![]() ![]() Vocal folds are used as sound sources in various species, but it is unknown how vocal fold morphologies are optimized for different acoustic objectives. Predicting Achievable Fundamental Frequency Ranges in Vocalization Across Species Finally, there was no correlation between subjects' success on standardized puretone pitch tests and ability to judge average pitch in the speaking voice. Both groups performed at chance level until differences in vocal fundamental frequency exceeded 20 Hz. Results indicated that trained clinicians were no better at judging average fundamental frequency than were untrained listeners. Finally, ability to perceive pitch differences in speaking voices was correlated with ability to judge puretone stimuli. We also attempted to determine the degree of difference in fundamental frequency necessary for accurate judgments. 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. Perception of the fundamental frequencies of children's voices by trained and untrained listeners. The role of speaking in too low pitch as causal for vocal symptoms and need for voice classification differentiation in vocal performance studies are discussed. Data analysis showed group differences in mean SFF, no differences in vocal range, higher mean SFF values for reading than speaking, and 58% ability to perceive speaking in low pitch. Subjects were assigned to a normal voice or impaired voice group based on ratings of perceptual tasks and survey results. Recorded signals were digitized prior to being analyzed for SFF using the Kay Computerized Speech Lab program. Vocal range and perceptual characteristics while singing with low intensity and high frequency were also assessed, and subjects completed a survey of vocal habits/symptoms. Nineteen trained soprano singers aged 18-30 years vocalized tasks designed to assess average speaking fundamental frequency (SFF) during spontaneous speaking and reading. Average speaking fundamental frequency in soprano singers with and without symptoms of vocal attrition. ![]()
