“…The Greek language study (Binos et al, 2020). Binos et al, (2020), analyzed vocant productions based on spontaneous vocalizations using a combination of acoustical and auditory characteristics. Reflexive or vegetative sounds were excluded.Our CI participants had deafness of unknown etiology and no other disabilities and were enrolled in auditory-oral programs.…”

“…The vocant onset and offset were measured via wideband spectrographic analysis from the voicing onset (first glottal pulse) to the loss of audible signal and the decrease in the energy of higher formants (F2). The decrease of energy was visualized through wideband spectrograms where a lowering of F2 was visible while the oral cavity was enlarged because of tongue retraction (Binos et al, 2020).…”

“…The aim of this literature overview was to present recent findings on suprasegmental duration features in young CI recipients based on very early speech transitions called vocants, and to compare a recent study based on Greek language (Binos et al 2020) other studies exploring similar phenomena.…”

“…Vowel duration during babbling is crucially important for future speech and language development: shorter vocal duration is related to mature adult-like vocalizations (Kent, Forner, 1980). There is an extensive work related to midfront, low-front and central vowels of children with normal hearing (NH) (Fernald 2004, Katz, Cohn, Moore, 1996, Kitamura, Lam, 2009 during the babbling stage but there are only few reported studies focused on vocant prosodic features (quasivowels and full vowels) of infants with severe-toprofound hearing loss despite their clinical importance (Binos, Thodi, Vogazianos, Psillas, Constantinidis, 2020).…”

Vocants are precursors to speech and are facially neutral. The presence of these speechlike vocalizations was evident during the precursors to mature phonology called “protophones”. The prosodic feature of duration of the nuclei plays a crucial role in the shift of prelexical to mature speech, since speech intelligibility is closely related to the control of duration. The aim of this work is to determine whether cochlear implants (CIs) positively trigger language acquisition and the development of verbal skills. Recent literature findings are compared and discussed with the performance of two Greek congenitally hearing-impaired infants who were matched with three normal-hearing (NH) infants. This work highlighted an important weakness of the prosodic abilities of young infants with CIs.

Objective: The present case study aims to report on the consonant repertoire during the pre-linguistic and first linguistic stage of a Greek-Cypriot speaking child bilaterally implanted with multichannel Cochlear Implants (CIs). Background: Children with Hearing Loss (HL) produce canonical babble later, and consonantal inventories of HL children are smaller. However, the consonant repertoire of CI Greek-speaking children has not been examined thus far and research on types of consonantal errors during phonological acquisition is scant. Clinical Case: A pre-linguistically deaf child (CY, 7;0 years old) received the first CI at 7 months of age, but the external part of the device was fitted at 2;7 years. An investigation of the child’s speech at 7;0 years was conducted through auditory analysis. The child’s canonical utterances were transcribed in IPA and his consonants were classified into subcategories, depending on articulation place, articulation manner and resonance. Regarding place, alveolar consonants were the main category produced. As regards manner, closed consonants was the first category to appear, while in terms of voicing, voiceless consonants were recorded more often than voiced ones. The analysis also showed that consonants /t/, /s/ and /p/ were dominant in the child’s speech and revealed several phonological processes. Conclusion: The present case holds special interest as the child’s phonological system is still between the pre-linguistic/first linguistic stages due to the delayed CI mapping. The results agree in part with several studies in the literature, while specific phonological error patterns observed, remain to be verified in other CI Greek-speaking children.
