Voice Commands - Recommended Route

Hi;

We wish to add voice commands to our RPi 3 powered robot. Needs to be simple and without the need for a HAT.
To avoid going down a rabbit hole , where should we start looking?

Re: VNC Retropi

Last time I was working on this, I got as far as just about everything running except I could not control it remotely. I still needed a controller connected to the PI itself. Was there an update that has resolved this or is there a workaround required? See this tutorial: https://www.linux-projects....

Raspberry Pi 4 1 or 2GB

Hi;

We are buying some Pi 4s for our Pi Jam.
Just checking, is the 1GB versions OK? e.g. is this enough base memory for things like Scratch, Python Rolling Robots, Minecraft etc. We will not be running high level graphics just projects for children / adults at the monthly Pi Jam.

Thanks
