Rhasspy – Offline private voice assistant for many human languages
Discussed 3 years ago [1]. See also the docs [2] and board [3].Wanted to post this as currently Alexa and Mycroft are being discussed, but I have not seen a mention of this project. It is offline first, compared to Mycroft which relies on cloud services by default, even if you seem to be able to run it completely offline.To share my personal experience with it, I am impressed with how well it can handle the basic commands I need (lights on/off, music control). It also features a reliable and easy satellite integration, so I can do the heavy lifting (STT and TTS) on my home server and only keep wakeword and sound input/output on the RPi. Different than Alexa, you define each command ("sentence") yourself, which seems to really help with the recognition accuracy. It also means you have no problem of discovering all available commands.I have it integrated with Home Assistant for some basic automation. Essentially each sentence sends off a command to Home Assistant with the recognized text and an ID. You can also send back text that is then spoken by Rhasspy. For reference, I am using Porcupine as wake word engine ("Computer"), Kaldi as STT, Fsticuffs as intent recognition, and Larynx as TTS (voice "harvard"). The home server is a desktop PC, the satellite currently runs on an RPi 4 with about 2-10% load.[1] https://news.ycombinator.com/item?id=21926027
