Abstract

A method and apparatus for diagnosing a user'"'"'s health state are provided. The apparatus includes including a voice detecting unit which detects and monitors a user'"'"'s voice; a voice analyzing unit which extracts a voice feature from a voice detected by the voice detecting unit, based on a health state to be diagnosed; a voice diagnosing unit which diagnoses a health state of the user by comparing the voice feature extracted by the voice analyzing unit with an abnormal state reference, and which monitors a change in the health state; and a diagnosis outputting unit which outputs information regarding the health state and a health state change diagnosed by the voice diagnosing unit.

Claims

1. A health diagnosing apparatus comprising:

a voice detecting unit configured to detect a user'"'"'s voice;

a voice analyzing unit configured to extract a voice feature from the user'"'"'s voice detected by the voice detecting unit;

a voice diagnosing unit configured to diagnose the user'"'"'s voice by comparing the voice feature extracted by the voice analyzing unit with reference;

a warning outputting unit configured to output a predetermined warning indication based on a result of diagnosing.

2. The health diagnosing apparatus of claim 1, wherein the voice detecting unit is further configured to monitor changes in a voice state of the user.

3. The health diagnosing apparatus of claim 1, wherein the voice detecting unit comprises:

an analog-to-digital converter,

wherein the voice detecting unit is further configured to detect a voice signal from a digital signal output by the analog-to-digital converter.

4. The health diagnosing apparatus of claim 1, wherein the voice analyzing unit comprises:

a health state selecting unit configured to select a health state type to be diagnosed based on the user'"'"'s voice detected by the voice detecting unit

a voice period selecting unit configured to select a voice period for a diagnosis based on the health state type selected by the health state selecting unit; and

a voice feature selecting unit configured to select the voice feature according to the health state type selected by the health state selecting unit; and

a voice feature extracting unit configured to extract the voice feature from the user'"'"'s voice based on the voice feature selected by the voice feature selecting unit.

5. The health diagnosing apparatus of claim 4, wherein the voice feature extracting unit comprises a normal voice database and an abnormal voice database.

6. The health diagnosing apparatus of claim 1, wherein the voice diagnosing unit comprises:

a comparing unit configured to compare the voice feature extracted by the voice analyzing unit with the abnormal state reference;

a monitoring unit configured to detect a change over time in a voice state of the user; and

a diagnosis processing unit configured to diagnose a state of the user'"'"'s health according to a result of the comparison by the comparing unit, and the change detected by the monitoring unit.

7. The health diagnosing apparatus of claim 6, further comprising a storage unit configured to store an output of the diagnosing processing unit and diagnosis time information.

8. The health diagnosing apparatus of claim 1, wherein the diagnosis outputting unit comprises:

a digital signal processor configured to convert information regarding the health state and a health state change diagnosed by the voice diagnosing unit into one or more audio or video signals;

a display unit configured to output a video signal converted by the digital signal processor; and

a speaker configured to output an audio signal converted by the digital signal processor.

9. A method of diagnosing a user'"'"'s health, the method comprising:

detecting and monitoring a voice of the user;

extracting a voice feature from the detected voice;

diagnosing the user'"'"'s voice by comparing the extracted voice feature with a reference;

outputting a predetermined warning indication based on a result of the comparing.

10. The method of claim 9, wherein the detecting the voice comprises:

converting an input voice into a digital voice signal; and

detecting the voice of the user from the digital voice signal.

11. The method of claim 9, wherein the extracting the voice feature comprises:

determining the health state type to be diagnosed;

selecting a voice period for a diagnosis according to the health state type;

selecting a voice feature corresponding to the health state type; and

extracting the selected voice feature from the selected voice period.

12. The method of claim 9, wherein the diagnosing the health state further comprises:

analyzing a change over time in the health state; and

outputting an advising message according to the change over time in the health state.

13. The method of claim 9, wherein the diagnosing the health state and the monitoring the change in the health state comprise:

comparing the extracted voice feature with the abnormal state reference;

detecting a change over time in a voice state; and

diagnosing the health state of the user according to a result of the comparison, and the change over time in the voice state.

14. The method of claim 13, further comprising storing and updating a result of the diagnosing and diagnosis time information in a storage unit.

15. The method of claim 13, further comprising determining references with respect to an abnormal voice and a normal voice.

16. The method of claim 15, wherein the determining the references comprises:

forming an abnormal voice database and a normal voice database;

extracting an abnormal voice feature and a normal voice feature from the abnormal voice database and the normal voice database, respectively;

performing comparison training with respect to the extracted abnormal voice feature and the extracted normal voice feature; and

determining the abnormal state reference according to the comparison training.

17. The method of claim 9, wherein the outputting comprises:

converting information regarding the health state and the health state change into one or more audio or video signals; and

outputting the one or more audio or video signals.

18. A computer-readable recording medium having recorded thereon a program for executing a method of diagnosing a user'"'"'s health, the method comprising:

detecting and monitoring a voice of the user;

extracting a voice feature from the detected voice;

diagnosing the user'"'"'s voice by comparing the extracted voice feature with a reference;

outputting a predetermined warning indication based on a result of the comparing.
