I'm a beginner in French and I'm learning pronunciation in French with this book. Would anybody come up with any good books/resources which contains the rules of pronunciation of different verb (in each conjugation) forms?
Not a book, but an excellent resource for pronunciation guidelines is forvo.com. You can search for almost any word with pronunciations recorded and submitted by (supposedly*) native speakers.
Some examples for a verb (jouer - all present tense forms + past participle, imperfect and future):
As you can probably here, there is little to distinguish between quite a few of the verb forms, especially joue, joues and jouent.
(* I say supposedly because, as far as I'm aware, you don't have to be native. It's always a good idea to try and find more than one recording / cross reference just to make sure you're not learning a non-standard accent etc.)
