Speech recognition

Can we use Arduino uno board to make project in speech recognition? If yes, please explain in detail.

Forget it. Even with a huge fast processor it's very difficult. And the arduino series ( even a due) is a little slow one



I would doubt it, due to the lack of processing power. If you need it as part of your project, you can use the speech APIs in your smartphone or browser to do the speech part, and then send the control signals you want to the Arduino to do what it is good at.

If you want to keep it simple, you can do speech recognition in your browser like this demo. I have used that on a smartphone to control an Arduino.
