MAM Search Even In Metadata Absence
The key to unlocking an archive's potential is phoneme-based dialogue search - this offers fast accurate results...

By K J Kandell, Sr Director, Nexidia
Media & Entertainment Division

M

ost media organisations have
vast stores of content resulting
from years of production - from
news broadcasts to television
programmes to recorded speeches
or concerts to corporate videos.
Thanks to the advent of digital
data and file-based workflows,
media organisations of all shapes
and sizes can digitise that content
and repurpose it to reach new
audiences, serve the second and
third screens, or create completely
new programming. Most importantly
for many organisations, repurposing
content can result in a new way to
monetise the video assets and
archives that are sitting on their hard
drives. In addition, with increasing
government requirements related to
issues such as loudness and closed-

captions, it is simply good practice
to be able to locate assets quickly
in order to prove compliance and
avoid costly fines.
However, when it comes to media
assets, if you can't find them, then
you can't repurpose them, so they
might as well not exist.
That's why content owners need
simple, accurate, cost-effective
tools for locating specific pieces of
media. Media Asset Management
(MAM) systems hold basic, filebased metadata such as date,
timecode, and duration, but often
there is little descriptive metadata
about the content.
Most media operations just don't
have the resources to do any regular
or thorough logging or transcription
- a laborious process that requires

Dialogue Search - quickly search and preview results

someone to watch every bit of
the video in a logging application
and make descriptive notes about
the content - and even if they did,
manual logging and transcription
yield limited detail and significantly
increase the lag time between when
the assets are ingested and when
they are available for use.
Even the most advanced MAM
systems are unable to return
meaningful results if there is not
enough descriptive metadata
associated with the assets. Image
recognition reveals who's pictured,
but not what they're saying.
Speech-to-text has had insufficient
performance and accuracy to be
useful even on the clearest speech.

Valuable Assets

Dialogue, on the other hand, is the
ultimate descriptive metadata and
applies to almost all programme
types. One product, Nexidia
Dialogue Search, relies on
dialogue to locate any spoken
word or phrase across massive
media libraries in seconds, thereby
uncovering valuable assets that
basic, file-based metadata could
never expose. It works by analysing
phonemes instead of words,
making it far more accurate than
speech-to-text.
When an asset or library is selected
for indexing, software analyses
the audio tracks and creates a
searchable, phonetic index of the
dialogue. That process - which
takes place hundreds of times faster
than real-time on a multicore server
- results in the ability to search based
not on the information that has been
typed into the metadata fields during
the logging process, but on what is
actually spoken on the audio tracks.
Once the index is created,
descriptive metadata is no longer
required to search for an asset
(though the system can still leverage
basic information such as creation
date and source), and searches
become almost instantaneous.

For example, Dialogue Search
can search through more than
250,000 hours of media in just
over five seconds. The product
has broad language support (ten
different languages and dialects and
counting), and is not thrown off by
slang or individual accents.
Like performing a Google or
YouTube search, users simply
type any combination of words or
phrases into the interface, and the
application will quickly produce a
list of video results of every instance
where that word or phrase was
spoken. From there, each result
can be selected and shown on
a resident player. The product
integrates directly with MAM
systems and editing applications,
so when users find the results they
need, they can quickly export the
search terms and timecodes back to
those systems, making for an even
more efficient workflow.
Major networks, government
organisations, sports leagues,
churches, research organisations,
and many more media-oriented
o p e r a t i o n s re c o g n i s e t h a t
finding video assets easily has
been a crucial factor in fulfilling
programming requirements,
maintaining compliance, serving
their constituents, and realising
revenue streams.
Considering the time it would
take to tag assets properly in order
to make them searchable, the
value of a phonetic-based solution
becomes evident - and media
organisations large and small have
realised it. Automated, phoneticbased dialogue search is accurate,
lightning-fast, affordable, and
can integrate with existing MAM
systems and editing applications.
It also applies broadly to any
industry that creates, owns, or
distributes content. Crucially, it
yields results even in the absence of
descriptive metadata, which allows
media organisations to reap the full
benefit of their archives.
