The age at which a person’s voice fully develops and reaches maturity can vary substantially between individuals. However, there are some general patterns and timelines for vocal development that apply to most people.
Quick Answers
– The full maturation of the vocal cords and voice box typically occurs between ages 13-15 in boys and 12-14 in girls as part of puberty.
– However, the voice can continue to change and develop into the late teens and early 20s as the larynx grows.
– Voices are considered fully developed and mature by the late teens for females and early 20s for males on average.
– Many factors like genetics, hormones, and vocal use can affect the pace and progression of vocal development.
– Proper vocal training and technique can maximize vocal potential regardless of age.
Vocal Development in Childhood
Vocal development begins early in life as infants begin to make sounds and babble. As the larynx grows, the vocal range expands and children can produce a wider variety of sounds and pitches. By age 2-3, most children have a vocabulary of several hundred words and can modulate their voice for speech.
Between ages 3-8, the vocal cords elongate and thicken which lowers the pitch of the voice. However, large jumps in vocal range still occur with changes in emotion and vocal effort. Pre-adolescent voices lack the muscular coordination and control of mature voices.
Changes During Puberty
The most significant changes happen to the voice during puberty, as rising levels of testosterone in boys and estrogen in girls spur growth of the larynx. In boys, the larynx grows prominently resulting in an obvious deepening of the voice.
Girls experience less dramatic vocal changes than boys during puberty. However, their vocal cords also thicken and they develop a more mature sounding voice. Below are some general timelines for vocal changes during puberty:
- Girls: Voice deepens between ages 12-14
- Boys: Voice begins deepening around age 13 and drops dramatically by age 15
These vocal changes occur as the laryngeal prominence (“Adam’s apple”) grows more prominent. The larynx and vocal cord growth is typically completed earlier in girls compared to boys.
Continued Vocal Maturation
Although puberty accounts for significant vocal change, the voice can continue developing and maturing into the late teens and early 20s. For males particularly, the larynx continues growing and vocal range expands into adulthood.
Other changes that may occur include:
- Stabilization of vocal pitch and timbre
- Increased vocal power and projection
- Expanded vocal range and ability to modulate pitch
- Improved vocal stamina and reduced vocal fatigue
- Better breath support and resonance
Vocal cords and the muscles around the larynx finish developing which provides greater control over the voice. By the early 20s, most voices are considered fully mature in both males and females.
Maximizing Vocal Potential
While vocal anatomy is still maturing, steps can be taken to maximize your vocal potential regardless of age:
- Proper hydration to keep vocal cords lubricated
- Good breath support by engaging the diaphragm
- Avoiding overuse or straining of the voice
- Practicing healthy vocal technique when singing
- Working with vocal coaches to develop skills
- Allowing time for vocal rest and recovery
With care and training, people can learn to use their voice effectively at any stage of development. Even after maturation, vocal improvement is possible with dedication to the craft.
Genetic and Health Factors
Genetic and health factors can impact the progression of vocal development in some individuals. For example:
- Hormonal imbalances may accelerate or delay pubertal changes.
- Differences in larynx size and shape affect pitch.
- Medical conditions like acid reflux can irritate the vocal cords.
- Allergies and sinus issues make breath support harder.
Consulting a doctor is recommended if vocal issues arise to check for any underlying health conditions. With proper treatment, vocal development typically resumes its normal track.
Role of Sex Hormones
The surge in sex hormones during puberty drives growth of the larynx and maturation of the vocal cords. Testosterone causes more dramatic enlargement in boys, while estrogen impacts vocal change in girls more subtly. Hormones affect both the structure and function of voice production anatomy.
However, hormone levels vary greatly among individuals based on factors like:
- Genetics
- Stress
- General health
- Body composition
Those with lower hormone levels may experience slower or less significant vocal changes during puberty. Imbalances in key hormones like testosterone, estrogen, and growth hormone can impact vocal development.
Other Hormonal Factors
The thyroid gland also influences voice maturation. Thyroid hormones directly regulate growth and metabolism of the larynx. Insufficient levels can impair vocal development in children and adolescents. Voice problems may even be the first sign of an undiagnosed thyroid disorder.
Cortisol and other stress hormones can also temporary alter voice pitch and control. Maintaining low stress levels allows vocal mechanisms to develop properly.
Developmental Differences Between Genders
As mentioned, vocal development differs significantly between males and females due to distinctions in larynx size and hormone levels. Here is a summary of key gender differences:
- Males experience a more dramatic voice change during puberty, with vocal pitch dropping by about an octave.
- Growth of the larynx and laryngeal prominence is much more pronounced in males.
- Testosterone stimulates greater vocal cord thickness and lengthening in males.
- Females complete vocal maturation 1-2 years earlier than males on average.
- Adult male voices end up around an octave lower than female voices.
However, there is overlap between genders, with some females developing lower voices and some males experiencing minimal dropping during puberty.
Transgender Voice Development
For transgender individuals undergoing hormone therapy, the vocal changes parallel those of their affirmed gender. For example:
- Transgender males experience significant voice deepening from testosterone.
- Transgender females may see moderate voice changes from estrogen.
Many transgender people also work with speech therapists or vocal coaches to further develop their vocal identity.
Vocal Changes Later in Life
After adolescence, the vocal structures are fully developed. But natural changes can still occur with aging:
- Voices may deepen slightly between ages 20-45.
- Pitch range starts decreasing after age 45.
