The acoustic spectrum of the nasal consonant [m] was analyzed from utterances of subjects as they produced it (1) in monosyllables, (2) in the reading of a paragraph, and (3) in attempts to disguise their voices while speaking a sentence. Findings indicate that although there is considerable intra-subject variability in the overall spectrum of the [m] consonant, the first formant remains remarkably constant. LPC analysis was employed in extracting acoustic characteristics. The results of this study have implications for speaker identification.
