> Modeled after the Wyoming Satellite two‑mic tutorial, adapted from actual shell history.
This guide reproduces a working setup of the **linux-voice-assistant** project with **Wyoming OpenWakeWord** or **MicroWakeWord** on a Raspberry PI Zero 2W and a Respeaker 2‑mic HAT (e.g., seeed-2mic-voicecard). It assumes a fresh system with sudo access and the default "pi" user. Included is the option to use PipeWire or PulseAudio instead of ALSA.
