Telephony system and method with enhanced call monitoring, recording and retrieval
First Claim
1. A method practiced in data processing apparatus for monitoring and recording telephone calls, the method comprising in said data processing apparatus:
- generating high quality digital electronic voice signals representative of voice signals present on a telephone call,monitoring said high quality electronic digital voice signals for the presence of particular predetermined words or phrases, said predetermined words or phrases from a call participant-specific word profile, said monitoring including flagging selected ones of said digital voice signals thereby to generate flagged electronic digital voice signals,temporarily storing said high quality electronic digital voice signals, including said flagged electronic digital voice signals, in a first state memory apparatus, wherein said signals are only stored for a specified short term storage period,at the expiration of the specified short term storage period, compressing said electronic digital voice signals to form compressed electronic voice signals and storing said electronic compressed voice signals for long-term storage in a second memory apparatus,indexing said stored electronic compressed voice signals,selectively retrieving said stored electronic compressed voice signals,monitoring said selectively retrieved stored electronic compressed voice signals at one or more monitoring stations, andmonitoring on a priority basis selected ones of said flagged electronic digital voice signals at said one or more monitoring stations.

7. A method for recording telephone calls between a first telephone in an institution in which telephone users are subject to restricted telephone calling privileges and a second telephone, the method comprising:
-
in a first converter, receiving first telephone call signals from said first telephone, said first converter being adapted for converting such first telephone call signals to signals of a form suitable for application to a communications network, in a second converter, receiving second telephone call signals from said second telephone by way of a network, said second converter being adapted for converting said second telephone call signals to signals of a form suitable for use by said first telephone, in a first digital recorder, selectively recording first content signals representing information content of said first and second telephone call signals, in a speech recognizer, identifying the presence and place of occurrence in said first content signals of respective occurrences of one or more of a set of predefined words or phrases, and wherein said selectively recording said first content signals includes recording information relating to said place of occurrence in said first content signals of respective occurrences of said set of predefined words or phrases, and said selectively recording said first content signals is performed subject to a first quality metric, wherein selection of said first quality metric is based on currently existing telephone call conditions, and based on the occurrence of one or more of said set of predefined words or phrases in said first content signal and upon profile information, sending said first content signals from said first digital recorder via an electronic communication for playback at one or more monitoring stations wherein said first content signals are selectively communicated to notify a particular person, office, or vehicle identified by said profile information. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23)

24. A method practiced in data processing apparatus for monitoring and recording telephone calls, the method comprising in said data processing apparatus:
-
generating high quality digital electronic voice signals representative of voice signals present on a telephone call, temporarily storing said high quality electronic digital voice signals, including said flagged electronic digital voice signals, in a first state memory apparatus, wherein said signals are only stored for a specified short term storage period, wherein the short term storage period is longer for telephone calls for which the presence of particular predetermined words or phrases have been identified than for telephone calls for which the presence of the particular words or phrases have not been identified, and at the expiration of the specified short term storage period, compressing said electronic digital voice signals to form compressed electronic voice signals and storing said electronic compressed voice signals for long-term storage in a second memory apparatus. - View Dependent Claims (25)
