Abstract
Selected characteristics were compared in the speech of five tracheoesophageal, five esophageal, and 15 normal laryngeal adult speakers. Tape-recorded speech samples were measured for durational features with a stopwatch. Frequency features were analyzed with a Visi-Pitch/Apple IIE computer interface with statistical subroutines. Tracheoesophageal speech proved comparable to normal speech in maximum phonation time, speech rate, pitch pertubation (jitter), average fundamental frequency, and fundamental frequency range, but less efficient than normal speech in phrase grouping. Tracheoesophageal speech was superior to esophageal speech in maximum phonation time, speech rate, and phrase grouping, but not significantly different in pitch perturbation, average fundamental frequency, and fundamental frequency range. Explanations and clinical implications of these findings are discussed.
