N2 - In this report we describe the vowel identification ability of eight patients who scored above 70% correct on a test of spondee word identification. The stimuli were 12 synthetic vowels in “bVt” format. The vowels differed in the frequency of F1, F2, and F3. The mean identification accuracy was 60% correct. Front vowels and dipthongs, /3^/, and /u/ were relatively well identified. The vowels in “but,” “bought,” and “bout,” which were characterized by high F1 s and low F2s were not well identified. The results are consistent with a model of recognition in which FI is specified, with relatively good accuracy, by a rate code and in which extreme values of F2 are specified by a rate/place code.
