Abstract
Voice breaks occur suddenly within a particular wave rather than the gradual changes occurring in inflectional variations in language. When subjects whose voices are "breaking" during puberty are compared with subjects in the literature who have organic anomalies certain differences appear. Normal subjects break downward nearly an octave, or a pitch approx. one-half that of the original level, while organic cases tend to drop one-third of the original fundamental. Pathological subjects show considerable variation * of the fundamental both before and after the break. Pathological cases seem to show a typical breaking frequency for each individual. In contrast, normal subjects displayed a more closely knit vocal behavior.
