TABLE II.
Perceptual distance between CI subjects S43 and S47 and NH listeners' vowel identification confusion matrices for each vocoder condition. The smallest perceptual distance values, which signify the most similar confusion patterns, are between S43's confusion matrices and the vocoder conditions that manipulated the middle frequency regions.
