The Speech Accent Archive is a website that compares different English accents.This website looks like Map your Voice that I have covered in an earlier post except that this latter offers an interactive map where you can check others accents or add up yours. The Speech Accent Archive is normally a study carried out by Geoge Mason University that aims at aggregating and comparing accents of non native speakers. Participants both native( Scottish/ Irish ) and non native, were asked to read out parts of a paragraph. These readings were then recorded and later on compared to American Accent.
Currently The Speech Accent Archive has over 600 different samples with around 200 different accents. if you want to hear how anyone from any particular nation speaks English you can access the archive of this website and you will be amazed at the grandeur of this work.
