I have already written that I assembled a Google assistant on a raspberry pi ($30) and Google voice kit ($5). It works quite nicely. The microphone is very sensitive, and the speech recognition is simply a notch better than even on an iPhone with Siri. Apparently, due to the “special hardware” – the VoiceHat boards from the $5 kit.
Convenient features include: timer, traffic, weather, shopping list. Inconvenient features include: calendar, mail, messages, and broadcast are not supported. It’s also good to have an Android phone rather than iOS alongside this device.
