    OpenWakeWord (the solution I also use in my Platypush setup) is actually very good at hotword detection, especially when paired with libspeex for noise suppression.

    The STT models from Vosk are actually quite good too. The 180 MB English model is light enough to run on a RPi and it’s actually quite decent with clean accents. They also have a 1.8 GB model that is very accurate and that actually can still run fine on a RPi5 8 GB.

      Don’t misunderstand. Openwakeword works great. I just think it’s awesome that the hotword detection can run so well directly on low powered devices now.

      About STT I’ll agree that they can run well, I just found the experience a lot better on a heavier model running on a beefier machine. They do well in a silent space but struggle when you add background noise.
