Does anyone know if this is viable on a pi zero?

No, based off of their hardware requirements. See here. https://rhasspy.readthedocs.io/en/latest/hardware/ https://rhasspy.readthedocs.io/en/latest/hardware/

  Apparently it's work in progress: https://github.com/synesthesiam/rhasspy/issues/61 https://github.com/synesthesiam/rhasspy/issues/61 Sounds like it's not too far off.

  Kaldi and Docker support are missing, but its possible to run on a Pi Zero using a virtual environment install: https://rhasspy.readthedocs.io/en/latest/installation/#virtual-environment https://rhasspy.readthedocs.io/en/latest/installation/#virtu...

You can set it up for remote processing and use a zero W as just a remote, but you will definitely need something more powerful for speech.

  AFAIK Snips.ai supports recognizing wake words on the pi zero w, and then have the actual speech recognition happen on some other machine. I guess something similar should be possible with Rhasspy? I was part way through a "smart speaker" project and planned to use Snips.ai, but I see now that they've been bought by Sonos so Rhasspy is looking pretty tempting now. However my plan was to use pi zero's at the speaker end, with my beefier HA machine doing the speech recognition.

    Definitely possible! See https://rhasspy.readthedocs.io/en/latest/speech-to-text/#remote-http-server https://rhasspy.readthedocs.io/en/latest/speech-to-text/#rem...

I managed to run Pocketsphinx on a pi zero w in 2018, wake words only

No, even on RPi 3 both pocketsphinx and Kaldi are very slow to the point of not being responsive enough for real use.

Yes, Rhasspy will now run on a Pi Zero (armv6l) as of 2.4.15 (https://community.rhasspy.org/t/version-2-4-15-release/115 https://community.rhasspy.org/t/version-2-4-15-release/115). Kaldi is not yet supported, so you have to use pocketsphinx for speech recognition. You'll also have to do a virtual environment install (https://rhasspy.readthedocs.io/en/latest/installation/#virtual-environment https://rhasspy.readthedocs.io/en/latest/installation/#virtu...) The recommended use of a Pi Zero is as a recording/wake word detection/audio playback satellite. Other functions, like speech/intent recognition can be done remotely (e.g., https://rhasspy.readthedocs.io/en/latest/speech-to-text/#remote-http-server https://rhasspy.readthedocs.io/en/latest/speech-to-text/#rem...)
