Sound familiar?
The problems that show up in this work, every day.
Robotic voices fatigue users in minutes
Mechanical screen-reader voices wear listeners down, so people tolerate them rather than choosing to listen.
Recording a human voice cannot keep up
You cannot hire someone to read every page, update, and piece of dynamic content, so human narration stops scaling fast.
Cloud TTS sends user content off-device
Routing user text through cloud APIs creates a privacy and compliance exposure for every page read aloud.
Cloud round-trips add lag to every request
Network round-trips to a cloud service add delay that makes assistive playback feel slow and broken to the user.
Vois runs natural voice on-device, online or off
Natural-sounding voice that processes on-device. No cloud latency, no user content leaving the machine, and it keeps working offline.
