Perception and production of voicing contrasts in children with cochlear implants (In Greek)

Research on VOT production of stops in children with CI vs NH has reported conflicting results. Effects of age and place of articulation on VOT have not been examined for children with CI. The purpose of this study, presented in this book, was to examine VOT production by Greek-speaking children with CI in comparison to NH controls, with a focus on the effects of age, type of stimuli, and place of articulation. Also, perception of VOT was examined. In perception, lower performance was found for children with cochlear implants in comparison with children with normal hearing. In production, for voiced stops, which demand more articulatory effort, children with CI showed longer VOT than children with NH whereas VOT for voiceless stops was similar to NH peers. Also, in both voiced and voiceless stops the VOT differed as a function of age and place of articulation across groups. Differences as a function of stimuli type were only noted for voiced stops across groups.
