Speech perception skills were assessed using phonetically balanced Hindi word list before implantation and at specified post-implant switch-on time periods for upto 2 years. The scores increased significantly in all five groups from pre- to post- CI in every follow-up. Positive effect of time was seen with better results in those implanted at younger age.
