Catalog

The languages we serve, produced continuously.

Languages nearly absent from the web, and therefore from your training data. We produce them in studio, with native speakers under contract.

Annotation

Every hour is annotated across 14 layers. One corpus, many voice systems.

ASR, TTS, speech translation, voice agents, voice servers: the same corpus powers the training, fine-tuning and evaluation of your models and machines.
