Mycroft Mark II

Mycroft Mark II is a open voice assistant from Mycroft, catalogued as Open voice assistant in the Voice satellites & mic arrays meta-category. Its primary job is voice satellite or mic array for builders who need an inspectable path rather than a sealed appliance. In practice it targets: Far-field wake word + duplex Assist; Hardware mute / LED feedback; and AEC / beamforming on DSP.

Openness is listed as open. Technology notes in this catalog point to: ESP32-S3 + XMOS (XU316/XVF3800); ESPHome / openWakeWord / Assist; and I2S + Grove/HAT expansion. Heavy models usually sit on a phone, SBC, or edge box; the device itself is the sensor, array, camera, brain, or actuator surface depending on class.

For an agentic operating system this is a room-level voice front end: wake-word and duplex audio can carry proposals and confirmations without a closed smart speaker. Catalog possibilities include Room voice front-end for agents; and Robot ears / DoA.
