Would I have an accent to them ?

hi

I’m german native speaker. If you try to speak french, native french speakers will tell you, you have an english/american/whatever accent. If you try to speak german, native german speakers will say you have got an english/american/whatever accent.

If you speak english to a native french or german speaker, they will assume you speak ‘correct’ english and will try to imitate your pronounciation.

If somebody from france or germany has very, very much practice speakin english, he might be able to hear the difference between scottish, a yankee, an oxford-english, a texan and an australian accent. It takes even more practice to be able to imitate those different accents. After all, many native speakers can’t.

Some people never get rid of their accents, even after 40 years of being expatriate. (Look at Arnold Gouvernator.)

You probably wouldn’t hear the difference between a Parisian and a mediterranean Frenchman. The French do.
