Annotating files
Annotating the picture book files in ELAN is similar to audio files in ELAN. Listen to the recording.
Notes linked here: PBS Annotation Set
FA1: Female Adult 1 - Most commonly used. If there is a second parent, one can add in MA1 for Male Adult 1, FA2 and so on, PA2 - here transcribing the text that is head. It mostly comes from the book so having the book transcript side by side helps.
CHI: For Target Child Utterances, only indicated sound by xxx. (not attempting to interpret, just the start and stop time of the vocalizations). If there is a second child adding in as
CHI2.
xds@FA1 - To indicate who the parent is talking to (T - target child, A- Another Adult)
txt@FA1- To indicate if the parent is talking from the book or off-book (B - Book, C - Conversation) . This could be extended.
Comments -Any comments
Coding Notes:
Onomatopoeia: When there is onomatopoeia in the transcription, follow with @o.
If the word "apple" is said in reference to shang or similar, include the comment "Semantic neighbor."
Additional conventions:
[!= whispers].

Note: Most of the utterance types in these files will be "B" for "Book Reading", but pay extra attention to different utterance types - it's easy to forget and just type "B" for everything.
