Abstract

Methods and related computer program products, systems, and devices for providing feedback to a user based on audio input associated with a user reading a passage from a physical text are disclosed.

Claims

1. A method comprising;

receiving audio input associated with a user reading a sequence of words from a physical text; and

comparing at least a portion of the received audio input to stored information about the locations of words in the physical text to determine a location from which the user is reading.

2. The method of claim 1, wherein the information about the locations of words in the physical text comprises an electronic file having foreknowledge of the words from the physical text.

3. The method of claim 2, further comprising receiving an electronic file.

4. The method of claim 3, wherein

the physical text comprises a book;

and

receiving the electronic file comprises receiving the electronic file from a publisher of the book.

5. The method of claim 2, wherein comparing the received audio input to words in an electronic file comprises matching a sequence of words in the electronic file to a sequence of words in the audio input to generate a matched sequence.

6. The method of claim 5, further comprising determining if the matched sequence occurs at more than one location in the physical text.

7. The method of claim 6, further comprising comparing additional words from the audio input to the words in the electronic file if the matched sequence occurs at more than one location in the electronic file.

8. The method of claim 1, wherein matching a sequence of words comprises determining if one or more words in the sequence of words is included in a set of non-indexed words and matching only the words in the audio input that are not included in the set of non-indexed words,

9. The method of claim 2, further comprising determining a number of words in the audio input and matching the sequence of words only if the number of words in the audio input is greater than a predetermined threshold.

10. The method of claim 9, wherein the physical text includes at least some indexed words and at least some non-indexed words and the number of words comprises a number of indexed words.

11. The method of claim 1, wherein comparing the at least a portion of the received audio input to the stored information about the locations of words in the physical text to determine the location from which the user is reading comprises;

matching a minimum sequence of words in the input file to a words in the electronic file to generate one or more matched sequences; and

determining if the one or more matched sequences satisfy a minimum probability threshold.

12. The method of claim 1, wherein comparing the at least a portion of the received audio input to the stored information about the locations of words in the physical text to determine the location from which the user is reading comprises:

matching a first word in the input file to a word that occurs one or more times in the electronic file;

determining if a second word in the input file matches a word subsequent to the first matched word in the electronic file; and

determining if a third word in the input file matches a word subsequent to the first matched word and subsequent to the second word in the electronic file.

13. A computer program product, tangibly embodied in an information carrier, for executing instructions on a processor, the computer program product being operable to cause a machine to:

receive audio input associated with a user reading a sequence of words from a physical text;

compare at least a portion of the received audio input to stored information about the locations of words in the physical text to determine a location from which the user is reading.

14. The computer program product of claim 13, wherein the information about the locations of words in the physical text comprises an electronic file having foreknowledge of the words from the physical text.

15. The computer program product of claim 13, wherein

the physical text comprises a book and the computer program product is further configured to cause the machine to receive the electronic file comprises receiving the electronic file from a publisher of the book.

16. The computer program product of claim 13, wherein the computer program product is operable to cause the machine to determining a number of words in the audio input and match the sequence of words only if the number of words in the audio input is greater than a predetermined threshold.

17. The computer program product of claim 13, wherein the computer program product is operable to cause the machine to:

match a first word in the input file to a word that occurs one or more times in the electronic file;

determine if a second word in the input file matches a word subsequent to the first matched word in the electronic file; and

determine if a third word in the input file matches a word subsequent to the first matched word and subsequent to the second word in the electronic file.

18. A system comprising:

a memory having an electronic file with information about a sequence of words in a physical text stored thereon; and

a processor configured to;

receive audio input associated with a user reading a sequence of words from a physical text;

compare at least a portion of the received audio input to stored information about the locations of words in the physical text to determine a location from which the user is reading.

19. The system of claim 18, wherein the information about the locations of words in the physical text comprises an electronic file having foreknowledge of the words from the physical text.
