Multi-party conversation analyzer and logger
View Patent ↗In one aspect, the present invention facilitates the investigation of networks of criminals, by gathering associations between phone numbers, the names of persons reached at those phone numbers, and voice print data. In another aspect the invention automatically detects phone calls from a prison where the voiceprint of the person called matches the voiceprint of a past inmate. In another aspect the invention detects identity scams in prisons, by monitoring for known voice characteristics of likely imposters on phone calls made by prisoners. In another aspect, the invention automatically does speech-to-text conversion of phone numbers spoken within a predetermined time of detecting data indicative of a three-way call event while monitoring a phone call from a prison inmate. In another aspect, the invention automatically thwarts attempts of prison inmates to use re-dialing services. In another aspect, the invention automatically tags audio data retrieved from a database, by steganographically encoding into the audio data the identity of the official retrieving the audio data.
1. A system for identifying an unauthorized participant to a phone call between a calling party and called party, the system comprising:
a processor;
a memory coupled to the processor, the memory storing computer-readable instructions that, upon execution by the processor, cause the system to:
create a first digital data stream from audio of the calling party side of the phone call;
create a second digital data stream from audio of the called party side of the phone call;
output the first digital data stream to a first loudspeaker primarily coupled to one ear of a user; and
output the second digital data stream to a second loudspeaker primarily coupled to the other ear of said user.
2. The system of claim 1 , wherein the phone call is pre-recorded.
3. The system of claim 1 , wherein one of calling party or the called party is within a correction institution.
4. The system of claim 1 , the memory storing additional computer-readable instructions that, upon execution by the processor, cause the system to:
detect a new voice participating in the phone call.
5. The system of claim 4 , wherein the user determines whether the new voice is on the calling party side or the called party side of the phone call.
6. The system of claim 1 , wherein the first loudspeaker and the second loudspeaker are comprised within a set of headphones or earbuds.
7. A method for identifying unauthorized participants in a phone call between a calling party and called party, the method comprising:
creating a first digital data stream from audio of the calling party side of the phone call;
creating a second digital data stream from audio of the called party side of the phone call;
outputting the first digital data stream to a first loudspeaker primarily coupled to one ear of a user; and
outputting the second digital data stream to a second loudspeaker primarily coupled to the other ear of said user.
8. The method of claim 7 , wherein the phone call is pre-recorded.
9. The method of claim 7 , wherein one of calling party or the called party is within a correction institution.
10. The method of claim 7 , further comprising:
detecting a new voice participating in the phone call.
11. The method of claim 10 , wherein the user determines whether the new voice is on the calling party side or the called party side of the phone call.
12. The method of claim 7 , wherein the first loudspeaker and the second loudspeaker are comprised within a set of headphones or earbuds.
13. A non-transitory tangible computer-readable storage medium having program instructions stored thereon that, upon execution by a communications system, cause the communications system to:
create a first digital data stream from audio of the calling party side of the phone call;
create a second digital data stream from audio of the called party side of the phone call;
output the first digital data stream to a first loudspeaker primarily coupled to one ear of a user; and
output the second digital data stream to a second loudspeaker primarily coupled to the other ear of said user.
14. The storage medium of claim 13 , wherein the phone call is pre-recorded.
15. The storage medium of claim 13 , wherein one of calling party or the called party is within a correction institution.
16. The storage medium of claim 13 , wherein the program instructions further cause the communications system to:
detect a new voice participating in the phone call.
17. The storage medium of claim 16 , wherein the user determines whether the new voice is on the calling party side or the called party side of the phone call.
18. The storage medium of claim 1 , wherein the first loudspeaker and the second loudspeaker are comprised within a set of headphones or earbuds.
