SIL (Larry Hayashi, Gary Simons, Terry Gibbs)
The Summer Institute of Linguistics (SIL) has enormous experience in providing tools and data formats for use in primary linguistic description. LinguaLinks is "an electronic productivity support system for language workers," based on the CELLAR object-oriented "Computing Environment for Linguistic, Literary and Anthropological Research.", including linguistics tools. Other SIL software tools are Speech Analyser and Speech Manager, Windows programs for labelling speech files and for searching a database of labelled speech files; Shoebox, for interlinear text annotation and its predecessor, IT. SIL also has an SGML based annotation format named PTEXT ("parsed text") described in this paper.
