This study utilized acoustic analysis to explore changes in voice and speech for five prelingually deaf males pre- and post-implantation over 6 months. The following measurements were obtained: fundamental frequency (F0), jitter, shimmer, noise-to-harmonic ratio, voice turbulence index, soft phonation index, amplitude- and F 0-variation, F0-range, speech rate, nasalance, and vowel production. Vowel production was measured by determining the first formant and second formant (F2) of vowels in various contexts, and magnitude and rate of F2-variation. Perceptual measurements of pitch, pitch-variability, loudness-variability, speech rate, and intonation were obtained for comparison. Results showed patterns of change for some of the parameters with considerable variation across the subjects, the majority of changes occurring from pre- to 2-weeks post-implantation. Perceptual measures showed strong and moderately strong correlations for pitch variation and F0-variability, speech rate and syllables per second, prosody and F0-variability, and prosody and syllables per second.
