This site has a person say aloud the words or sentence that you have typed in. Try typing in her name http://www.oddcast.com/home/demos/tts/tts_example.php?sitepal

The surname is pronounced "Jaa-gohs". The syllables are both long and the 'e' is silent. I found an interview where she was introduced: http://www.youtube.com/watch?v=b9706tX0nlE

Well, google translator is not a very effective tool.... but has got a really useful feature... on the right bottom, you have a button with a picture of a speaker. Clicking on it, you will hear the pronunciation...
