The human voice is one of our primary tools for communication. For children, it’s not just a means to express their needs but also a way to learn and interact with the world. As a parent, understanding how your child’s voice works and how to care for it is essential. In this article, we will help you understand the intricacies of your child’s voice production and care.

Anatomy and Physiology of Voice Production

The voice is produced when air from the lungs passes through the voice box or larynx, causing the vocal cords (or vocal folds) to vibrate. This vibration creates sound waves, which are then modified by the throat, mouth, pharynx, and nasal passages to produce speech.

Key Components:

• Lungs: Source of airflow.
• Trachea: The windpipe that carries air from the lungs to the larynx.
• Larynx: Contains the vocal cords and regulates the pitch of the voice.
• Vocal Cords: Two muscle-controlled band-like structures that vibrate to produce sound/phonate.
• Resonators: The mouth, palate, pharynx, and nasal passages which shape the sound.

Development of Voice Production in Children

Children’s voices evolve as they grow:

• Infancy: Babies’ vocal cords are much shorter than adults, which is why their voices are higher-pitched.
• Toddlerhood: As children learn to speak, they experiment with different sounds, loudness levels, and pitches, refining voice control.
• Adolescence: With puberty, the voice undergoes significant changes. Boys typically experience a voice change as their vocal cords thicken and enlarge.

Voice Disorders in Children

Children can experience a range of voice disorders. Some common ones include:

• Nodules: Small, non-cancerous growths on the vocal cords, often due to excessive shouting or coughing.
• Polyps: Similar to nodules but softer and often caused by vocal abuse or injury.
• Vocal Cord Weakness or Paralysis: When one or both vocal cords cannot move well or at all, leading to voice changes, and feeding and/or breathing difficulties.
• Chronic Laryngitis: Inflammation of the vocal cords causing hoarseness, often due to infections, allergies, or acid reflux.
• Hyper or hypo-nasality: Voice quality that is altered by too much or too little air flow through the nasal cavity.

Vocal Hygiene: Protecting Your Child’s Voice

Vocal hygiene refers to practices that help maintain a healthy voice. Parents can support this by:

• Helping Child to Be Aware of How to Protect Their Voice: Model and teach your child about using their “inside voice” and how and why it is important to avoid hurting their voice by screaming, shouting, and whispering.
• Hydration: Ensure your child drinks enough water to keep the vocal cords lubricated.
• Limit Throat-Clearing: Excessive throat clearing can strain the vocal cords.
• Humidify: In dry environments, use a humidifier to keep mucous membranes moist.

Identifying Voice Problems & Seeking Help

If your child has persistent hoarseness, unusual voice quality, throat pain, difficulty swallowing, or any voice change that concerns you, it’s essential to consult their pediatrician and if indicated, a pediatric Ear Nose and Throat specialist.

Role of a Pediatric Ear Nose and Throat Specialist

A Pediatric Ear, Nose, and Throat (ENT) specialist or Otolaryngologist, diagnoses and treats children’s voice disorders. They can assess the vocal cords, recommend speech-language therapy and other interventions, prescribe medication, and perform surgeries if indicated.

Role of a Speech-Language Pathologist in Childhood Voice Disorders

Speech-Language Pathologists (SLPs), play a pivotal role in diagnosing, treating, and preventing voice disorders in children. Their expertise extends beyond speech issues and includes a deep understanding of voice production.

Key Responsibilities of SLPs in Voice Care:

• Evaluation: SLPs conduct comprehensive voice assessments to identify the nature and extent of voice disorders. They use specialized tools and techniques.
• Voice Therapy: For many children with voice disorders, voice therapy is the first line of treatment. SLPs design tailored therapy intervention to address specific voice issues, teaching children exercises and techniques to improve vocal function.
• Education: SLPs educate children, their families, and caregivers about voice care. They offer guidance on vocal hygiene, voice conservation strategies, and ways to avoid behaviors that may harm the voice.
• Collaboration: In cases where medical or surgical intervention is needed, SLPs collaborate closely with pediatricians, ENT specialists, and other healthcare professionals to ensure comprehensive care. They often play a role in post-surgical rehabilitation, helping children regain optimal voice function.

FAQs

1. How do voices change during puberty?
   • During puberty, hormonal changes cause the vocal cords to grow. Boys usually experience a more noticeable drop in pitch than girls.
2. Can voice disorders be prevented?
   • While not all can be prevented, many result from vocal abuse. Educating children about using their voice healthily can prevent some disorders.
3. How long should I wait before consulting a doctor about my child’s hoarse voice?
   • Always consult your child’s physician for these kinds or recommendations.
4. What’s the difference between voice therapy and surgery for voice disorders?
   • Voice therapy teaches techniques to improve vocal function, while surgery is a direct intervention to treat structural issues.
5. Can allergies affect my child’s voice?
   • Yes, allergies can cause inflammation of the vocal cords or lead to chronic irritation and/or coughing, affecting voice quality.
