Abstract

A portable voice or speech aid enabling a deaf or voice impaired user to make sounds into a microphone to output intelligible speech through a built-in speaker or to a text display screen.

Claims

1. An apparatus, comprising:

a microphone used to receive unintelligible voice utterances from a deaf or voice-impaired person;

a voice-word-profile containing representations of said voice unintelligible utterances and corresponding correct speech patterns;

a sound recognition routine to match said unintelligible voice utterances to said correct speech patterns; and

a speaker to output said correct speech patterns matched by said sound recognition routine,

so that said apparatus corrects unintelligible speech patterns enabling a deaf or voice-impaired person to communicate in correct speech patterns by uttering otherwise unrecognizable speech pattern.

2. An apparatus as claimed in claim 1 further comprising a text display to output said correct speech patterns from said voice-word profile.

3. An apparatus as claimed in claim 1 wherein said apparatus further comprises an emergency alarm with controllable volume activated by said deaf or voice-impaired person.

4. An apparatus as claimed in claim 1 further comprising a modem for connection to a telephone to output said correct speech patterns, or to receive said voice utterances

5. An apparatus as claimed in claim 1 further comprising a connection for stationary computer to allow updating of said voice-wordprofile, said stationary computer comprising:

a display;

a keyboard; and

memory and data storage capability.

6. An apparatus as claimed in claim 1 further comprising a speech card which converts said correct speech patterns to electronic signals capable of being output on said speaker and enabling said deaf or voice-impaired person to adjust speaker pitch, volume, and tone.

7. An apparatus as claimed in claim 1 wherein said microphone is attachable around said deaf or voice impaired person'"'"'s neck.

8. An apparatus as claimed in claim 1 wherein said "voice-word profile" is contained on a removable diskette.

9. An apparatus as claimed in claim 1 which is pocket sized.

10. An apparatus as claimed in claim 1 wherein when said voice utterance does not match a correct speech pattern, said sound recognition routine is programmed to perform one of the following

continue to accept a next voice utterance,

notify said deaf or voice-impaired person of an error and accept a next voice utterance,

prompt said deaf or voice-impaired person to repeat the unrecognized utterance until a user defined maximum number of times occur, or

match to a correct speech pattern by allowing said deaf or voice-impaired person to vocalize an utterance corresponding to a spelling of a correct speech pattern.

11. An apparatus as claimed in claim 1 wherein said sound recognition routine identifies words with identical sounds but different spellings by a predetermined different voice utterance for each word.

12. An apparatus as claimed in claim 1 further comprising means for executing a vocalization learning routine to create additional voice-word profiles and to update said voice-word-profile by prompting said deaf or voice-impaired person to identify words and their spellings.

13. An apparatus as claimed in claim 12 further comprising:

a spelling dictionary

a spell mode routine using said spelling dictionary to allow said sound recognition routine to identify unrecognized words not contained in said spelling dictionary and to allow said vocalization learning routine to update said voice-word-profile by spelling words which are to be added to said voice-word-profile.

14. An apparatus as claimed in claim 1 further comprising additional voice-word-profiles wherein said sound recognition routine matches said voice utterances of each deaf or voice-impaired person to said corresponding correct speech pattern in each respective one of said additional voice-word-profiles.

15. An apparatus, comprising:

means for receiving unrecognizable voice utterances intended as communicative speech from deaf or voice impaired persons and comparing said utterances to stored representations of said utterances, said stored representations being associated with correspondign words;

means for identifying a match between one of said utterances and one of said stored representations of utterances, and outputting the word corresponding to the identified representation; and

means for vocalizing said word corresponding to said identified representation so that said utterances of a deaf or voice-impaired person intended as communicative speech are output in a correct speech pattern to make them understandable.

16. A method, comprising:

storing a voice-word-profile containign representations of unintelligible voice utterances of a deaf or voice-impaired person and a correct speech pattern corresponding to each voice utterance;

receiving voice utterances from said deaf or voice-impaired person;

matching said voice utterances to said correct speech patterns;

outputting said correct speech patterns to an output device where it is vocalized,

so that utterances of a deaf or voice-impaired person intended as communicative speech are output in a correct speech pattern to make them understandable.

17. A method, comprising:

receiving unrecognizable voice utterances intended as communicative speech from a deaf or voice impaired person and comparing said utterances to stored representations of utterances, said stored representations being associated with corresponding words;

identifying a match between one of said utterances and oen of said stored representations of utterances, and outputting the word corresponding to the identified representation; and

vocalizing said word corresponding to said identified representation so that said utterances of a deaf or voice-imparied person intended as communicative speech are output in a correct speech pattern to make them understandable.

18. A method as set forth in claim 17 wherein said display is an aural display.

19. A method as set forth in claim 17 wherein said display is a visual display
