For most people, the voice change that happens during puberty can cause a temporary dip in singing ability. However, there is no definitive age at which a person’s singing voice is at its best, as this can vary greatly depending on the individual’s natural talent, training, and dedication to practicing singing. Some people may reach their peak singing voice in their teens or twenties, while others may not do so until their thirties or forties. It’s also important to note that the idea of a “better” voice is subjective and can be influenced by cultural and personal preferences.
