Author here, happy new year HN! Glad to answer any questions (also see https://community.rhasspy.org)

Bit of background: Rhasspy was originally designed for Home Assistant (https://www.home-assistant.io), but now works with lots of home automation projects (Hass.io, Node-RED, OpenHAB, Jeedom). Its sister project, voicej2son (http://voice2json.org), is for command-line use and has fewer options.

With Snips.ai being bought by Sonos, we're now focusing on compatibility with its MQTT protocol (https://docs.snips.ai/reference/hermes) so existing plugins/skills will just work. Supporting Snips-like number/duration/dateTime slots across over a dozen languages is going to be a major challenge, so please reach out if you speak a language besides English* :)
