Require continuous labeling queues for live RLHF cycles?
We set up secure daily delivery micro-queues, scaling human-vetted feedback alongside model deployment updates.
Our Success Stories
Scaling Multilingual Audio Data Collection for AI Model Training
We helped a leading technology and mobility company build large-scale multilingual audio datasets across 26 locales for speech recognition and AI model training, capturing natural conversational speech rather than scripted reads.
The Challenge
Recruiting 400+ contributors across 26 locales within two months, including hard-to-source accents, and producing 650+ hours of natural conversational audio at a pace no standard recording tool could support.
The Solution
Built custom software for simultaneous multi-person conversational recording, tapped our global office network to source contributors across all 26 regions, and ran an automated workflow for daily QA and delivery tracking.
