title: Perception of the fundamental frequencies of children's voices by trained and untrained listeners.
abstract: This study was designed to determine if trained voice clinicians were better than untrained listeners in judging differences in the fundamental frequencies of children's voices. We also attempted to determine the degree of difference in fundamental frequency necessary for accurate judgments. Finally, ability to perceive pitch differences in speaking voices was correlated with ability to judge puretone stimuli. Results indicated that trained clinicians were no better at judging average fundamental frequency than were untrained listeners. Both groups performed at chance level until differences in vocal fundamental frequency exceeded 20 Hz. Finally, there was no correlation between subjects' success on standardized puretone pitch tests and ability to judge average pitch in the speaking voice.
