In this article we present the IATH ELAN Text-Sync Tool (ETST; see http://community.village.virginia.edu/etst), a series of scripts and workflow for playing ELAN files and associated audiovisual media in a web browser either on- or off-line. ELAN has become an indispensable part of documentary linguists' toolkit, but it is less than ideal for mobilizing the transcribed media it allows linguists to create when they have reason to display these materials in non-research settings where linguists are not the primary audience. In conjunction with display of a video or audio file, ETST plays tiers of transcript for overlapping speech, along with optional glosses, and distinguishes speakers with participant codes. Using ETST requires no programming knowledge, but with some such knowledge the tool can be readily customized to suit users' needs. To that extent, ETST is a simple browser-based transcript player that can be used either as is, "out of the box," or as a basis for further development. We hope that ETST will be a helpful addition to documentary linguists' repertoire of digital tools, making it easier for them to share materials with all those who have a stake in their research.
