Abstract

The present invention provides a method for analyzing reading skills comprised of recording and digitizing sound waves generated by a subject'"'"'s voice in response to a series of stimuli. The sound waves are decomposed into sequences of articulation and pause periods. The articulation and pause periods are determined by first scanning the generated sound waves and identifying locations along the sound waves where the sound amplitude raises above or drops bellow a given value. The reading ability of the subject is profiled by analyzing the series of pause and/or articulation periods. The method allows for the diagnosis of reading deficiencies. Based on the diagnosed deficiencies in the subject'"'"'s reading skills, drill exercises are proposed and rounds of testing and drill exercising are repeated until the diagnosed reading deficiencies are corrected. The method is particularly suitable for use in conjunction with computerized equipment. A particular type of tests used in conjunction with this invention is the Reading Automatized Naming test (R.A.N.). The method and device of this application comprise presenting a subject with a set of R.A.N.

Claims

1. A method for analyzing reading and attention skills, comprising:

providing a series of naming elements;

detecting a response as a user reads the naming elements; and

determining the duration of pauses in the response.

2. The method of claim 1 wherein the naming elements are arranged in epochs, and further comprising determining the variance of total pause duration between epochs.

3. The method of claim 1 further comprising providing suggested activities for addressing the variance.

4. The method of claim 1 further comprising providing a second series of naming elements after the pause time is less than a given value.

5. The method of claim 1 further comprising comparing the detected response to an expected response.

6. A method for analyzing reading and attentional skills comprised of:

detecting sound waves generated by a subject'"'"'s voice in response to a series of stimuli;

wherein the digitized sound waves are characterized by sets of points, each point having a time coordinate and a sound amplitude coordinate;

determining articulation and pause periods wherein each articulation period is defined by an articulation onset point and an articulation offset point; and

each pause period is defined by a pause onset point and a pause offset point; and

analyzing the sequence of articulation and pause periods.

7. The method of claim 6 wherein articulation onset points are set along the sound waves at points where wave amplitude increases to exceed a given first value, and articulation offset points are set along the sound waves at points where wave amplitude drops below a given second value.

8. The method of claim 7 wherein determination of articulation and/or pause periods comprises manipulation of one or more time coordinates.

9. The method of claim 7 wherein for each set of first and second articulation onset points separated by an articulation offset point, pause periods are determined by subtracting the time coordinate of the articulation offset point from the time coordinate of the second articulation onset point.

10. The method of claim 6 wherein pause onset points are set along the sound waves at points where wave amplitude drops below a given first value, and pause offset points are set along the sound waves at points where wave amplitude increases to exceed a given second value.

11. The method of claim 10 wherein for each set of first and second pause onset points separated by a pause offset point, pause periods are determined by subtracting the time coordinate of the first pause onset point from the time coordinate of the pause offset point.

12. The method of claim 10 wherein for each set of first and second pause onset points separated by a pause offset point, articulation periods are determined by subtracting the time coordinate of the pause offset point from the time coordinate of the second pause onset point.

13. The method of claim 6 further comprised of determining a mean noise level associated with the sound waves and setting the mean noise level as the zero point of the sound wave amplitude scale.

14. The method of claims 9 and 11 further comprised of analyzing pause periods and determining the subject'"'"'s reading profile, the profile comprising a number of indicators characterizing reading and attentional deficiencies in the subject'"'"' response to one or more stimuli.

15. The method of claim 14 further comprised of providing the subject with letter retrieval, recognition, and articulation drill exercises to correct the reading deficiencies.

16. The method of claims 8 and 12 further comprised of analyzing articulation periods and determining the subject'"'"'s reading profile, the profile comprising a number of indicators characterizing diagnosed reading deficiencies in the subject'"'"'s reading skills.

17. The method of claim 16 further comprised of providing the subject with letter retrieval, recognition, and articulation drill exercises to correct the diagnosed reading deficiencies.

18. The method of claim 6 wherein articulation onset points are set along the sound waves at points where wave amplitude increases to exceed a given first value for at least a first given duration, and articulation offset points are set along the sound waves at points where wave amplitude drops below a given second value for at least a second given duration.

19. The method of claim 6 wherein pause onset points are set along the sound waves at points where wave amplitude drops below a given first value for at least a first given duration, and pause offset points are set along the sound waves at points where wave amplitude increases to exceed a given second value for at least a second given duration.

20. The method of claim 6 wherein the stimuli are sub-tests selected from an R.A.N. battery of reading tests.

21. A method for analyzing reading and attentional skills, comprising:

providing a series of naming elements;

detecting a response as a user reads the naming elements; and

analyzing the frequencies of the responses.
