Incorrect productions of / / were compared to correct productions of /s/ and / / in two apraxia/aphasic subjects. Peak spectral frequencies were extracted from power spectrums of monosyllabic words. In addition, a perceptual task was completed by requiring two listeners to categorize recorded productions. For one subject, results revealed no significant differences among peak spectral frequencies for each sound category. However, perceptually these sounds were judged to be different. For the second subject, acoustic and perceptual findings corresponded with sounds being differentiated.
