When developmental change is discontinuous, however, researchers may identify not only milestones of development, but related age periods often called stages. These stages are periods of time, often associated with known age ranges, during which a behavior or physical characteristic is qualitatively different from what it is at other ages.
Youth has a certain unique quality in a person's life; it is a bridge between childhood and adulthood.

During puberty, changes in the larynx typically result in a decrease in pitch in both males and females. On average, the male voice deepens by one octave while the female voice lowers by a few semitones. [7] The fundamental frequency (pitch) of an adult female typically falls between 165 and 255 Hz and an adult male between 85 and 180 Hz. [8]
