The data for the study gave no indication that vocal pitch frequency of the fundamental was affected by the frequency of a stimulus tone that sounded in a speakers ear during reading. Clearly, however, both the intensity and pitch of voice were affected by the level of the tone that was heard. These effects, however, appeared not to be a function of the intensity of the tone but rather of its loudness. Moreover, they were differential. As the tones were increased from loudness level 10 to 65 through 11 points of measurement vocal intensity and frequency increased linearly. Responses to tones of higher loudness levels were not in keeping with these patterns. Both vocal pitch and intensity increased with greater rate per unit change of the loudness level of the stimulus tone at higher levels, and the acceleration rate was greater for vocal intensity than for frequency. The possibility is suggested that in the production of vocal intensity there is more control in the lower portion of the continuum from soft to loud than in the upper part of this range. Author
