SA can also combine phonetic, phonemic, orthographic, tone and gloss transcriptions in an interlinear format. Features to enhance language learning include slowed playback, repeat loops and overlays to assist with perception and mimicry of sounds. With SA, ethnomusicologists can perform analysis of music recordings. Version 3.0 is the first significant release of SA since version 2.7 (June 2005).

SIL researches and develops computer software solutions needed to facilitate the study of languages and the publication of literature in a variety of writing systems. SIL has developed more than 60 pieces of software to support the work of its fieldworkers. Most are available to the public for free download.

SIL’s field linguists work in partnership with minority language speakers, local and national government agencies, nongovernmental organizations and universities to collect, analyze, organize and publish language and culture data. SIL workers serve as technical advisors, teachers, consultants and facilitators. As an international advocate for minority language speakers, SIL is dedicated to supporting ethnic minority peoples worldwide in their efforts to preserve their languages and cultural identities into the 21st century.
