Early speech perception in Mandarin-speaking children at one-year post cochlear implantation.
Implant early and flood the child with native Mandarin to let natural reinforcement build speech perception.
01Research in Context
What this study did
Chen et al. (2016) followed Mandarin-speaking babies who had just received cochlear implants. They tracked how well the babies could tell speech sounds apart during the first year of implant use.
The team tested the same children over time. They wanted to see who improved fastest and why.
What they found
Children implanted before their first birthday made the biggest jumps in speech perception. Kids who still had some hearing before surgery also moved ahead faster.
Steady exposure to Mandarin at home and school kept the gains coming.
How this fits with other research
Schlinger (2023) says babies learn speech through automatic reinforcement—pleasant sound of their own voice makes them babble more. Yuan’s data line up: the sooner the implant gives clear sound, the sooner this natural loop can start.
Wilson et al. (1973) used tokens and a buzzer to speed up reading in hard-of-hearing grade-schoolers. Their payoff was immediate and artificial. Yuan’s infants learned without prizes; simply hearing their native language was reward enough.
Vukovic et al. (2010) found Serbian preschoolers with language impairment also move slower on motor tasks. Yuan’s babies show the opposite pattern: when hearing is fixed early, language keeps pace with typical movers.
Why it matters
If you work with infants who are deaf or hard-of-hearing, push for implant activation before 12 months. Keep parent coaching in the home language—no need for fancy reinforcers. Track speech-discrimination probes each quarter; they tell you if the device and the brain are in sync.

03Original abstract
PURPOSE: The aim in this study was to examine early speech perception outcomes in Mandarin-speaking children during the first year of cochlear implant (CI) use. METHOD: A hierarchical early speech perception battery was administered to 80 children before and 3, 6, and 12 months after implantation. Demographic information was obtained to evaluate its relationship with these outcomes. RESULTS: Regardless of dialect exposure and whether a hearing aid was trialed before implantation, implant recipients were able to attain similar pre-lingual auditory skills after 12 months of CI use. Children speaking Mandarin developed early Mandarin speech perception faster than those with greater exposure to other Chinese dialects. In addition, children with better pre-implant hearing levels and younger age at implantation attained significantly better speech perception scores after 12 months of CI use. Better pre-implant hearing levels and higher maternal education level were also associated with a significantly steeper growth in early speech perception ability. CONCLUSIONS: Mandarin-speaking children with CIs are able to attain early speech perception results comparable to those of their English-speaking counterparts. In addition, consistent single language input via CI probably enhances early speech perception development at least during the first-year of CI use.
