About Syllivo
What Syllivo does
Syllivo turns text into spoken audio, entirely in your browser. You write a script, pick a voice, and generate audio you can listen to and export. It works in Hindi, English, and Hinglish, and it is built for a normal phone as well as a computer.
On-device, by design
There is no cloud voice server in the loop. Voice files download once, are verified, and stay cached on your device; the voice model loads for a job and is unloaded from memory when the job finishes, succeeds, fails, or is stopped. Your scripts and audio stay in your browser's local storage.
Voices, named honestly
Voices are named by what is verified about them: the everyday voices by gender and official number (Male 1 to Male 5, Female 1 to Female 5), and the American and British voices by accent and official name. Custom Voice has no preset voices — it works only from a reference recording you supply. No personality labels are invented for any voice, and Hindi support is partial for some voices.
Unlimited, and its limits
Unlimited means no artificial character or per-generation quota. The practical limits are device speed and storage, and generation stops when the browser closes. There is no subscription in this build, no ads yet, and the option to remove ads is Coming Soon.
The blog
The Syllivo blog publishes practical notes on on-device voice generation, choosing a voice, and writing scripts that sound good. Posts claim only what is actually true about the app.
