Kacy, a Pi 5 voice assistant using Whisper, Claude and Piper
A Raspberry Pi 5 voice assistant uses local Whisper and Piper with the Claude API as its brain to control Home Assistant in about 2.5 seconds per request.
The full story
Over a few months the poster built a voice assistant called Kacy on a Raspberry Pi 5: local Whisper for speech-to-text, the Claude API (Haiku) as the brain, local Piper for a German voice, and the Home Assistant REST API to control lights, blinds and switches.
He measured about 2.5 seconds from speaking to hearing the answer. The hardest part was getting Piper to run reliably as a service and piping the audio, which took a weekend.
