Does the way a language is spoken vary with the age of the speakers of that language? In this paper we want to discuss different forms of articulatory relaxation in the Ile-de-France area in relation to the age of the speakers of those forms. The study shows that everybody relaxes his or her pronunciation in informal sttings. Only the reduction of "speach markers", such as 'écoute', 'je ne dis pas', seems to be specific to 18-45 year-old speakers.
