A short-term longitudinal study of vocal development in young children with simultaneous bilateral cochlear implants

Although children with early-identified hearing loss and simultaneous bilateral CIs make significant progress in vocal development, their vocal milestones remain delayed compared to those of their peers with TH. These children do not fully catch up in vocal development within 1 to 2 years of bilateral CI use. These findings highlight the need for targeted support and early intervention for children with CIs and their parents.
