AUDIO MINING: THE NEXT BIG THING?
12 March 2002
One of the benefits that emerging audio mining technologies provide is faster and more efficient monitoring of potential threats in an increasingly security-conscious world, according to Cutter Consortium Senior Consultant Curt Hall.
States Hall, "Audio mining technology makes it possible to retrieve specific information from hours of recorded or live video footage, radio and television broadcasts, telephone conversations, call center dialogs, help desk recordings, and other formats.
"In effect, audio mining engines create a high-level structured summarization of the spoken language that can be searched and browsed using different criteria -- such as the names of people, places, organizations, and topics mentioned in the transcript as well as the identities and locations of the speakers in the recording."
Audio mining technology combines speech recognition, language processing, and intelligent indexing and search algorithms to transcribe the content of video or audio broadcasts into computerized text information. Promising application areas for audio mining technology, says Hall, include the following:
Technical support centers and help
desks. A technical support manager
responsible for providing feedback to a product
development team can search a database of recorded
technical support calls to determine the issues end
users are contending with.
Call centers. A stockbroker or
call center operator can gain access to specific
recorded conversations to verify transaction
information. Marketing executives can access
customer requests and feedback from a company
database to fine-tune marketing campaigns.
Broadcast media. A news editor at
a TV or radio station can search archives of
recorded broadcasts to retrieve information
relevant to breaking news almost immediately. The
technology can also be used to index live
Corporate communications and public
relations departments. Communications and
PR managers can index and search both live video
feeds and archived broadcasts to track how their
company or a competitor is being covered in the
Conference managers. A conference
management organization can use audio mining to
create an index of key topics to help in preparing
tapes of sessions. Such an index would allow
material on CD-ROM to be directly accessible.
Intelligence gathering, law enforcement,
and security operations. Security
personnel can obtain critical information from
hours of recorded phone calls or radio
transmissions much more rapidly than before. The
technology also allows the indexing and searching
of live broadcasts in order to monitor breaking
