The fundamental frequency (f0) characteristics of 28 esophageal speakers measured on a wave-by-wave basis were compared with the f0 characteristics of these same speakers measured on an averaging basis. Fundamental frequency mean, standard deviation, and mid-90% range values measured on an averaging basis correlate strongly with those obtained on a wave-by-wave basis. The mean fundamental frequency for esophageal speakers did differ significantly (p< 0.001) as a function of measurement technique. This difference was small (0.75 semitones) and does not account for the 20- to 30-Hz difference in average fundamental frequency of esophageal speech reported by various investigators. The implications of these findings are discussed.
