1.5.11. Audio And Video Recognizers

The Recognizers tab provides a user interface to recognizer components that have been installed as extensions. These recognizer components generally apply pattern recognition algorithms to automatically detect events of interest (pauses, speaker turns, utterances, gesture phases etc.) in an audio or a video file. Each recognizer has it's own icon representing the kind of recognizer.

There is one audio recognizer included in the ELAN distribution, the Silence Recognizer (seeSection 2.4.3). The screenshot below displays all AVATecH available recognizers installed.

The AVATecH project page (https://tla.mpi.nl/projects_info/avatech/) can be consulted for more information (including an interface specification) and how to install more recognizers. More information on how to interact with the recognizers will be included in this manual at a later stage.
