Puberphonia / Mutational Falsetto / Voice Break

Home » Voice Disorders » Puberphonia Treatment Bangkok 

The human voice naturally deepens during puberty as the vocal folds grow and thicken. In some individuals—particularly males—this transition may not occur properly, leading to a condition known as Puberphonia or Mutational Falsetto. The result is a persistently high-pitched, childlike voice despite normal physical development.

At Yoskarn Clinic in Bangkok, Dr. Somyot Kunjak and his highly experienced team, with over 40 years in voice and ENT surgery, provide specialized diagnosis and treatment for this condition, helping patients achieve a natural, confident voice that matches their identity.

Understanding Puberphonia

Puberphonia is not caused by structural abnormalities but rather by muscle tension and learned vocal behavior. The individual continues to use a prepubescent vocal pattern, often reinforced by psychological or emotional factors such as anxiety, self-consciousness, or voice identity issues.

Typical symptoms include:

• Abnormally high-pitched voice after puberty

• Weak or breathy voice quality

• Voice fatigue during speaking

• Inability to project or control pitch

Without treatment, the condition may persist into adulthood and affect confidence, communication, and social interaction.

Diagnosis at Yoskarn Clinic

At Yoskarn Clinic, we perform a detailed voice evaluation that includes:

• Stroboscopic examination to assess vocal fold vibration and tension

• Voice acoustics and pitch analysis using advanced software

• Laryngeal function testing to identify muscle imbalance

This comprehensive assessment allows our specialists to distinguish puberphonia from other voice disorders and determine the best approach for treatment.

Treatment Options

1. Voice Therapy
   Most cases of puberphonia can be corrected with professional voice therapy. Our speech-language pathologists use behavioral voice exercises to retrain proper vocal fold vibration and strengthen lower pitch control.

2. Surgical Intervention (If Required)
   For resistant cases, Dr. Somyot Kunjak performs laryngeal framework adjustment or endoscopic voice correction to optimize vocal fold tension and resonance—procedures that are safe, minimally invasive, and highly effective.

3. Psychological Counseling & Confidence Training
   Because voice identity is deeply connected to self-image, our holistic approach includes counseling support to help patients adapt to their new, mature voice.
