3D printed rover controlled by voice

It’s probably not the most useful way to use a voice assistant (but why not later?), but I’ve built a small rover based on a NodeMCU (programmed with esphome) and 3 SG90 motors. It’s inexpensive (less than €10), easy to print, and expandable afterward.
I’ve started a youtube tutorial (in french, sorry) :

So, I would like to control it by voice:

Move forward one meter
Move forward 30 centimeters
Turn to 10 o'clock
Turn to 2 o'clock

I think I’m almost there, but how do I input numerical parameters into my voice commands? Is it possible?
Thank you!

nice work on this

Finally, it works !
