Twi–English code-switching multimodal dataset (ELAN annotations + derived features)

ELAN annotations, derived tables and analysis scripts for a study of gesture and prosody in naturalistic Twi–English code-switching (11 clips, 65.1 min, 4 speakers, 837 annotated gestures, 1,089 switch points). Version 1.1.0 corrects the gesture-density (RQ3) and gesture–F0 alignment (RQ2) analyses: onset-based, speech-only density with a window-shift permutation baseline, and a matched permutation test for alignment. Annotations and the other derived tables are unchanged from v1.0.0. Results from v1.0.0 (density ratio 2.30×; 51.6% of onsets within 50 ms of an F0 peak) are superseded. Videos are not included.
