Note from the founder
During the pandemic I tried to turn the books I loved into audio I could actually listen to. The technology was supposed to be ready. It wasn't. Voices mispronounced names, flattened the emotion, and fell apart the moment a sentence got complicated. In English it was frustrating. In my own language, and in most of the world's languages, it was far worse.
The surprising part is that the models were never the problem. Today's voice models are extraordinary. The gap is in everything around them: picking the right one, guiding it, and checking that what comes out is genuinely good enough to publish. That layer barely existed, and the moment to build it is now.
So we did. We started Podonos to measure voice quality at scale, and Onepin is what we built on top of it: the layer that turns great models into voice you can ship, in any language.
Production-quality voice for everyone with something to say, in the language they say it in.
