Why security matters in voice to text
Cloud dictation tools upload your audio to external servers to process it. That is how they work. VoicePrivate does not.
When you dictate into a cloud-based tool, your audio leaves your device. It travels over the internet to a remote server. A third-party model processes it. The transcript comes back. Your audio may be stored, used for model training, or retained for compliance with data laws outside your control. You are trusting a policy, not an architecture.
VoicePrivate works differently at the level of how the software is built. The AI that converts your speech to text runs on your device's own CPU or GPU. No audio leaves. No transcript is transmitted. There is no network call to intercept, no server to breach, no third party in the chain.
Three architecture-based security guarantees
These are not policy commitments. They are structural properties of how the software is built.
Zero outbound connections during transcription
VoicePrivate makes no network requests when processing your speech. You can run it with your WiFi off or block it in your firewall; nothing changes. No DNS lookups, no HTTP requests, no WebSocket connections during a transcription session.
Local AI model on your device
The speech recognition model runs entirely on your computer's CPU or GPU. It is a Whisper-based model with weights stored locally after installation. No API key, no cloud dependency, no remote inference call. Your audio is processed where it is captured.
Encrypted local storage
Transcripts are saved to an encrypted SQLite database on your machine. The data does not leave your device. Access requires your local credentials. Nothing is synced to a cloud account or backed up to external storage by default.

Who uses secure voice to text
Anyone who dictates content they would not want on a third-party server.
Local vs. cloud architecture
The security difference is not a feature. It is a consequence of where computation happens.
| Property | VoicePrivate (on-device) | Cloud voice tools |
|---|---|---|
| Where audio is processed | Your device | Remote servers |
| Audio retained after transcription | Never retained | Often retained |
| Works without internet | Fully offline | Requires connection |
| Account required | No account needed | Account required |
| Third parties in the processing chain | None | At minimum one |
