Abstract

A method of obtaining video content is disclosed and includes receiving a spoken search, determining each word in the spoken search in a word-sensitive context, generating a first plurality of hypothetical search strings, and searching a text-based video content library index with the first plurality of hypothetical search strings. Further, the method includes determining whether any video content titles within the text-based video content library index match each of the first plurality of hypothetical search strings and transmitting a first plurality of matching video content titles to an intelligent media center.

Claims

1. A method of obtaining video content, comprising:

receiving a spoken search;

determining each word in the spoken search in a word-sensitive context;

generating a first plurality of hypothetical search strings;

searching a text-based video content library index with the first plurality of hypothetical search strings;

determining whether any video content titles within the text-based video content library index match each of the first plurality of hypothetical search strings; and

transmitting a first plurality of matching video content titles to an intelligent media center.

2. The method of claim 1, further comprising indicating to the intelligent media center that no matching video content titles exist.

3. The method of claim 1, further comprising generating a word graph in real-time from the spoken search.

4. The method of claim 3, transmitting the word graph to the intelligent media center.

5. The method of claim 1, further comprising generating a list of matching video content titles corresponding to the first plurality of matching video content titles, wherein the list of matching video content titles includes each of the first plurality of matching video content titles, a rating of each of the first plurality of matching video content titles, a viewing duration of each of the first plurality of matching video content titles, and a summary description of each of the first plurality of matching video content titles.

6. The method of claim 5, wherein the summary description of each of the first plurality of matching video content titles includes at least one matching word from the spoken search and at least two words surrounding the matching word.

7. The method of claim 1, further comprising:

receiving a spoken clarification associated with the spoken search;

concatenating the spoken clarification with the spoken search;

generating a second plurality of hypothetical search strings based on the spoken search and the spoken clarification;

searching the text-based video content library index with the second plurality of hypothetical search strings;

determining whether any video content titles within the text-based video content library index match the second plurality of hypothetical search strings; and

transmitting a second plurality of matching video content titles to the intelligent media center.

8. The method of claim 1, further comprising:

determining a storage category for each of the first plurality of matching video content titles;

determining a dominant storage category for the first plurality of matching video content titles, wherein the dominant storage category is a storage category that is determined to be associated with most of the first plurality of matching video content titles; and

transmitting a video advertisement to the intelligent media center, wherein the video advertisement is associated with the dominant storage category.

9. The method of claim 8, wherein the video advertisement is further associated with an advertising customer that has submitted a highest advertising bid for the dominant storage category.

10. A method of obtaining video content, comprising:

receiving a spoken search from a wireless access terminal;

transmitting the spoken search to a server over a network;

receiving a plurality of matching video content titles from the server; and

comparing the plurality of matching video content titles to a locally stored search history.

11. The method of claim 10, further comprising selecting a plurality of most likely matching video content titles based on the locally stored search history.

12. The method of claim 11, further comprising creating a menu of most likely matching video content titles.

13. The method of claim 12, further comprising transmitting the menu of most likely matching video content titles to an Internet protocol television.

14. The method of claim 13, further comprising:

receiving a user selection of a selected title from the plurality of most likely matching video content titles; and

storing the selected title within the locally stored search history.

15. The method of claim 14, further comprising:

transmitting the selected title to the server;

receiving video content associated with the selected title; and

transmitting the video content to the Internet protocol television.

16. A system, comprising:

a video content library database storing a plurality of video content titles;

a video content library index including a text title associated with each of the plurality of video content titles stored within the video content library database and including a text description of each of the plurality of video content titles; and

a server coupled to the video content library database and coupled to the video content library index, the server comprising;

a processor;

a computer readable medium accessible to the processor; and

a computer program embedded within the computer readable medium, the computer program comprising;

instructions to receive a spoken search;

instructions to generate a first plurality of search strings from the spoken search; and

instructions to search the video content library index based on the first plurality of search strings to locate one or more matching video content titles.

17. The system of claim 16, wherein the computer program further comprises instructions to generate a first real-time word graph derived from the spoken search.

18. The system of claim 17, wherein the computer program further comprises instructions to transmit the real-time word graph to a remote device.

19. The system of claim 16, wherein the computer program further comprises:

instructions to receive a spoken clarification associated with the spoken search;

instructions to concatenate the spoken clarification and the spoken search;

instructions to generate a second plurality of search strings based on the spoken search and the spoken clarification; and

instructions to search the video content library index with the second plurality of search strings.

20. The system of claim 19, wherein the computer program further comprises instructions to generate a second real-time word graph based on the spoken search and the spoken clarification.

21. A portable electronic device comprising:

a microphone;

a talk button;

a processor;

a computer readable medium accessible to the processor; and

a computer program embedded within the computer readable medium, the computer program comprising;

a speech input agent; and

a distributed speech recognition front-end, wherein the speech input agent is activated in response to a selection of the talk button and wherein the speech input agent uses the distributed speech recognition front-end to record speech input received by the microphone in a high fidelity mode.

22. The device of claim 21, wherein the distributed speech recognition front-end extracts one or more acoustic features from recorded speech.

23. The device of claim 22, wherein the distributed speech recognition front-end extracts one or more phonetic features from recorded speech.

24. The device of claim 23, wherein the distributed speech recognition front-end compresses recorded speech.

25. The device of claim 24, wherein the distributed speech recognition front-end transmits compressed speech in real-time to a distributed speech recognition network.

26. The device of claim 25, wherein the compressed speech is transmitted via an intelligent media center.

27. The device of claim 26, wherein the device is a wireless access terminal having wireless fidelity capability.

28. The device of claim 26, wherein the device is a portable digital assistant having wireless fidelity capability.

29. The device of claim 26, wherein the device is a mobile telephone having wireless fidelity capability.
