You can use Independent Components Analysis or Blind Source Separation. Sorry I don't have code but you can see these links:

i have gone through all the mentioned links but i could not get it. Can you explain a little more?

thank you.

No, sorry. It's not my field, and not my code.

Your problem in general is not an easy one. Maybe just search for "cocktail party problem".

I know it's not easy to learn that topic, but that's all I have to offer you. Whoever offers you anything -- it will not be easy or trivial, since it's inherently a difficult problem. Sorry.

Ok no problem. thank You for quick response

These examples might be helpful:

• Cocktail Party Source Separation Using Deep Learning
• End-to-End Deep Speech Separation

They show how to separate voices of two speakers speaking simultaneously. I believe both examples could be adapted for three speakers.
