Remember that to say please, you're welcome in Hindi, you say कृपया (krpaya), आपका स्वागत है (aapaka svaagat hai).
To ask if someone speaks Hindi, you say:
क्या आप हिंदी बोलते हैं? (kya aap hindee bolate hain?) which sounds like kee-yah ah-p hin-dee boh-lah-tay hay-n 文A
To say yes you would say हां (haan) which sounds like hah 文A
or to say no you would say नहीं (nahin) which sounds like neh-hee 文A
