Call centre speech
Real support calls with agent and customer channels separated and code-switching preserved.
Overview
Support conversations captured across banking, telecom, retail and logistics queues. Channels are separated where the recording allows it, and code-switching between English and the local language is transcribed as spoken rather than normalised away.
