AB  - OBJECTIVES: The present study had 2 main objectives: (1) examine the effect of 
      Parkinson's disease (PD) on vowel and consonant duration in French read speech 
      and (2) investigate whether the durational contrasts of consonants and vowels are 
      maintained or compromised. RESULTS: The data indicated that the consonant 
      durations were shortened in Parkinsonian speech (PS), compared to control speech 
      (CS). However, this shortening was consonant dependent: unvoiced occlusives and 
      fricatives were significantly shortened compared to other consonant categories. 
      All vowels were slightly longer in PS than in CS, however, the observed 
      differences were below the level of significance. Despite significant shortening 
      of some consonant categories, the general pattern of intrinsic duration was 
      maintained in PS. There was slightly less agreement for vowels with the normal 
      contrast of intrinsic durations, possibly because vowel durational contrasts are 
      more sensitive to PD disorders. CONCLUSION: Most PD patients tended to maintain 
      the intrinsic duration contrasts of both vowels and consonants, suggesting that 
      low-level articulatory constraints operate in a similar way and with the same 
      weight in PS and CS.
