Anyone has advice to improve my 'r' sound. Its sounds kinda like a french-accent r, coming from the throat. I've been trying forever to make a nice rolling r, but its not working at all.
In order to trill the r, the tongue tip must strike the alveolar ridge (the area right behind the upper front teeth) several times in rapid succession.
It is not an easy sound for English speakers, but it can be learned. Did you play with toy cars as a child? How do cars go? (Don't use your lips.)
Do the following drill twice a day (when you get up, before going to bed) for 5 minutes or so. (Lips must not touch!)
carro - rosa - perro - corro - barra - cerrado - enterrado - Roberto
You will improve with time.
