How does a child break into a conversation that is already underway? I work on detecting the moment a child enters multiparty talk in naturalistic home recordings, using linguistic alignment as the diagnostic: when speakers are engaged in the same interaction, their language converges, so a drop in alignment can mark the boundary where a child joins or leaves. The measurement builds on ALIGN 2.0, a toolkit for quantifying alignment across conversational speech, applied here to daylong caregiver-child audio.
Much of my work is the pipeline that makes this analysis possible: carrying ELAN-annotated recordings into the format the tools expect, preserving the messy realities of child speech such as sung and wordless vocalisations, and running alignment measures over the result. I will present this research in a talk at the ICIS Founding Generation Symposium in September 2026, on identifying multiparty conversation in naturalistic environments through both temporal and alignment-based measures.
