Abstract—Speech disability is one of the widely encountered disabilities among the disabled children. In this study, adaptive signal processing is used to tune the speech signal of disabled children into curve fitted speech signal of normal child by implementing feedback mechanism technique. The curve fitted speech signal constants of normal child is compared to tuned constant values of disabled child and the deviation is calculated using correlation technique. The amount of deviation represents the severity of speech disability in children compared to a normal child. The speech therapy can be given to the speech disabled children to improve the utterance capability.
