I would say English uses more, or greater, volume to create emphasis, though the overall pitch may be lower. Greater volume results in a higher pitch. I have a pronunciation student from India. I advised him to try to use a lower pitch in general for his overall intonation. In general, I think American English uses a lower pitch. Of course, this varies from speaker to speaker.
Thanks for the information about speakers of Hindi who speak English. I think it will prove to be helpful somewhere down the line.
