Abstract
Aims: (a) To study the structure of protophones of spontaneous
speech of two implanted children and classify them via
acoustical analysis of their suprasegmental features; (b) to track a
developmental order of infant vocalizations.
Material and Methods: The spontaneous productions of two Greek
implanted children (ages: 1:10–2:7, post-implant ages: 0:0–0:11)
were examined. Over a span of six months an extensive record
of protophones was transcribed via the IPA. Duration and pitch
contour were analyzed via PRAAT. Utterance characteristics were
analyzed in relation to a) children’s age b) post-implant age.
Results: Certain developmental classification schemes emerged via
the multi-level phonological analysis. The structure of protophones
depended upon implantation age since the younger, earlyimplanted child showed more complex patterns. Consonant-vowel
sequences were established by the post-implant age of six months.
Conclusions: The analysis of protophones can serve as a prognostic
indicator for the detection of other disabilities in implanted
infants/toddlers
