dictionlabs/gateway repository overview

⁠Diction Gateway

Open-source streaming gateway for Diction⁠, the iOS keyboard for voice dictation. It sits between the Diction app and your speech-to-text backend: WebSocket streaming, AES-256-GCM end-to-end encryption, and optional LLM cleanup. Point it at any OpenAI-compatible transcription server, self-hosted or otherwise.

• Self-hosted in one command. docker compose up and paste the URL into the app.
• Model-agnostic. Speaks the OpenAI transcription API. Works with any compatible backend.
• Zero tracking. No analytics, no telemetry. Audit the source yourself.
• Free and unlimited. No caps, no rate limits, no expiry.

⁠Quick start (NVIDIA GPU)

Parakeet TDT 0.6B v3⁠ transcribes a 5-second clip in well under a second on a consumer GPU. Covers 25 European languages. Requires the NVIDIA Container Toolkit⁠ on the host.
