Is there any website providing speech varieties audios?

i am a linguistics student in a university in Thailand. I'm conducting a research on people's attitudes toward varieties of English speech. The problem is i have difficulty recording speech varieties by myself due to limited number of American, British, Indian speakers in where i'm studying. Is there any website that provides audios of varieties of English? (speakers speak in the same passage) I focus on 6 main varieties: American, British, Indian, Filipino, Chinese and Thai based on Kachru's three concentric circles of English use in the world. Thank you in advance sharp
