TL;DR: HiRes 120 did not provide significantly improved lexical tone recognition compared to HiRes, at least throughout the length of the study (up to 6 mo); there were large individual differences in lexicaltone recognition among the prelingually deafened, native Mandarin-speaking children with cochlear implants using either HiRes or HiRes 120.

TL;DR: There is a remarkable deficit in tone production in a majority of native tone language speaking, prelingually deaf children who have received cochlear implants and the age at implantation appears to have a negative effect on tone production, therefore, early implantation might be beneficial totone production in preling sexually deaf children whose native language is a tone language.

TL;DR: In prelingually deaf children with cochlear implants, tone perception and production performance are highly correlated, consistent with the hypothesis that tone perception is the prerequisite for good tone production.

TL;DR: Children with cochlear implants showed significantly poorer performance in the pitch-based assessments than the normal-hearing children and no significant differences were seen between the two groups in the rhythm-based measure.

TL;DR: A potential speech development deficit was documented in prelingually deafened children with CIs whose native language is a tone language, which can be attributed to the paucity of pitch information delivered via the current CI stimulation.
