What does tonvio do?
tonvio is an AI text-to-speech service that converts written text into spoken audio. Paste your content — up to 100,000 characters per job — choose from more than 14,000 voices, and tonvio produces an MP3 file ready for download. The first voiceover is free, letting you try it without risk. The tool is built for long-form projects: audiobooks, podcast episodes, YouTube voiceovers, and online course narration.
The voice selection is comprehensive. You can filter by gender, age, language, and character type. Each voice has a live preview so you know exactly what it sounds like before generating. For audiobooks, tonvio keeps a consistent narrator tone across chapters and automatically assembles the audio. There’s a job queue and generation history on your dashboard. A role-based dialogue feature — still in development — will split text by character and assign different voices to each speaker.
Authors who want to turn their manuscripts into audiobooks will find tonvio useful. Podcasters can produce intros, ads, and full episodes. Educators can narrate lessons and lectures. The interface is straightforward: paste, pick a voice, and download. No audio editing skills required.
