Thailand Telecommunications Relay Service (TTRS) — Free Video, Text and Voice Relay for Deaf and Hard-of-Hearing Thais

TTRS was founded in 2011 by the Universal Foundation for Persons with Disabilities with NSTDA's A-MED centre, with initial funding from the national broadcasting and telecoms regulator's office; the NBTC later backed it as a telecom universal-service initiative. Through the myMMX app, landlines and public video-relay kiosks, an interpreter relays between a deaf or hard-of-hearing caller (sign language, text) and a hearing party, free of charge.
Reported usage: about 45,000 calls in 2012, over 115,000 calls in 2015 and more than 370,000 cumulative uses by end-2015 (nWise). The Story Thailand reports about 40,000 subscribers, of whom just over 10,000 are regular users, against roughly 400,000 Thais registered with hearing impairment.
Limits are documented honestly: only about 40 of Thailand's ~500 sign-language interpreters work for TTRS, each handling 60–70 requests a day; demand far outpaces capacity, many potential users lack devices or connectivity, and presence in education is minimal. No independent outcome evaluation was found; the evidence is usage and reach data.
