When it comes to speak, both are 99% percent exactly same. Just a few words are make difference. But writing are completely different. Speakers of both can easily understand each. I am a native urdu speaker and communicate with native hindi speakers at my work place without any problem. What you intend to you. Can I help you with learning spoken Hindi/Urdu. In return I would like you to help me in learning spoken English. Do get back to me. Regards,
