A guy's voice typically begins to change during puberty, which can start around ages 11 to 14 and may continue to develop until about age 18. The process involves the lengthening and thickening of the vocal cords, leading to a deeper voice. While significant changes can occur within a couple of years, individual development can vary widely based on genetics and other factors. Ultimately, the voice may continue to mature even into the early twenties.
