Need Help

Im trying to create a robot that can recognize faces and greet them. I also want the robot to be able to recognize voices and answer with pre programmed responses. I've been searching for hours but I simply don't know what sensors to use. Can anyone help me?

It is very very unlikely that you can do either of those functions with an Arduino. Facial recognition (computer vision) and sophisticated audio processing needs more processing power.

Tried Google on Your title, “Need Help”?

I am pretty sure Rpi can do facial recognition

Yep. You need a camera and a microphone.

The ESP32-CAM is cheap and can do facial recognition.

A Title that summarises your problem would be more likely to catch the attention of people who have useful advice - for example "Suggestions for face and voice recognition for a robot". If you edit your Original Post you can change the title
