Abstract

A method and system of providing network based transcription of free-form speech signals. A speech signal is recorded as a digital audio file in a storage medium and is then streamed over a data network to a client terminal for transcription. As the speech signal arrives, it is buffered in memory at the client terminal while a streaming player application plays the signal to a transcriptionist. The transcriptionist then conveniently listens to and transcribes the speech signal as it is being played. The invention advantageously avoids the need to physically transfer and download the full digital audio to a transcriptionist computer or to transport physical storage media, such as tapes or CD-ROM from the place of recording to the place where the recorded voice signals will be transcribed.

Claims

1. A method of providing network based transcription of a voice signal comprising, in combination:

receiving the voice signal;

storing a digital audio file representative of the voice signal in a file store associated with a server, the server being accessible over a data network, and the server being adapted to stream the digital audio file over the data network to a client terminal, the client terminal providing a plurality of streaming controls to enable a user at the client terminal to selectively play the voice signal represented by the digital audio file as the digital audio file is streamed to the client terminal;

the client terminal sending to the server a request to begin streaming the digital audio file over the data network to the client terminal;

the server receiving the request;

in response to the request, the server beginning to stream the digital audio file over the data network to the client terminal; and

as the streamed digital audio file arrives at the client terminal, (i) the client terminal receiving the digital audio file and audibly playing the voice signal represented by the digital audio file and (ii) a user at the client terminal transcribing the voice signal audibly played by the client terminal,

wherein the client terminal may send control signals to the server to pause and stop streaming of the digital audio file, and the server may respond to the control signals, respectively, by pausing and stopping streaming of the digital audio file over the data network to the client terminal.

2. A method as claimed in claim 1, wherein receiving the voice signal comprises receiving a call from a person via a telephone network and capturing a speech signal generated by the person, whereby the voice signal comprises a response to a voice prompt.

3. A method as claimed in claim 2, further comprising providing the voice prompt to the person via the telephone network, wherein the voice prompt is associated with a promotional survey, and wherein the voice signal comprises a response to the voice prompt.

4. A method as claimed in claim 1, wherein, before the message server streams the digital audio file to the client terminal, the message server authenticates the user.

5. A method as claimed in claim 1, wherein the data network is a local area network.

6. A method as claimed in claim 1, wherein the data network is a packet switched network, and wherein streaming the digital audio file over the data network to the client terminal comprises transmitting packets representative of the digital audio file over the data network.

7. A method as claimed in claim 6, wherein the data network is a TCP/IP network.

8. A method as claimed in claim 6, wherein the data network is an intranet.

9. A method as claimed in claim 6, wherein the data network is the Internet.

10. A method as claimed in claim 6, wherein the client terminal is coupled with said data network via a point-to-point protocol.

11. A method as claimed in claim 1, further comprising the client terminal operating a streaming-player application adapted to receive and play streamed digital audio files, the streaming-player application providing the plurality of streaming controls.

12. A method of transcribing a voice signal, the method comprising, in combination:

recording the voice signal on a storage medium accessible over a data network, the data network including a message server adapted to stream the voice signal to a client terminal over the data network, the client terminal adapted to receive the voice signal and providing a plurality of controls to enable a user at the client terminal to selectively play, stop and rewind the voice signal;

sending from the client terminal to the server a request to begin streaming the voice signal to the client terminal;

responsive to the request, the message server beginning to stream the voice signal to the client terminal for transcription by the user; and

the user operating the controls and selectively listening to and transcribing the voice signal as the voice signal is being streamed over the network to the client terminal;

wherein the server may pause and stop streaming of the voice signal to the client terminal in response to instructions provided from the client terminal.

13. A method as claimed in claim 12, wherein, before the message server streams the voice signal to the client terminal, the message server authenticates the user.

14. A method as claimed in claim 12, wherein the data network is a local area network.

15. A method as claimed in claim 12, wherein the data network is a packet switched network, and wherein streaming the voice signal to the client terminal comprises transmitting packets representative of the voice signal.

16. A method as claimed in claim 15, wherein the data network is a TCP/IP network.

17. A method as claimed in claim 15, wherein the data network is an intranet.

18. A method as claimed in claim 15, wherein the data network is the Internet.

19. A method as claimed in claim 15, wherein the client terminal communicates with the data network via a point-to-point protocol.

20. A method as claimed in claim 12, wherein recording the voice signal on the storage medium comprises recording the voice signal in a digital format, and wherein the client terminal is a digital computer operating a streaming-player application adapted to receive and play streamed audio signals, the streaming-player application providing said controls.

21. A system for providing network based transcription of a voice signal comprising, in combination:

a file store;

a server in a data network, the server being coupled with the file store, and the server receiving a first digital audio file representative of the voice signal and storing the first digital audio file in the file store;

a client terminal in the data network, the client terminal adapted to receive streamed digital audio files from the data network and including a plurality of streaming controls to enable a user at the client terminal to selectively play the digital audio files;

the server further adapted to receive a request from the client terminal to stream the first digital audio file over the data network to the client terminal, and, responsive to the request, said server beginning to stream the first digital audio file over the data network to the client terminal;

wherein, as the streamed digital audio file arrives at the client terminal, (i) the client terminal receives the digital audio file and audibly plays the voice signal represented by the digital audio file, and (ii) a user at the client terminal transcribes the voice signal audibly played by the client terminal; and

wherein, the server may pause and stop streaming of the voice signal to the client terminal in response to instructions provided from the client terminal.

22. A system as claimed in claim 21, wherein the voice signal received by the server originates from a person providing a verbal response to a voice prompt.

23. A system as claimed in claim 22, wherein the voice prompt is associated with a promotional survey.

24. A system as claimed in claim 21, wherein the server receives the voice signal from a network voice capture device.

25. A system as claimed in claim 24, wherein the network voice capture device receives the voice signal from a subscriber device.

26. A system as claimed in claim 25, wherein the subscriber device is selected from the group consisting of a telephone and a computer.

27. A system as claimed in claim 21, wherein the client terminal is a digital computer operating a streaming-player application adapted to receive and play the voice signal, the streaming-player application providing the controls.

28. A system as claimed in claim 21, wherein the data network is a local area network.

29. A system as claimed in claim 21, wherein the data network is an intranet.

30. A system as claimed in claim 21, wherein the data network is the Internet.

31. A system as claimed in claim 21, wherein the data network is a packet switched network.
