AI voiceover with every name, price and date said right
AI voices sound human now. But they still guess names from the spelling, and nobody has time to listen to every line. Onepin runs on the voices you already use (ElevenLabs, OpenAI, Google, 30+ more), spells out prices and dates, checks names against a 4M-word pronunciation dictionary, scores every line, and fixes the wrong word without re-rendering the take. Built for teams shipping AI voiceover in several languages: product videos, dubbing, courses. Free to start, no credit card required.
Hey Product Hunt 👋 SB here, founder of Onepin. Thanks @rohanrecommends for hunting us.
A great AI voice reads "Porsche Taycan" as TAY-can. Porsche says TIE-kahn. It guessed from the spelling, and nobody caught it, because nobody listens to line 1,200.
We spent two years at Podonos measuring how AI voices sound, with 150,000 human listeners doing the rating. The models solved delivery. What kept failing was names, prices and dates, and the only check most teams run is a person with headphones.
Today we're launching Onepin, the production step after text-to-speech. It runs on the voices you already use, ElevenLabs, OpenAI, Google and 30+ more, and checks every line before it ships.
Here is what it does to every script: 🔢 Spells out prices, dates and abbreviations before the voice reads them. 📖 Checks names, brands and drug terms against a 4-million-word pronunciation dictionary. 📊 Scores every line for naturalness, clarity, word accuracy and pronunciation, against a bar you set. 🔧 Fixes the one wrong word in the same voice, without re-rendering the take.
Two decisions we made on purpose. Onepin checks how a name was said, not just what the transcript spells. And there is no box where you type phonetic spellings: the dictionary and the fix do that work, so your script stays as written.
Built for anyone shipping AI voiceover at volume: product videos, ads, explainers, dubbing, audiobooks, courses, and platforms that put a voice in front of millions of users. API, SDK and MCP from day one. SOC 2 Type II.
You keep your voice. Onepin makes sure it says the right words.
Free to start, no card: onepin.ai. You can run one line on the homepage without an account.

Who hunted Onepin?
Onepin was hunted by Rohan Chaubey. A “hunter” on Product Hunt is the community member who submits a product to the platform — uploading the images, the link, and tagging the makers behind it. Hunters typically write the first comment explaining why a product is worth attention, and their followers are notified the moment they post. Around 79% of featured launches on Product Hunt are self-hunted by their makers, but a well-known hunter still acts as a signal of quality to the rest of the community.
