It has been claimed that in Parisian French high and mid front vowels in utterance-final open syllables are often devoiced and pronounced with a fricative-like noise. We investigated this phenomenon in spontaneous and read speech samples recorded from three generations of Parisian French speakers. Acoustic measurements indicate that the majority of vowels in read speech samples are at least partially devoiced, and show noise between 2-4 kHz. Devoicing and closure occur only in vowels that are in Intonation Phrase final position, and carry a low IP boundary tone. Male speakers in conversation showed the least devoicing. In reading and in conversation, 61 to 87 year-old speakers devoiced the target vowels as often as younger speakers did. We interpret the devoicing and closure of the vowel as the effect of an increased articulatory release before pause.
