Abstract: Objective To revise the assessment of consonant vowel and tone recognition for cochlear implanted children. Methods 300 normal hearing children aged 2~6 years old were assessed with word lists for consonant and vowel recognition, and analysed with equivalency analysis. Results The incidence of consonant vowel and tone recognition was less than 90% in children aged 2~3 years old, but more than 90% in those aged 3 or more. Conclusion The assessment of consonant vowel and tone recognition for cochlear implanted children aged of 3 and above has been modified, and the assessment for those aged 2~3 years old has been developed.

Key words: cochlear implantation, hearing rehabilitation, consonant recognition, vowel recognition, tone recognition
