10. The interface of claim 5, further operable to:

receive local voice information from a local participant in the packet-based voice communications session;

convert the local voice information into local text;

generate packets encoding the local voice information and the local text; and

communicate a first stream of packets encoding the local voice information and a second stream of packets encoding the local text to the remote participant.

11. The interface of claim 5, further operable to display both the local text and the remote text to the local participant using a visual output device.

12. Telephony communications software for communicating voice and text associated with a packet-based voice communications session, the software embodied in a computer readable medium and operable to:

establish the packet-based voice communications session with a remote location;

receive local voice information from a local participant in the packet-based voice communications session;

convert the local voice information into local text;

generate a first stream of packets encoding the local text;

generate a second stream of packets encoding the local voice information;

detect a degradation in a quality of the packet-based voice communications session;

in response to detecting the degradation in the quality of the packet-based voice communications session, communicate the first stream of packets to the remote location using transmission control protocol (TCP); and

communicate the second stream of packets to the remote location using user datagram protocol (UDP);

wherein the packet-based voice communications session comprises an Internet protocol (IP) telephony communications session.

13. The software of claim 12, further operable to:

receive packets encoding remote voice information and remote text from the remote location;

output the remote voice information using an acoustic output device; and

display the remote text using a visual output device.

14. The software of claim 12, further operable to determine that the packet-based voice communications session provides for a text communications session before communicating the first stream of packets to the remote location.

15. The software of claim 12, further operable to display the local text using a visual output device.

16. A communications system for communicating voice and text associated with a packet-based voice communications session comprising:

a first communications device operable to establish the communications session with a second communications device, to receive local voice information from a local participant in the communications session, convert the local voice information into local text, to generate a first stream of packets encoding the local text, to generate a second stream of packets encoding the local voice information, to detect a degradation in a quality of the packet-based voice communications session, to communicate the first stream of packets to the second communications device using transmission control protocol (TCP) in response to detecting the degradation in the quality of the packet-based voice communications session, and to communicate the second stream of packets to the second communications device using user datagram protocol (UDP); and

the second communications device operable to receive the packets from the first communications device, display the local text using a visual display device, and output the local voice information using an acoustic output device;

wherein the communications session comprises a voice over packet (VoP) telephone call.

17. The communications system of claim 16, wherein the second communications device is further operable to translate the local text from a first language to a second language.

18. The communications system of claim 16, wherein the second communications device is further operable to:

generate an audio speech signal using the local text; and

output the audio speech signal using the acoustic output device.

19. The communications system of claim 16, wherein the first communications device is further operable to determine that the packet-based voice communications session provides for a text communications session before communicating the first stream of packets to the second communications device.

20. A device for communicating voice and text associated with a packet-based voice communications session comprising:

means for receiving local voice information from a local participant in a packet-based voice communications session having at least one remote participant;
