Pronunciation can give new learners headaches. English has sounds not present in other languages and to add to the difficulty, there are differences in dialects even within the same country. To get an idea of how different it can be, visit the Speech Accent Archive and IDEA (International Dialects of English Archive). Both have a large sample of English speaker's accents from around the world. The former includes both native and non-native English speakers and the latter includes native speakers only.
The following tabbed list contains summaries and/or definitions of pronunciation terms. For those interested in more in-depth information on the subject, see the provided links.
The first three contain charts for English pronunciations (based on dialect).
The next two are articles on how a person's native language influences learning and pronouncing English.
The next four define the standard dialects/pronunciations of English with pointers to complete articles.
The last one contains pointers to other articles on English dialect that might be of interest.
