Abstract

A system is configured to receive voice emotion information, related to an audio recording, indicating that a vocal utterance of a speaker is spoken with negative or positive emotion. The system is configured to associate the voice emotion information with attribute information related to the audio recording, and aggregate the associated voice emotion and attribute information with other associated voice emotion and attribute information to form aggregated information. The system is configured to generate a report based on the aggregated information and one or more report parameters, and provide the report.

join the voice emotion information with the attribute information by use of a unique identifier related to at least one of;

the audio recording;

the speaker;

a location associated with the speaker;

a product associated with the speaker;

or

a subject associated with the vocal utterance.

6. The system of claim 1, where the one or more server devices are further to:

receive the one or more report parameters from a user.

7. The system of claim 1, where the one or more server devices, when generating the report based on the aggregated information and the one or more report parameters, are further to:

generate a report including a count of words or phrases, within the aggregated information, associated with negative or positive emotion, relating to at least one of;

the speaker;

a location associated with the speaker;

a product associated with the speaker;

or

a subject associated with vocal utterance.

8. A computer-readable medium storing instructions, the instructions comprising:

a plurality of instructions that, when executed by one or more processors, cause the one or more processors to;

receive voice emotion information related to an audio recording,

the audio recording containing a vocal utterance of a speaker, and

the voice emotion information indicating that the vocal utterance relates to a particular emotion;

receive attribute information related to the audio recording;

associate the voice emotion information with the attribute information;

aggregate the associated voice emotion and attribute information with other associated voice emotion and attribute information to form aggregated information;

generate a report based on the aggregated information and one or more report parameters; and

provide the report.

9. The computer-readable medium of claim 8, where the plurality of instructions further cause the one or more processors to:

analyze a vocal prosody characteristic of the vocal utterance; and

detect that a word or a phrase, within the vocal utterance, is spoken with negative or positive emotion based on the vocal prosody characteristic,

the voice emotion information including information regarding the detected word or phrase.

10. The computer-readable medium of claim 8,

where the speaker is a first speaker, and the vocal utterance is a first vocal utterance,

where the plurality of instructions further cause the one or more processors to:

detect that the audio recording includes the first vocal utterance of the first speaker and a second vocal utterance of a second speaker;

associate a first word or phrase, within the first vocal utterance, with the first speaker; and

associate a second word or phrase, within the second vocal utterance, with the second speaker, the voice emotion information including information regarding the first word or phrase or the second word or phrase.

11. The computer-readable medium of claim 8, where the attribute information includes information identifying at least one of:
