WHAT IS IT?
Software that creates a searchable index of speech content embedded in digitized audio and video files. It date- and time-stamps each word or phoneme in order to rapidly identify and access target segments.
WHAT'S THE BENEFIT?
Allows quick searches for and rapid access to audio content.
BEST APPLICATIONS
Indexing and data mining of broadcast audio content, speeches, e-learning content and audio reports, as well as real-time alerts of live audio feeds based on keywords.
CAVEATS
Accuracy is still improving. Indexed output text, while acceptable for searching, doesn't produce a usable transcript. Depending on the application, vocabulary sets may require frequent updating to maintain accuracy levels.
