This is the introduction to the wiki from the front page.
TVT is a learning tool for students of the Thai language. There are nearly endless Thai videos on sites like YouTube and KosanaThai. On TVT, users work together to transcribe the text of these videos. This process will help you to improve your understanding of Thai as actually used by native speakers, and makes it simple to copy-and-paste unfamiliar words into websites like thai2english.com, thai-language.com, or thai.sealang.net.
This is a great resource for Thai language students.
