This study examines the acoustic features of vowels of four children who are 9 years old: two cerebral palsy (CP) and two normally developed. The voice samples from these children were collected using the picture-naming task and then analysed. Acoustic features like Formant frequencies (F1 & F2) and acoustic space of the vowels are examined. The study's findings indicated the following: 1. F1 is much developed in CP children as compared to F2; 2. the acoustic space area occupied by the vowels of the male CP child is more than the female child of the same age; 3. Further the acoustic space area of CP children is smaller than a typically developed children of the same age.
