We included four variables: 1) the trends of canonical babbling ratio; 2) their consonant repertoires when reaching the canonical babbling stage; 3) the proportions by which reduplicated and variegated babbling take respectively in multisyllabic babbling, and 4) the complexity of their phonetic variations in canonical babbling. Recordings were collected three times every month for 12 to 14 months. Results showed that the onset of canonical babbling stage occurred 2 to 5 months post-implantation, and the consonant repertoire was about 4 to 12. Bilabials and labiodentals were the most commonly used places of articulation, and the majority of manners of articulation were nasals and stops. There was only one infant whose variegated babbling ratio was first noticeably higher than that of reduplicated babbling between 12-13 months of hearing age. The proportion of variations involved both consonant and vowel were 11.11% to 30%. In sum, we found two types of learning strategies used by the four subjects - ‘phonetic-oriented’ and ‘semantic-oriented’. Our findings aim to provide insights for clinical practitioners to focus more on the development during the prelinguistic period, as part of their evaluation routine to monitor subjects’ language progress post-implantation and adjusting their intervention goals if needed.語音複雜度子音廣度人工電子耳嬰幼兒典型喃語前語言期發展phonetic complexityconsonant repertoireinfants with cochlear implantscanonical babblingprelinguistic periodthesis