- Loss of elasticity can cause voice hoarseness.
- More vocal effort required to project and modulate voice.
Vocal issues become more common as muscle tone declines. Proper hydration, limited vocal strain, and vocal exercises help maintain a healthy voice with age.
How Long to Develop Strong Singing Voice?
Developing a strong singing voice requires years of training, regardless of innate talent. Steps that help build vocal power include:
- Daily practice with vocal warmups/exercises.
- Learning proper breathing technique.
- Studying music theory.
- Taking lessons to perfect technique.
- Practicing challenging vocals.
- Performing regularly for experience.
With dedication, singers can strengthen their voices at any age. But it often takes a minimum of 5-10 years to master vocal control and develop an impressive range.
Professional Singers
Even professionally trained singers in choirs, theater, and music take years to perfect their craft. Key milestones include:
- 5+ years of vocal lessons to develop technique.
- 10,000+ hours of solo rehearsal time.
- Bachelor’s or Master’s degree in music/voice.
- Performing professionally for 3-5+ years.
Significant investment over 10-15 years is typical to becoming an expert vocalist. Proper vocal health habits are also critical.
Speech Therapy for Voice
For vocal issues not resolved after puberty, speech therapy provides targeted treatment. Goals of voice therapy include:
- Expanding vocal range and strength.
- Correcting hoarse or breathy voice.
- Treating vocal strain.
- Improving speech clarity.
- Regaining control after injury/surgery.
After identifying any physiological issues, a customized therapy plan is developed. Young singers can also benefit from working with speech therapists.
Voice Feminization Therapy
This type of therapy helps transgender women develop more feminine vocal qualities:
- Raising overall vocal pitch.
- Adjusting resonance and inflection.
- Reducing vocal effort.
- Expanding pitch range.
- Adopting language patterns.
Over 6-24 months of regular sessions, significant voice changes are possible.
Voice Masculinization Therapy
For transgender males, therapy aims to lower pitch and develop masculine speech patterns:
- Lowering vocal pitch.
- Increasing vocal power/projection.
- Adjusting inflection and tone.
- Expanding low-pitch range.
- Using speech patterns/filler words.
Testosterone helps drop pitch, while therapy aids adaptation and control.
Vocal Surgery Options
For those still dissatisfied with their voice after maturity, surgical interventions are options. These include:
- Pitch surgery – Manipulates size of vocal cords to raise/lower pitch.
- Glottoplasty – Reshapes vocal cords for desired tone.
- Cricothyroid approximation – Elevates vocal pitch in males.
- Vocal cord injection – Bulks up cords for more power.
Risks include vocal scarring, loss of range, and voice fatigue. Results may be subtle and multiple procedures needed. Many prefer voice therapy first.
Voice Feminization Surgery
Surgical options specifically for transgender women include:
- Reducing size of vocal cords.
- Shaving down the Adam’s apple.
- Thinning/shortening the vocal cords.
- Moving the voice box higher in the throat.
In combination with therapy, surgery can help raise vocal pitch and produce a more feminine voice.
Vocal Damage from Overuse
Before full maturation, adolescents need to be careful not to overexert their developing voice. Activities to moderate include:
- Excessive yelling/shouting.
- Frequent throat clearing.
- Hours of unsustainable singing.
- Very low/high pitches.
- Using an unnatural voice.
With overuse, young singers can develop vocal nodules or cysts from trauma to the cords. Rest and proper technique are key.
Preventing Vocal Injuries
To avoid damage while the voice is still developing:
- Stay hydrated to keep vocal cords lubricated.
- Avoid yelling/screaming unless trained.
- Resist the urge to talk/sing constantly.
- Stop using voice if pain or fatigue sets in.
- Learn proper breathing technique.
Teens face the temptation to push their voices. But moderation now prevents long-term damage.
Second Puberty and Vocal Changes
Some males experience a “second puberty” involving another series of voice changes in early adulthood thanks to shifting hormone levels.
Possible changes include:
- Voice slightly lowering in pitch.
- Sounding more resonant and “mature”.
- Gaining greater control over pitch.
- Increased ability to modulate voice.
- Expanded vocal range overall.
However, the difference is usually quite subtle compared to changes during the initial puberty years.
Causes
Second puberty vocal changes are linked to rising testosterone combined with final larynx growth. Possible contributing factors include:
- Natural testosterone boosts in early 20s.
- Increased muscle mass and circulation.
- Lifestyle changes like less sleep.
- Final adult height being reached.
- Stabilizing hormonal levels.
The voice reaching its masculine potential aligns with other body changes.
| Age Range | Milestones |
|---|---|
| Newborns | Babbling and crying |
| 6 months – 3 years | First words and simple sentences |
| 3 – 8 years | Expanded vocabulary, pitch varies greatly |
| 8-13 years (girls) | Prepubertal vocal growth |
| 12-16 years (boys) | Voice cracking as pitch lowers |
| 13-17 years (girls) | Voice deepening during puberty |
| 15-22 years (boys) | Completion of voice change |
| Early 20s | Voices mature and stabilize |
| 40s and up | Slight natural lowering of pitch |
Conclusion
In summary, the age at which the voice fully matures differs between genders with females finishing development 1-2 years earlier than males on average. The dramatic vocal changes initiated during puberty continue progressing through the late teens and early 20s in most individuals. With focused training and care, people can maximize the potential of their voice at any stage of life.
