tonvio

tonvio positions itself as a complete voiceover studio in the browser rather than a single-purpose text-to-speech box. Users paste a script, story, or book chapter — up to 200,000 characters depending on plan — and the platform assigns a narrator voice while automatically splitting multi-character dialogue so each character speaks with a distinct voice. Previews and filters by language, gender, age, and genre make it easy to audition a voice before committing, and finished files land in a history with queueing for long jobs.

Beyond plain narration, tonvio covers workflows that usually require several separate tools. Voice cloning lets you record or upload a short sample (roughly 10–60 seconds) and then voice any text in your own voice, with the clone kept private to your account. Translation-and-voiceover produces a translated script and a matching audio track for up to three languages at once while keeping the original. Bulk voiceover handles up to 20 texts in one group, each with its own voice and settings, and a REST API with keys and limits lets developers build generation directly into their own applications.

Pricing is built around two models. Unlimited subscriptions start at $29.99 per month and remove any monthly character quota, charging instead for generation speed (the higher tier doubles parallel streams and raises the per-job character ceiling). For occasional users, one-time credit packs run from 100,000 characters for $1.50 up to 15 million characters for $35, and credits never expire. Note that character dubbing and translation require an active subscription, and crypto is the only accepted payment method. Every new account receives a one-time 10,000-character welcome bonus that can be used on any feature.
