Percept Listen

Captures ambient audio from wearable devices, transcribes locally, and streams searchable, speaker-tagged conversation data to your OpenClaw agent.

Ambient audio capture and transcription for OpenClaw agents via wearable devices.

What it does

Connects a wearable microphone (Omi pendant or Apple Watch) to your OpenClaw agent. Audio is transcribed locally and streamed as structured conversation data — speaker-tagged, timestamped, and searchable.

When to use

• User wants their agent to hear ambient conversations
• User asks to "start listening" or "turn on the mic"
• User mentions Omi pendant, wearable, or ambient audio

Requirements

• Percept server running locally (pip install getpercept && percept start)
• Omi pendant paired via phone, OR Apple Watch with Percept app
• Webhook configured: Omi app → Settings → Webhooks → https://<your-tunnel>/webhook/transcript

Setup

# Install Percept
pip install getpercept

# Start the receiver (default port 8900)
percept start

# Or run directly
PYTHONPATH=. python -m uvicorn src.receiver:app --host 0.0.0.0 --port 8900

Configure a tunnel (Cloudflare, ngrok, Tailscale) so Omi can reach your local server.

How it works

1. Omi pendant captures audio → phone does STT → sends transcript segments via webhook
2. Percept receiver processes segments into conversations
3. Conversations are stored in local SQLite with FTS5 full-text search
4. All processing stays local — no audio leaves your machine

Data locations

• SQLite DB: percept/data/percept.db
• Live transcript: /tmp/percept-live.txt
• Conversations: percept/data/conversations/

Configuration

Wake words, speaker names, and all settings are managed via the Percept dashboard (port 8960) or directly in the SQLite database.
