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.

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.
