CHAT Transcription Format
- Note
- BOF, Offset 0, Max Offset 256, using 4 mandatory elements, although there are some additional non-mandatory elements that may also appear near BOF: ‘@UTF8’ {0-256} ‘@Begin’ {0-64} ‘@Languages:’ {0-256} ‘@Participants:’ – see https://talkbank.org/manuals/CHAT.pdf. As such these relative offsets between elements may need to be adjusted as more examples of this format are encountered.
