A very good tool is provided by http://www.aussprache.at
In the Window "Suche" you can search for a word (example: search for »Chemie«). The findings are shown in the window above (for »Chemie« you find »Alchemie«, »Biochemie«, »Chemie« and »Chemielaborant«). Click on one of those findings.
Left of this window you find the pronunciation written in IPA-characters for Austrian German (flag: red-white-red), German German (flag: black-red-gold) and Swiss German (flag: white cross on red ground).
And left of each written pronunciation you have two buttons to hear it. The red button is a female voice, the blue a male voice.
All six speakers are native speakers of their variation of German Language, and each speaker is a professional speaker. (I can only identify the Austrian voices, they are both speakers in Austrian Radio and Television.)
When you compare the pronunciations in different countries, you often will find that there are differences (like the pronunciation of »ch« in »Chemie«, the »ä« in »Käse« or the »s« in »Wiese«), but they are all correct and used in the respective country.
