Technology
Parakeet V3 + ONNX
Uses NVIDIA's Parakeet V3 model optimized for local inference via the ONNX runtime.
On-device AI
On-device transcription for Windows
PrivaSpeech runs speech recognition directly on your Windows PC using Parakeet V3 AI models. Your voice is processed locally, not on remote servers.
What "on-device" actually means
On-device (PrivaSpeech)
- ✓AI model runs on your CPU
- ✓Audio stays on your machine
- ✓Works offline after setup
- ✓No audio sent to third parties
Cloud-based (typical services)
- ✗Audio streamed to remote servers
- ✗Processing happens in data centers
- ✗Requires constant internet
- ✗Data retention policies vary
Hardware
CPU-friendly
Works on modern CPUs without a dedicated GPU.
Privacy
No cloud dependency
After the initial model download, transcription doesn't require internet connectivity.
Technical details
~465MB download, stored locally on your PC
ONNX Runtime with CPU support
English (general vocabulary)
Windows 10/11, 64-bit
Why on-device transcription matters
When speech recognition happens on your device, you control where your audio goes. There's no need to trust a third party with potentially sensitive recordings.
On-device processing also means lower latency (no network round-trip) and reliable operation even when internet is unavailable.
The tradeoff: on-device models may be less accurate than the largest cloud models for specialized vocabulary. For most dictation tasks, the difference is manageable with light edits.
