How to use the Tag Vowels recognizer from within ELAN

The Tag Vowels recognizer written at the Max Planck Institute for Psycholinguistics uses the Praat analysis of f0 (pitch) and volume of a given audio recording to spot timespans which are likely to correspond to spoken vowels. This can be interesting for measuring speech rate (counting syllables per time) or for gathering information about prosody: The raw Praat data is available as additional output. The web service version has Praat installed on the same server, but it is also possible to install the recognizer on the computer where ELAN is running. In that case, Praat has to be installed first. The Praat software is available for Linux and Windows from UvA, it is free open source software. The recognizer itself is available, also as free open source software, from the MPI for Psycholinguistics. This recognizer also demonstrates the various types of possible input, output and setting objects within the AVATecH and AUVIS frameworks.

AVATecH and AUVIS compatible recognizers have the following categories of settings, input and output elements:

Your default ELAN configuration invokes a CLAM REST web service wrapper on catalog.clarin.eu to have your files analyzed. In other words, your media files and, if applicable, input tiers will be uploaded for processing and ELAN will process the downloaded (tier or other) results as if you had done the processing locally. For use in situations where a web service can not be used (too large files or no internet available) you can also request a copy of the recognizer for local installation on Linux or Windows, protected by USB dongle.

For this and for general support with the use of this recognizer, please contact auvis@mpi.nl or use the ELAN and AUVIS forums on the website of The Language Archive.

CLAM, ELAN and the client-side recognizer proxy are free open source software under the GNU General Public License - however, some of the recognizers can be propietary closed source software. Licenses for academic use are available on request. Use of the web services is free at the moment, but may be limited to the academic community if it becomes necessary.
