FAQ
Answers to the questions teams ask before they ship voice with Onepin.
General
Onepin is the agent layer for AI voice. Bring a script; we plan it, route each line to the best model, validate every line, fix what fails, and ship publish-ready audio. TTS makes voice. Onepin makes it production-ready.
Every line is scored before it ships for accuracy (WER), naturalness, noise, and pronunciation. Flagged lines are auto-fixed or regenerated. You set the bar. We hold it.
It cleans your script before generation, expanding numbers, dates, abbreviations, and symbols into how they should be spoken (for example, “$20” becomes “twenty dollars”) so the model says the right thing. Nearly half of the TTS errors are fixed by the normalizer.
Onepin already validates every line automatically for accuracy, naturalness, noise, and pronunciation, and fixes what fails before you ship. For a human sign-off on top, human validation is coming soon as a premium add-on.
Models & languages
Yes. Bring your own API key for ElevenLabs and many other providers, run it through Onepin routing and validation, and get noticeably cleaner, more consistent results from the same model.
Use your own TTS provider account inside Onepin. You keep your provider rates and relationship, and we handle routing, validation, and fixing on top. Available on Studio and above.
Not yet — open-source support is coming soon. Today we route across 30+ commercial models, picking the best one for each line.

Continuously. We benchmark TTS models across languages on a regular cadence, and the results feed straight into auto-routing, so the best model for each line stays current automatically.

One currency for the whole pipeline: generation, routing, and validation. 100 credits to the dollar. Each plan lists how many validated minutes that buys.
Included. One credit covers generation and validation together, with no second TTS invoice. We route each line to the best model and pass generation through at cost.
