How to use COALA

COALA is a tool to convert simple text tables into CLARIN Metadata-Files (CMDI) for multimodal corpora. If you want to learn more about CMDI in general we refer to this page. As many other CLARIN tools, COALA is a free web service that can be found on the website of the Bavarian Archive for Speech Signals (BAS)

To get your CMDI you just have to upload your files, give your corpus a name and a title and hit the green COALA button to convert your files. Within a few seconds you can download your zipped file which contains all the metadata for your corpus.   

If you are encountering any problems, you first might want to check the logging messages at the top to see whether something went wrong. If you have further problems or questions there is a detailed description of the web service along with templates that you can download to see example inputs. Maybe there is something wrong with your tables? In case you can't find what you are looking for there is also the possibility to get help at the Helpdesk.

Online Perception Experiments with Percy

What is it?

Percy is a device-independent tool to perform online perception experiments. Researchers can learn something about spoken language via setting up an experiment design where participants listen to audio stimuli and can give their judgment about it afterwards.

For Whom is it?

Percy is a tool that can be used by researchers who want to know something about spoken language but it is also quite interesting for the participants as they can give judgements about the stimuli and manipulate them.  

And the Details?

To define an experiment design a researcher first has to think about what stimuli, input options and questions he or she wants to present to the participant. The researcher can chose among three options for setting up the experiment design: He or she can (1) use the inbuilt editor, (2) use the default user interface or (3) contact for a more advanced experiment design. There is also the possibility to choose from a set of experiments that were already conducted.
