On-Device Voice Guide
On-device voice generation means the speech is made where you are, not on a distant voice server. In Syllivo, you write a script, pick a voice, and your browser does the work using voice files that were downloaded once and stored on your device.
Why on-device matters
Privacy is the practical benefit: your script and your audio never travel to a voice-generation server. The trade-off is equally practical: a phone has limited memory and storage, so Syllivo loads a voice model for a job and unloads it from memory when the job finishes, succeeds, fails, or is stopped. Your projects and finished audio stay saved locally; only the in-memory model is freed, and the next generation reloads it from cache.
What unlimited means here
Unlimited means no artificial character or per-generation quota. It does not mean unlimited memory, unlimited length on every device, or generation that continues after you close the browser. Device speed and storage are the real limits, and sections you have already generated are saved so you can resume.
How to use this guide
Start with the overview post below, then try a short generation on your own script before running anything long. If a passage sounds unclear, rewrite it first — shorter sentences and cleaner punctuation fix more problems than any setting does.
