Custom conversational collection
Full-duplex conversational speech data for turn-taking and interruption models
Collect real two-speaker interaction with separate channels, natural overlap, interruptions, backchannels, and timing metadata for speech-to-speech systems and low-latency voice agents.
Example availability: Tell us your target language and dialogue setup. The team will check whether a relevant separate-channel conversation example can be shared free of charge, then confirm the available options and timing.

Conversation is more than alternating clean turns
Human speakers acknowledge, interrupt, hesitate, restart, and speak at the same time. A model trained only on isolated utterances or neatly alternating dialogue does not learn when to listen, yield, continue, or recover.
Separate synchronized channels preserve those events without forcing diarization to guess who spoke. The annotation scope can stay lightweight or extend into precise turn-taking labels depending on the model job.
Agree the interaction and acceptance rules first
Define speakers per session, language and accent quotas, channel synchronization, and which overlaps, backchannels and interruptions the annotation must distinguish. Use a first batch to check the channel map, transcripts and turn-timing fields against your pipeline.
Two-speaker conversation is the starting scope. Meeting-style projects add participant counts, microphone geometry and per-speaker reference requirements for feasibility review. The proposal confirms which recording and annotation components are included.
This offer is not the right fit when
- You only need isolated command recordings.
- Synthetic dialogue is acceptable for every evaluation condition.
- You need an off-the-shelf fixed corpus with no collection lead time.
