Rhasspy
Offline private voice assistant for many human languages
...Rhasspy will produce JSON events that can trigger action in home automation software, such as a Node-RED flow. Rhasspy comes with a snazzy web interface that lets you configure, program, and test your voice assistant remotely from your web browser. All of the web UI's functionality is exposed in a comprehensive HTTP API. You can easily extend or replace functionality in Rhasspy by using the appropriate messages. Many of these messages can be also sent and received over the HTTP API and the WebSocket API. Rhasspy is intended for savvy amateurs or advanced users that want to have a private voice interface to their chosen home automation software.
