There are many other differences in addition to those G.M. correctly listed, e.g. words ending in -e are softened with a consonant (Suppe => Suppm, Tasche => Taschn), or the ending -erl is added quite frequently to make diminutives (Flasche => Flascherl, Türe => Türl). Moreover, there are so many words that are not just pronounced differently, but that are different because of a different ending, e.g. viel => vui , will => wui. And then there is a whole dictionary of different vocabulary, but that is of course a separate topic. The differences between regional accents and dialects of German fills books and you would have to look at each and every region individually, such as Vorarlberg, Tirol, Salzburg, Oberösterreich, Niederösterreich, and the one that sounds like a completely different language: "Wienerisch" (German spoken in Vienna).
If you are looking for more academic and concise literature on this topic, you may want to study the vowel shifts that have occured in German or read some of the publications by Rudolf Muhr (Association of Austrian German/ Austrian German Research Centre), such as his paper on "The Pronouncing Dictionary of Austrian German (AGPD) and the Austrian Phonetic Database (ADABA): Report on a large Phonetic Resources Database of the three Major Varieties of German".
