Abstract

The present invention relates to a method and system for measuring and quantifying user's stress levels through voice signal analysis. The method comprising collecting user's voice sample through a phone call or one or more voice receivers; breaking the user's voice sample in myriad of parameters of voice attributes; assigning scores/weight-ages/numeric values to each voice attribute for the collected user's voice sample by computer - implemented software; calculating the assigned stress scores/weight-ages/numeric values using an algebraic equation involving all the voice attributes; combining all individual voice attributes scores to total stress score/weight-age/numeric value; communicating the total stress score/weight-age/numeric value to a user device; and assigning and sending an avatar representation explaining the level of total score/weight-age/numeric value attained by the user. The scores/weight-ages/numeric values assigned to each voice attribute are based on correlation studies with cortisol levels in the body.

Claims

AMENDED CLAIMS received by the International Bureau on 07 October 2015 (07.10.2015) WE CLAIM:
1. A method for measuring and quantifying user's stress levels through voice signal analysis comprising:
Collecting user's voice sample through a phone call or one or more voice receivers;
Breaking the user's voice sample in myriad of parameters of voice attributes;
Assigning scores or weight-ages or numeric values to each voice attribute for the collected user's voice sample by computer - implemented software;
Calculating the assigned stress scores or weight-ages or numeric values using an algebraic equation involving all the voice attributes;
Combining all individual voice attributes scores to total stress score or weight-age or numeric value;
Communicating the total stress score or weight-age or numeric value to a user device; and
Assigning and sending an avatar representation explaining the level of total score or weight-age or numeric value attained by the user,
wherein the scores or weight-ages or numeric values assigned to each voice attribute are based on correlation studies with Cortisol,
wherein the voice attributes includes but not limited to pitch variance, energy variance, spectral slope, fO mean, jitter and loudness, and
wherein the method provides non-biased, consistent scoring of user's stress for encouraging preventive healthcare system.
2. The method as claimed in claim 1, wherein validation is done for the initial set of users by correlating with Cortisol hormone released from the users during stress.
3. The method as claimed in claim 1, wherein the avatar representation is classified into zones in accordance to the level of total score or weight-age or numeric value attained by the user.
4. The method as claimed in claim 3, wherein the zones includes but not limited to calm, good stress, medium stress and high stress.
5. A system for measuring and quantifying user's stress levels through voice signal analysis comprising:
One or more voice receivers;
Central processor;
Memory in communication with the central processor; and
User device,
wherein the voice receiver is a microphone, which collects user's voice sample, wherein the user's voice sample is broken in myriad of parameters of voice attributes, wherein the central processor that includes software with an algorithm assigns scores or weight-ages or numeric values to each voice attribute for the collected user's voice sample,
wherein the scores or weight-ages or numeric values assigned to each voice attribute are based on correlation studies with Cortisol,
wherein the assigned scores or weight-ages or numeric values are calculated using an algebraic equation involving all the voice attributes and combined to give total score or weight-age or numeric value,
wherein the total stress score or weight-age or numeric value is sent to the user device by the memory in communication with the central processor,
wherein the voice attributes includes but not limited to pitch variance, energy variance, spectral slope, fO mean, jitter and loudness, and
wherein the system provides non-biased, consistent scoring of user's stress for encouraging preventive healthcare system.
6. The system as claimed in claim 5, wherein the user device is a mobile phone.
7. The system as claimed in claim 6, wherein validation is done for the initial set of users by correlating with Cortisol hormone released from the users during stress.
