Abstract

Disclosed are editing methods that are added to speech-based searching to allow users to better understand textual queries submitted to a search engine and to easily edit their speech queries. According to some embodiments, the user begins to speak. The user'"'"'s speech is translated into a textual query and submitted to a search engine. The results of the search are presented to the user. As the user continues to speak, the user'"'"'s speech query is refined based on the user'"'"'s further speech. The refined speech query is converted to a textual query which is again submitted to the search engine. The refined results are presented to the user. This process continues as long as the user continues to refine the query. Some embodiments present the textual query to the user and allow the user to use both speech-based and non-speech-based tools to edit the textual query.

Claims

1. A method for progressively refining a speech-based search, the method comprising:

receiving initial speech input from a user;

performing a search, the search based, at least in part, on the initial speech input;

presenting at least some results of the search to the user; and

as the user continues to speak, refining the search based, at least in part, on further speech input received from the user and presenting at least some refined search results to the user.

2. The method of claim 1 wherein performing a search comprises extracting one or more search terms from the initial speech input and extracting one or more search terms from the further speech input.

3. The method of claim 2 wherein presenting at least some results of the search comprises selecting results to present, the selecting based, at least in part, on ranking by confidence the extracted search terms.

4. The method of claim 2 further comprising:

presenting at least some extracted search terms to the user.

5. The method of claim 4 wherein presenting at least some extracted search terms to the user comprises marking search terms that are assigned a higher confidence.

6. The method of claim 2 wherein refining the search comprises:

assigning a higher confidence in the search to a search term extracted from the further speech input than a confidence assigned to a search term extracted from the initial speech input.

7. The method of claim 2 wherein refining the search comprises:

assigning a higher confidence in the search to a repeated extracted search term than to a non-repeated extracted search term.

8. The method of claim 2 wherein refining the search comprises:

assigning a lower confidence to a search term extracted from early in the speech input received from the user.

9. The method of claim 1 wherein refining the search comprises:

performing a new search, the new search based, at least in part, on the initial speech input and on the further speech input received from the user.

10. A method for refining a speech-based search, the method comprising:

receiving speech input from a user;

extracting one or more search terms from the received speech input;

performing a search, the search based, at least in part, on the extracted search terms;

presenting at least some results of the search to the user;

presenting at least some extracted search terms to the user;

receiving a command from the user to logically manipulate the presented search terms;

refining the search, the refining based, at least in part, on the logical manipulation command received from the user; and

presenting at least some refined search results to the user.

11. The method of claim 10 wherein presenting at least some results of the search comprises selecting results to present, the selecting based, at least in part, on ranking by confidence the extracted search terms.

12. The method of claim 10 wherein presenting at least some extracted search terms to the user comprises marking search terms that are assigned a higher confidence.

13. The method of claim 10 wherein receiving a command from the user comprises receiving an element from the group consisting of:

tactile input, keyed input, gestural input, and speech input.

14. The method of claim 10 wherein the command to logically manipulate the presented search terms comprises an element selected from the group consisting of:

remove a search term from consideration, change a confidence level of a search term, combine a plurality of search terms into a search phrase, create a logical disjunction of search terms, create a logical conjunction of search terms, and change a logical precedence within a search string.

15. The method of claim 10 wherein refining the search comprises:

performing a new search, the new search based, at least in part, on the logical manipulation command received from the user.

16. A personal communication device comprising:

a microphone configured for receiving speech input from a user;

an output device; and

a processor operatively connected to the microphone and to the output device, the processor configured for performing a search, the search based, at least in part, on initial speech input received from the user, for presenting on the output device at least some results of the search to the user, and, as the user continues to speak, for refining the search based, at least in part, on further speech input received from the user and for presenting on the output device at least some refined search results to the user.

17. The personal communication device of claim 16 wherein the output device is selected from the group consisting of:

a speaker and a display screen.

18. The personal communication device of claim 16 further comprising:

a transceiver operatively connected to the processor;

wherein performing a search comprises transmitting a search query to a remote device and receiving search results from the remote device.

19. A personal communication device comprising:

a microphone configured for receiving speech input from a user;

an input device;

an output device; and

a processor operatively connected to the microphone, to the input device, and to the output device, the processor configured for extracting one or more search terms from speech input received from the user, for performing a search, the search based, at least in part, on the extracted search terms, for presenting on the output device at least some results of the search to the user, for presenting on the output device at least some extracted search terms to the user, for receiving on the input device a command from the user to logically manipulate the presented search terms, for refining the search, the refining based, at least in part, on the logical manipulation command received from the user, and for presenting on the output device at least some refined search results to the user.

20. The personal communication device of claim 19 wherein the input device is selected from the group consisting of:

the microphone, a keypad, and a graphical user interface.

21. The personal communication device of claim 19 wherein the output device is selected from the group consisting of:

a speaker and a display screen.

22. The personal communication device of claim 19 further comprising:

a transceiver operatively connected to the processor;

wherein performing a search comprises transmitting a search query to a remote device and receiving search results from the remote device.
