Service for providing speaker voice metrics

1. A method of providing biometric information over a telephone call established between a speaker and a subscriber comprising:

subscribing a voice analysis service by the subscriber;

receiving a voice stream from the speaker, said voice stream including a plurality of voice signals of the speaker;

invoking the voice analysis service by the subscriber;

providing the voice signals to the voice analysis service;

determining biometric information from the voice signals of the speaker by the voice analysis service;

identifying inaudible portions in the voice stream using a psychoacoustic model;

modifying said voice stream by encoding the determined biometric information and replacing the identified inaudible portions of the voice stream with said encoded information; and

transmitting the modified voice stream to the subscriber over the established telephone call.

2. The method of claim 1 , said determining step comprising:

extracting at least one attribute from the voice signals;

comparing the at least one attribute with voice metrics; and

generating the biometric information based upon said comparing step.

3. The method of claim 1 , wherein at least one other speaker is connected to the call, and wherein the method further comprises:

prior to said receiving step, selecting one among the voice signals of the speaker and the voice signals of the other speaker to be analyzed; and

performing the steps of receiving, determining, generating, identifying, encoding, and transmitting only for said selected speaker.

4. The method of claim 1 , wherein the biometric information specifies at least one of an indication of voice level, stress level, voice inflection, and an emotional state.

5. The method of claim 1 , wherein the subscriber receives the voice signals and the associated biometric information, both of the speaker, substantially concurrently over the call.

6. The method of claim 1 , further comprising:

extracting the embedded biometric information from the transmitted voice stream;

decoding the extracted biometric information; and

presenting the information to the subscriber.
