Any canonically spelled series of words or proper nouns, with standard sentence-final punctuation, commas, and the following CHAT-specific markup:

Markup Meaning Example
# Disfluency bonjour@f
@f Foreign word bonjour@f
@l Letter a@l

+... Unfinished sentence I just want to +... (child trailed off)

3.5.4. Vertical Dependencies

None

3.5.5. Horizontal Dependencies

CHAT is dependent upon the Utts Column for its base content. To convert the transcribed entry in the Utts Column, the following changes are made:

  • All disfluencies and repetitions are removed
  • All filler words (such as “oh”, “um”, and “uh”) are preceded by an &
  • A space is placed between the final word and the punctuation mark
  • A few symbols from the Utts column are reformatted in the CHAT column to make the utterances compliant with the CHAT formatting rules according to the following table:
Utts Symbol CHAT Symbol Meaning
### &xxx Unintelligible speech
-- (mid-sentence) # Disfluency or repetition marker
-- (sentence-final) +... Speaker did not finish sentence
