The present study was a preliminary investigation on the tone perception performance
of pre lingually hearing-impaired children with cochlear implant. Seventeen native
Cantonese-speaking participants were invited in this research. They have been using
the Nucleus multichannel cochlear implant with coding strategy of either SPEAK or
ACE. Errors from the tone discrimination and the tone identification tests were
examined and a tone confusion matrix was plotted. Results revealed that the correct
scores for both discrimination and identification tests were slightly above chance
levels, indicating that prelingually hearing-impaired children using cochlear implants
were able to benefit from SPEAK or ACE strategies for Cantonese tone perception,
though the benefit was small. Tonal error and confusion patterns were discussed and
some contributing possibilities were suggested. Relationships between tone perception

performance and other variables such as age at implantation, duration of implantation,
frequency of training and overall auditory performance were also examined. The
paper also discussed other possibilities that may contribute to tone confusion.
