Two sources feed this collection. Field capture on lavalier — market negotiation, workshop instruction, household conversation — and cleared archive from radio talk and call-in programming across anglophone and francophone stations. Natural multi-speaker conversation with genuine overlap and interruption is the hardest single requirement in speech data; it is also what an entire broadcast tradition in this region consists of. Delivered with speaker labels, diarisation and timestamped transcripts.
Market price negotiation, three speakers, heavy overlap, Yoruba–Pidgin code-switching
Overlap ratio 0.19 with 47 code-switch events. Three speakers, two of whom interrupt each other repeatedly. This is the acoustic and turn-taking profile that scripted collection cannot reproduce.
