Absolutely not. Even if you could run python on the Uno (I think there are some beefier boards, that can run micropython), it wouldn't be capable enough (speed and memory) to lift the heavy duty of a virtual assistent. Speech recognition is way out of it's range. But even for capturing the voice, sending it to a web based speech recognition, processing the ...

At this moment Arduino cannot run python. Python is to resource heavy for a simple ATMega processor. I suggest RaspberyPi, of Onion Omega2. They are compatible with PCs and have a python interpreter on them.

In case anyone is looking for a solution, I followed the TL071 manual (texas instruments) for an op-amp instead of using the diagram posted above. That signal then links into a bias. The noise was coming from having 5V shared with the LED lights (WS2812B). Once I put them on a different circuit (shared ground) it was ok.

I did it on HC-05 (reflash to RN-42) and use HID profile to send command: Play/pause fwd/rwd vol+/- I can post sample code if needed.

The TLO series don't work with 5v supply. They have also a reversal phase : that meens, when used in follower, it's output will go high when intut is lower than 3v... One can use an old LM324 or LM358, but output is not going up to VCC... OPA140 is a correct choice. Also, may be a link capacitor of 100µF between input and potentiometer is necessary : this ...
