[Open Source] Android voice assistant with offline wake word (Vosk) + OpenClaw gateway

I open-sourced an Android voice assistant app built for OpenClaw.

Repo: https://github.com/yuga-hashimoto/openclaw-assistant

Technical highlights:

• Offline wake-word detection (Vosk)
• VoiceInteractionService integration
• Real-time streaming via OpenClaw gateway
• Encrypted local settings (AES-GCM)
• English / Japanese UI

Looking for feedback on architecture, reliability, and Android UX.
