Why teams buy from us

Built for training, cleared for commercial use

01

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.

02

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.

03

Transcripts & metadata included

Time-aligned, QA’d transcripts plus speaker age, gender, region, and recording-device metadata, ready for filtering, balancing, and evaluation splits.

04

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.

05

Transparent per-hour pricing

$60-$95 per hour depending on language, published on our catalogue dataset pages. Volume and multi-language discounts on request.
