Abstract

A method for speech recognition of an alphabet including receiving an audio input including at least one letter of an alphabet and at least one word, recognizing the letter of an alphabet and the word in the audio input; and mapping the word to the letter.

Claims

1. A method for speech recognition of an alphabet comprising:

receiving an audio input including at least one letter of an alphabet and at least one word;

recognizing said at least one letter of an alphabet and said at least one word in said audio input; and

mapping said at least one word to said at least one letter.

2. A method according to

claim 1

and wherein said audio input is received via a telephone.

3. A method according to

claim 1

and wherein said audio input is received via a microphone.

4. A method according to

claim 1

and wherein said at least one word is selected from a set of names.

5. A method according to

claim 1

and wherein said at least one word is selected from a set of names of fruits.

6. A method according to

claim 1

and also comprising providing an audio feedback of letters of an alphabet to which recognized words are mapped.

7. A method according to

claim 1

and also comprising combining a plurality of said at least one letters into a target word.

8. A method according to

claim 7

and also comprising annunciating said target word to a user.

9. A method according to

claim 8

and wherein said annunciating includes annunciating said target word prior to mapping of all of the letters making up said target word.

10. A method according to

claim 1

and wherein said mapping comprises matching the first letter of said at least one word to said at least one letter.

11. A method for speech recognition of an alphabet comprising:

receiving an audio input including at least one target word made up of a plurality of letters in an alphabet and at least one auxiliary word corresponding to each of said plurality of letters;

recognizing said plurality of auxiliary words in said audio input;

mapping each of said plurality of auxiliary words to a corresponding one of said plurality of letters; and

composing said target word from said plurality of letters.

12. A method according to

claim 11

and wherein said audio input is received via a telephone.

13. A method according to

claim 11

and wherein said audio input is received via a microphone.

14. A method according to

claim 11

and wherein said plurality of auxiliary words is selected from a set of names.

15. A method according to

claim 11

and wherein said plurality of auxiliary words is selected from a set of names of fruits.

16. A method according to

claim 11

and also comprising providing an audio feedback of letters of said alphabet to which recognized auxiliary words are mapped.

17. A method according to

claim 11

and wherein said composing comprises combining said plurality of said at least one letters in the order recognized into said target word.

18. A method according to

claim 17

and also comprising annunciating said target word to a user.

19. A method according to

claim 18

and wherein said annunciating includes annunciating said target word prior to mapping of all of the letters making up said target word.

20. A method according to

claim 11

and wherein said mapping comprises matching the first letter of each of said plurality of auxiliary words to said at least one letter.

21. A system for speech recognition of an alphabet comprising:

a receiver, receiving an audio input including at least one letter of an alphabet and at least one word;

a recognizer, recognizing said at least one letter of an alphabet and said at least one word in said audio input; and

a mapper, mapping said at least one word to said at least one letter.

22. A system according to

claim 21

and wherein said audio input is received via a telephone.

23. A system according to

claim 21

and wherein said audio input is received via a microphone.

24. A system according to

claim 21

and wherein said at least one word is selected from a set of names.

25. A system according to

claim 21

and wherein said at least one word is selected from a set of names of fruits.

26. A system according to

claim 21

and also comprising an audio output generator providing an audio feedback of letters of an alphabet to which recognized words are mapped.

27. A system according to

claim 21

and also comprising a word generator combining a plurality of said at least one letters into a target word.

28. A system according to

claim 27

and also comprising an annunciator, annunciating said target word to a user.

29. A system according to

claim 28

and wherein said annunciator is operative to annunciate said target word prior to mapping of all of the letters making up said target word.

30. A system according to

claim 21

and wherein said mapper is operative to match the first letter of said at least one word to said at least one letter.

31. A system for speech recognition of an alphabet comprising:

a receiver, receiving an audio input including at least one target word made up of a plurality of letters in an alphabet and at least one auxiliary word corresponding to each of said plurality of letters;

a recognizer, recognizing said plurality of auxiliary words in said audio input;

a mapper, mapping each of said plurality of auxiliary words to a corresponding one of said plurality of letters; and

a target word generator composing said target word from said plurality of letters.

32. A system according to

claim 31

and wherein said audio input is received via a telephone.

33. A system according to

claim 31

and wherein said audio input is received via a microphone.

34. A system according to

claim 31

and wherein said plurality of auxiliary words is selected from a set of names.

35. A system according to

claim 31

and wherein said plurality of auxiliary words is selected from a set of names of fruits.

36. A system according to

claim 31

and also comprising an audio feedback generator, providing an audio feedback of letters of said alphabet to which recognized auxiliary words are mapped.

37. A system according to

claim 31

and wherein said target word generator is operative to combine said plurality of said at least one letters in the order recognized into said target word.
