Summary

This study tests whether a small recording device called LENA can help speech therapists guide parents to improve their child's language environment. Thirty children with profound congenital deafness who received a cochlear implant before 18 months old will wear the recorder at home for two 10-hour sessions, six months apart. The goal is to see if feedback from the recordings increases conversation turns and vocabulary.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
LENA (Language ENvironment Analysis) tool and speech therapy feedback
What this could lead to
If successful, this could show that using LENA recordings helps parents and therapists boost language development in young children with cochlear implants.
What could go wrong
This is a small, early-stage study with only 30 children. It measures changes in conversation turns and vocabulary, not long-term outcomes. Results may not apply to all families.
