Clarté de la parole et effets coarticulatoires en arabe standard et dialectal (Speech clarity and coarticulatory effects in standard and dialectal Arabic) [in French]

_________________________________________________________________________________________________________ Speech clarity and coarticulatory effects in standard and dialectal Arabic This study deals with the co-variation of speech clarity and coarticulatory patterns. Two experiments were conducted to investigate the influence of two parameters, the speech style (formal vs. non formal) and the prosodic position (stressed vs. unstressed syllable). The speech material was composed of three word lists varying CV syllable contexts with pharyngealized /t d s / vs. nonpharyngealized consonants /t d s / in Modern standard Arabic and dialectal Arabic. Acoustic materials revealed evident relationship between speech clarity and coarticulation: more coarticulation in formal speech and in strong prosodic position.
