> This means a Raspberry Pi and some other platforms such as the Respeaker core or the Matrix Creator is the best choices for a hardware platform. As for which Raspberry Pi, a raspberry 3, 3b, 3b+, 3A+ or 4 for the main unit are good choices.
Extrapolating on the expected hardware, it's likely going to be either inaccurate, have very high latency, or both.
Even Mycroft which open sourced everything else still runs the voice recognition part in the cloud because it's not possible to host it locally without rather beefy hardware that the average user won't have around (and even that has high latency). I did try some offline speech to text alternatives for it but they all more or less sucked to be frank.
Google Assistant and Siri have offline functionality so it must at least be possible, but perhaps needs a company's worth of machine learning thrown at it
