Long sessions: uploads vs 30‑second windowing

Why streaming on‑device and finalizing only the last ~30 seconds keeps long dictations responsive.

Half an hour of clean audio is not a “quick upload.”

Uploading long, high‑quality audio takes time, especially on variable wifi. Many cloud tools avoid heavy compression to protect accuracy, which increases upload size.

Voice Type stays on‑device, streams continuously, and when you stop, finishes only the last ~30s window (≈2–3s on an M1). That’s why long sessions feel snappy in practice.
