Prim Voices
Directable Speech Generation
Speech generation that takes direction like a voice actor.
We got frustrated with existing speech options
They were expensive. They required a subscription. The voices lacked range. They limited the number of voices we could use. So we made our own. Want to try it?

The Prim Voices Origin
At Prim Labs, we provide cutting-edge APIs for voice conversion and text-to-speech, designed to unlock creativity and simplify audio experiences for developers and creators.Our journey began with a heartfelt mission: creating Prim Stories, an app that connects families through story time. We wanted children to hear their favorite stories read by the familiar voices of loved ones—without the frustration of clunky recording workflows. Existing voice cloning tools were either prohibitively expensive for basic TTS or too rigid to allow creative direction. So, we built our own solution.The response was overwhelming. Realizing the potential beyond story time, we decided to release our technology as an API—scalable, affordable, and flexible enough to meet a variety of creative and technical needs.Today, Prim Labs empowers developers to harness the power of voice in entirely new ways. Whether you’re building family-focused apps, creative projects, or innovative voice-driven tools, our APIs are here to help.
