Whisper Local API - Secure & Private ASR

Deploy a privacy-first, 100% local speech-to-text service in a deterministic way. This allows OpenClaw to process audio transcriptions safely on your own hardware without ever contacting third-party cloud APIs.

Key SEO & Security Features

• 100% Offline & Private: Your voice data, commands, and transcriptions never leave your host system. Zero cloud dependencies.
• Highly Accurate: Uses the large-v3-turbo model via faster-whisper, achieving state-of-the-art accuracy even with accents or background noise.
• Memory Safe: Operates around ~400-500MB of RAM, making it extremely lightweight for VPS or low-resource edge servers.
• OpenAI API Compatible: Exposes a strict /v1/audio/transcriptions endpoint mimicking OpenAI's JSON format. Compatible natively with any software that supports OpenAI's Whisper API.
