CHAT Main Line
The CHAT main line codes the basic transcription of what a speaker said. The main line includes both pronounced forms and markers. In CHAT the main line starts with an asterisk followed by the speaker ID, a colon and a tab; the remainder of the line is the orthographic transcription. More information about the CHAT main line can be found at https://talkbank.org/manuals/CHAT.html#_Toc486414395.
E.g.,
*CHI: hello world!
In Phon, the main line is mapped to the Orthography tier. Each main line in a CHAT document cooresponds to a single record in a Phon session. Phon supports many of the same coding standards as CHAT. See https://talkbank.org/manuals/CHAT.html#_Toc486414395 for complete documentation.
