Abstract

A system and method for IP-based telephone communication utilizing speech-generated text is disclosed. An embodiment of the present invention includes an interface to the Internet for sending and receiving voice and video signals. In addition, the embodiment generates text signals corresponding to voice signals generated by the user. A transmission signal is generated from the text signals and the voice signals for transmission over the Internet. Further, the embodiment of the present invention includes an application which is capable of receiving video and/or speech-generated data transmitted by another device, and concurrently displaying the speech-generated data and video to a user. The speech-generated data may be converted to an audio signal and applied to a speaker concurrently with the video and speech-generated data. In this way, a user is capable of easily communicating speech-generated information to another user during periods of voice signal loss.

Claims

1. An IP-based telephone system, comprising:

a first receiver for receiving an audio signal from an audio source;

first circuitry for generating a first packet switched signal from said audio signal received by said first receiver;

a transmitter for transmitting said first packet switched signal;

a speaker;

a second receiver for receiving a second packet switched signal having an audio text signal and a typed text signal therein;

a speech generation circuit for generating a second audio signal from the typed text signal and applying the second audio signal to the speaker; and

a text application for displaying a plurality of text images corresponding to said audio text signal in substantial synchronicity with the second audio signal being applied to the speaker.

2. The IP-based telephone system of claim 1, wherein said second receiver is capable of receiving a third packet switched signal including a third audio signal, said IP-based telephone system further comprising a speaker and circuitry for transmitting said third audio signal to said speaker.

3. The IP-based telephone system of claim 1, wherein said second packet switched signal includes video data, said text application concurrently displaying said video data and said audio text signal to a system user.

4. The IP-based telephone system of claim 1, further comprising:

a third receiver, in communication with said first circuitry, for receiving video data from a video device, said first packet switched signal comprising said audio signal and said video data generated by the video device.

6. The method of claim 4, further comprising the steps of:

receiving a third IP-based signal having a second audio signal and a text signal;

displaying text images corresponding to the text signal; and

transmitting said second audio signal to a speaker in substantial synchronicity with the displaying of the text images.

5. A method for communicating over the Internet, said method comprising the steps of:

receiving an audio signal from an audio source;

generating a first Internet protocol (IP) based signal from said received audio signal;

transmitting the first IP-based signal;

receiving a second IP-based signal having an audio text signal and a typed text signal therein;

generating an audible signal based upon the typed text signal; and

displaying text images corresponding to said audio text signal in substantial synchronicity with the generating of the audible signal.

7. The method of claim 5, wherein said second IP-based signal includes video data, and said method further comprises the step of:

displaying said video data and said audio text signal corresponding to said second IP-based signal.

8. A telephone system, comprising:

a first receiver for receiving a packetized signal;

circuitry for extracting a first text signal and a second text signal from the packetized signal;

a display component,

an application for substantially concurrently displaying the first and second text signals on the display component;

a second receiver for receiving an audio signal and generating a third text signal therefrom;

an interface for converting the audio signal and the third text signal into a second packetized signal; and

a transmitter for transmitting the second packetized signal over a packet switched network.

9. The system of claim 8, wherein:

the application displays the first and second text signals in separate windows on the display component.

10. The system of claim 8, wherein:

the circuitry selectively extracts a video signal from the packetized signal; and

the application displays the video signal on the display component substantially concurrently with the display of the first and second text signals.
