They were acquired by Sonos. A few months ago they were offering tools to build your own speech recognition agents.

Before they were bought, you could build (with the help of a WebApp hosted by them) an offline usable speech recognition module, that could comfortably run on a Pi, and that would output parsed sentences in JSON format onto MQTT. Easy to integrate with everything in IOT. I loved it. Now i'm also looking for an alternative for the Speech-to-text(-to-json) part, like you.
