General conversation speech
Spontaneous telephonic conversation from native speakers, recruited against region quotas.
Overview
Paired conversational speech recorded over mobile and landline networks. Participants were given a topic to discuss and left to talk. Recruitment was held to age, gender and district quotas so the set does not collapse into urban young men, which is what an open crowd call produces.
