Does your voice deepen after 18?

Men’s voices often deepen up to an octave, while women’s voices usually move about three tones lower. After puberty and well into older adulthood, some people’s voices may change, but not everyone’s. Men’s voices tend to go up in pitch. Women’s voices tend to go down.

At what age does your singing voice peak?

Singers’ voices mature anywhere from their 20s to the early 40s, and, in general, voices that are deeper and heavier in tone take longer to develop fully. Coloraturas, or sopranos with light voices, typically reach their peaks earliest, in the mid-20s.
