The International Dialects of English Archive (Meier, P., 1997)
http://www.dialectsarchive.com/
The International Dialects of English Archive was established by Paul Meier in 1997. It is the first online archive of primary-source recordings of English dialects and accents as heard around the world. All IDEA’s recordings are in English, including both English dialects and English spoken with other accents. The archive currently houses more than 1000 recordings by native speakers from different countries. Each recording includes both a reading and some unscripted speech-totaling about four minutes.
Speech Accent Archive (Steven, W., 2011)
http://accent.gmu.edu
The speech accent archive was established by Prof. Steven H. Weinberger in George Manson University in 2011. This speech corpus provides a large set of speech samples from a variety of language backgrounds. Both native and non-native speakers of English read the same paragraph and are carefully transcribed. Users can compare and analyze the accents of different English speakers using this corpus.
