Rhasspy (pronounced RAH-SPEE) is an open source, fully offline voice assistant toolkit for many languages that works well with Home Assistant, Hass.io, and Node-RED.
You specify voice commands in a template language:
[LightState]
states = (on | off)
turn (<states>){state} [the] light
and Rhasspy will produce JSON events that can trigger actions in home automation software or Node-RED flows:
{
"text": "turn on the light",
"intent": {
"name": "LightState"
},
"slots": {
"state": "on"
}
}
Rhasspy is optimized for:
- Working with external services via MQTT, HTTP, and Websockets
- Home Assistant and Hass.IO have built-in support
- Pre-specified voice commands that are described well by a grammar
- You can also do open-ended speech recognition
- Voice commands with uncommon words or pronunciations
- New words are added phonetically with automated assistance

Intended Audience
Rhasspy is intended for advanced users that want to have a voice interface to Home Assistant, but value privacy and freedom above all else. There are many other voice assistants, but none (to my knowledge) that:
- Can function completely disconnected from the Internet
- Are entirely free/open source
- Work well with Home Assistant, Hass.io, and Node-RED
If you feel comfortable sending your voice commands through the Internet for someone else to process, or are not comfortable with rolling your own Home Assistant automations to handle intents, I recommend taking a look at Mycroft.
