Built for training, cleared for commercial use
Spontaneous, not scripted
Real two-person conversations with natural disfluencies, turn-taking, and code-switching. These are the acoustics your ASR model meets in production, not a reading booth.
Consent chain, documented
Every speaker signed an explicit commercial-use consent. We hand you the documentation, so GDPR and EU AI Act reviews don’t stall your procurement.
Transcripts & metadata included
Time-aligned, QA’d transcripts plus speaker age, gender, region, and recording-device metadata, ready for filtering, balancing, and evaluation splits.
Samples before you commit
Request free samples from any dataset and run your own audit: audio quality, transcript accuracy, speaker diversity. Judge the data, not the deck.
Transparent per-hour pricing
$60-$95 per hour depending on language, published on every dataset page. Volume and multi-language discounts on request.
