Abstract

A method for utilizing oral movements is used in speech assessment, speech therapy, language development, and controlling external devices. A device is used which includes a sensor plate having sensors to detect contact of the tongue with the sensor plate. One aspect of the invention allows viewing representations of contact of the tongue and palate during speech and comparing the representations with model representations displayed in a split screen fashion. The model representations may be generated by another speaker utilizing a sensor plate or by computer generated representations which have been electronically stored. The representations may be analyzed to assess speech proficiency and the model may be mimicked for speech enhancement.

Claims

1. A method for providing speech therapy comprising:

(A) displaying a model representation of a position of contact between a model tongue and mouth during speech;

(B) displaying a representation of a position of contact between a learner'"'"'s tongue and mouth during speech;

(C) displaying a model representation of a contact between a model lip and teeth during speech; and

(D) representing the position of contact between the learner'"'"'s tongue and mouth during speech by a grid of dots on a computer screen, wherein said dots expand and change color responsive to contact between the learner'"'"'s tongue and mouth.

2. The method of claim 1 further comprising instructing the learner to mimic the model representation of the position of contact between the model tongue and mouth during speech.

3. The method of claim 2 further comprising the step of comparing the representation of the position of contact between the learner'"'"'s tongue and mouth during speech with the model representation of position of contact between the model tongue and mouth during speech.

4. The method of claim 2 further comprising the step of generating a numerical score representing the closeness of fit between the representation of position of contact between the learner'"'"'s tongue and mouth during speech and the model representation of position of contact between the model tongue and mouth during speech.

5. The method of claim 2 further comprising the step of providing positive reinforcement when the learner mimics the model representation of position of contact between the model tongue and mouth during speech.

6. The method of claim 5 wherein the positive reinforcement comprises computer generated congratulations.

7. The method of claim 5 wherein the positive reinforcement comprises dynamic displays on a computer monitor.

8. The method of claim 2 further comprising the step of providing model acoustic representations of the speech.

9. The method of claim 8 wherein auditory mimicry accuracy between the learner and the model acoustic representation are analyzed acoustically.

10. The method of claim 9 wherein a numerical score representing the closeness of acoustic fit is generated.

11. The method of claim 8 wherein sound spectrographic displays are generated from the model acoustic representation and the learner'"'"'s speech.

12. The method of claim 2 wherein the model representation is designed to exercise the learner'"'"'s tongue when the learner mimics the model representation.

13. The method of claim 2 wherein the model representation is designed to instruct the learner to compensate for physical deficiencies.

14. The method of claim 1 wherein the representations of position of contact between the learner'"'"'s tongue and mouth during speech and the model representations of position of contact between the model tongue and mouth during speech are displayed on a split-screen.

15. The method of claim 1 wherein the learner is unable to overcome speech disorders through traditional auditory based therapy.

16. The method of claim 1 wherein the learner has severe to profound hearing loss.

17. The method of claim 1 wherein the learner has stroke-limited ability to control tongue movement and placement.

18. The method of claim 1 wherein the learner has limited high frequency sound perception which causes lisping.

19. The method of claim 1 wherein the learner has reduced ability to build up pressure in the mouth.

20. The method of claim 1 wherein the learner has physical abnormalities affecting the mouth and vocal tract.

21. The method of claim 1 wherein the learner has limited energy to devote to speech activity.

22. The method of claim 1 wherein the learner is learning new speech patterns after cochlear implant surgery.

23. The method of claim 1 wherein the learner has gradually deteriorating hearing loss and needs assistance to maintain speech articulation skills.

24. The method of claim 1 wherein the learner is learning a speech pattern selected from the group consisting of a foreign language and a dialect.

25. The method of claim 1 wherein the grid of dots corresponds to sensors disposed on a sensor plate which is custom fitted in the mouth of the learner.

26. The method of claim 1 wherein the speech includes sounds, words, phrases or sentences, and wherein the sounds, words, phrases, or sentences are displayed in writing.

27. The method of claim 1 wherein the position of contact between the learner'"'"'s tongue and mouth during speech is recorded.

28. The method of claim 27 wherein the learner'"'"'s speech is recorded acoustically corresponding to the position of contact between the learner'"'"'s tongue and mouth during speech.

29. The method of claim 27 wherein the model representation is recorded.

30. The method of claim 1 wherein the model representation is generated by a model speaker.

31. The method of claim 30 wherein the model speaker is representative of a particular age group, gender, or language type.

32. The method of claim 1 further comprising:

(E) displaying a representation of a contact between a learner'"'"'s lip and teeth during speech.

33. A method for providing speech therapy comprising:

(A) displaying a model representation of a position of contact between a model tongue and mouth during speech;

(B) displaying a representation of a position of contact between a learner'"'"'s tongue and mouth during speech;

(C) instructing the learner to mimic the model representation of the position of contact between the model tongue and mouth during speech;

(D) comparing the representation of the position of contact between the learner'"'"'s tongue and mouth during speech with the model representation of position of contact between the model tongue and mouth during speech;

(E) generating a numerical score representing the closeness of fit between the representation of position of contact between the learner'"'"'s tongue and mouth during speech and the model representation of position of contact between the model tongue and mouth during speech;

(F) providing positive reinforcement when the learner mimics the model representation of position of contact between the model tongue and mouth during speech; and

(G) providing model acoustic representations of the speech;

wherein the representations of position of contact between the learner'"'"'s tongue and mouth during speech and the model representations of position of contact between the model tongue and mouth during speech are displayed on a split-screen;

wherein auditory mimicry accuracy between the learner and the model acoustic representation are analyzed acoustically;

wherein a numerical score representing the closeness of acoustic fit is generated;

wherein sound spectrographic displays are generated from the model acoustic representation and the learner'"'"'s speech;

wherein the position of contact between the learner'"'"'s tongue and mouth during speech is represented by a grid of dots on said split-screen, said dots expand and change color corresponding to contact between the learner'"'"'s tongue and mouth;
