Narrative:
We were assigned the deauville 4W arrival to lfpg with a speed and altitude restr at merue. Between the radio frequency issue and strong accent of the controller; it was our understanding that after merue we were cleared direct cgn; and the FMS was programmed as such. However; when we proceeded direct to cgn; ATC queried us as to why we were off track. I responded with the clearance we understood was correct; but he gave us a heading direct to crl and advised us we were off course. The french controllers were extremely difficult to understand; but we should have requested clarification on the routing when we were given the STAR. There were no traffic conflicts.

Narrative: WE WERE ASSIGNED THE DEAUVILLE 4W ARR TO LFPG WITH A SPD AND ALT RESTR AT MERUE. BTWN THE RADIO FREQ ISSUE AND STRONG ACCENT OF THE CTLR; IT WAS OUR UNDERSTANDING THAT AFTER MERUE WE WERE CLRED DIRECT CGN; AND THE FMS WAS PROGRAMMED AS SUCH. HOWEVER; WHEN WE PROCEEDED DIRECT TO CGN; ATC QUERIED US AS TO WHY WE WERE OFF TRACK. I RESPONDED WITH THE CLRNC WE UNDERSTOOD WAS CORRECT; BUT HE GAVE US A HDG DIRECT TO CRL AND ADVISED US WE WERE OFF COURSE. THE FRENCH CTLRS WERE EXTREMELY DIFFICULT TO UNDERSTAND; BUT WE SHOULD HAVE REQUESTED CLARIFICATION ON THE ROUTING WHEN WE WERE GIVEN THE STAR. THERE WERE NO TFC CONFLICTS.
