I’m afraid my keyboard isn’t set up to write such a long text in IPA, but here’s the trick: We put the primary stress on the last name in each case. For the famous ones, you can check an encyclopedia or dictionary — that will usually show the pronunciation. Otherwise, your guess is as good as most native speakers’ guesses — we read names the same as we read English words. Thus, “Chaucer” rhymes with “saucer”. There are of course some places where names have a more conservative spelling, for example “Geoffrey” is pronounced the same as “Jeffry”. Some of those names have additional silent letters, such as the “e” in “Wilde” and the second “o” in “Woolf” (or perhaps the common noun “wolf” lacks an “o”…). In “Charlotte Brontë”, the “e” in the first name is silent, but the “e” in the last name is usually pronounced /i/ (which is why we often write it with a dieresis). “Vidiadhar Surajprasad” looks like a name from India, but again, your guess is as good as an American’s.
