Hearing loss affects both speech perception and production with detrimental effects on various speech characteristics including coarticulatory dynamics. The aim of the present study is to explore consonant-to-vowel (C-to-V) and vowel-to-vowel (V-to-V) coarticulation in magnitude, direction and temporal extent in the speech of young adult male and female speakers of Greek with normal hearing (NH) and hearing impairment (HI). Nine intelligible speakers with profound HI, using conventional hearing aids, and five speakers with NH produced /pVCV/ disyllables, with the point vowels /i, a, u/ and the consonants /p, t, s/, stressed either on the first or the second syllable.
