Onepin

Onepin is an AI voice production agent that improves the accuracy of AI voiceover. It works with voices you already use, including ElevenLabs, OpenAI, Google, and 30+ more providers. Onepin spells out prices and dates, verifies names against a 4M-word pronunciation dictionary, scores every line, and corrects wrong words without re-rendering the take. It supports multiple languages and is aimed at teams producing voiceover for product videos, dubbing, and courses. It is free to start with no credit card required.
