FAQ

What is full-duplex speech data?

Audio of a conversation recorded with a separate channel for each speaker, at the source. Both people can talk at once, and a single mixed track would flatten the overlap, backchannels, and interruptions that separate channels keep. fullduplex.ai, a site oto runs, explains how full-duplex voice AI is built and measured.

Are transcripts included?

Yes. The dataset comes with per-speaker ASR transcripts.

How is the dataset licensed?

Licensing is on request. Tell us how you plan to use the data and we will follow up.

Can you record other Korean conversation?

Yes. We record and annotate to specification. Tell us the topics, scenarios, and number of speakers you need.
