Trova is a search engine for annotation content archived at The Language Archive. Searchable formats include ELAN EAF, Childes CHAT, Toolbox, PDF, SubRip, Praat TextGrid and others. Results can be viewed as concordance or frequency view and exported as CSV. Tool-tips show additional hit information and hits can be displayed in Annex. You can also jump to the corresponding archive tree location for each hit.

To use Trova, select ‘annotation content search’ in the node context menu (right clicking on a node in the tree) when browsing the archive tree, or do a metadata search and proceed from the search results to a content search in the found sessions and resources. You can also select multiple nodes (corpora) in the archive tree, then right-click to get a context menu to search in multiple corpora at the same time.
