Dysphonia: what it is, causes, and how to recover your voice

Dysphonia is much more than just "being hoarse." When dysphonia appears and becomes persistent, it can affect communication, social life, work performance, and even self-esteem. 

Throughout this text you will understand why dysphonia should not be ignored, what signs require evaluation, and how appropriate intervention can restore a healthier, firmer, and more confident voice.

What is dysphonia?

Simply put, dysphonia is any alteration of the voice that prevents it from sounding "normal" to that person. It can be translated as hoarseness, A breathy, tense, or trembling voice; voice breaks; difficulty projecting or sustaining the voice; or a feeling of constant effort when speaking.

In practice, whenever the voice changes persistently in intensity, tone, timbre, or stability, we are dealing with dysphonia. These changes can be slight or very marked, temporary or prolonged.

Dysphonia is not a single disease, but rather a sign that something is not working properly at the level of:

• of the vocal folds

• of the larynx

• the coordination between breathing, phonation and resonance

• or even emotional and neurological factors

That is why dysphonia is a symptom that deserves to be evaluated by an otolaryngologist and, often, monitored in a specialist. Speech therapy, especially when it interferes with daily life.

Functional dysphonia and organic dysphonia: main types

To better understand dysphonia, it helps to divide the problem into broad groups. Clinically, dysphonia is often classified as:

• Functional dysphonia

  • The structure of the vocal folds is intact.

  • The problem lies primarily in how the voice is used: excessive effort, poor vocal technique, muscle tension, and harmful vocal habits.

  • It is common among teachers, singers, call center operators, and other voice professionals.

• Organic dysphonia

  • There is a structural alteration in the vocal folds or larynx.

  • It may be associated with nodules, polyps, cysts, Reinke's edema, vocal cord paralysis, benign or malignant tumors, chronic inflammation, among other causes.

• Neurological dysphonia

  • It results from alterations in the central or peripheral nervous system, such as vocal cord paralysis or spasmodic dysphonia.

• Psychogenic dysphonia

  • This occurs when dysphonia is strongly associated with emotional factors, stress, anxiety, or traumatic events.

In any of these cases, dysphonia is real, impacts quality of life, and can be addressed with appropriate intervention.

Most common causes of dysphonia in adults

Dysphonia in adults is common throughout life. Studies indicate that about 30 percent of people will experience hoarseness or significant dysphonia at some point.

Among the most frequent causes of dysphonia in adults are:

• Respiratory infections (colds, laryngitis, flu)

• Excessive use or abuse of vocals (speaking loudly, shouting, talking for many hours at a time)

• Poor vocal technique in voice professionals.

• Gastroesophageal or laryngopharyngeal reflux

• Smoking and exposure to irritants (smoke, chemicals, very dry air)

• Respiratory allergies

• Nodules, polyps, or cysts on the vocal cords.

• Vocal cord paralysis

• Hormonal changes (e.g., thyroid disorders)

• Benign or malignant tumors of the larynx

It's important to understand that persistent dysphonia is neither "normal" nor "a sign of aging." Whenever dysphonia lasts more than 2 to 3 weeks without an obvious cause such as a cold, it should be evaluated.

Dysphonia in children: when hoarseness is a warning sign

There is a very common idea that it is "normal" for a child to be hoarse. The evidence shows exactly the opposite: childhood dysphonia is a warning sign and should be taken seriously.

Studies indicate that dysphonia can affect between 6 and 23 percent of school-aged children, being more frequent in boys.

In children, dysphonia is often linked to:

• vocal abuse (shouting, constant noisy play)

• imitation of cartoon voices

• talking continuously in noisy environments (playground, gyms, sports)

• The presence of vocal fold nodules, which are one of the most frequent causes of childhood dysphonia.

Childhood dysphonia can coexist with other disorders, such as childhood apraxia of speech or childhood stuttering, who also require assessment and intervention in speech therapy.

Ignoring dysphonia in childhood risks the child growing up with a permanently altered voice, impacting their participation in the classroom, presentations, play, and social relationships.

Symptoms of dysphonia: how to recognize when your voice needs help.

Although everyone experiences dysphonia differently, there are signs that deserve special attention. If, over several days or weeks, you notice:

• persistent hoarseness

• voice that falters or "disappears" throughout the day

• difficulty in being heard in normal environments

• sensation of a foreign object in the throat

• pain, burning or tiredness when speaking

• need to make a great effort to speak

• feeling short of breath when speaking

• Constant use of throat clearing to "clean" the voice.

It is likely that you are dealing with dysphonia that requires evaluation.

Repeatedly clearing your throat, for example, often worsens dysphonia because it increases friction on the vocal cords.

How is dysphonia diagnosed?

The diagnosis of dysphonia is always clinical, based on the evaluation of several professionals:

1. Otorhinolaryngologist (ENT)

   • It directly examines the larynx and vocal folds, often using laryngoscopy or video stroboscopy.

   • Look for signs of injury, inflammation, paralysis, tumors, or other abnormalities.

2. Speech therapist

   • It assesses vocal quality (intensity, tone, timbre, stability), breathing, posture, resonance, and vocal habits.

   • It analyzes the impact of dysphonia on communication, work, and daily life.

3. Other professionals, if necessary.

   • Psychology, Internal medicine, gastroenterology, neurology, among others, when systemic or emotional causes are suspected.

Dysphonia is described today as a communication disorder that should be viewed from a specific perspective. biopsychosocial, That is, integrating body, mind, and life context.

Dysphonia treatment

The good news is that a large proportion of dysphonia cases improve significantly with appropriate intervention. Dysphonia treatment always depends on the cause, but it usually combines:

1. Medical treatment

In many cases of dysphonia, the first step is to treat the underlying cause:

• • medication for infections

  • treatment of gastroesophageal reflux

  • allergy control

  • eventual surgery to remove nodules, polyps, or other lesions when indicated.

  • Specific approaches in vocal fold paralysis or spasmodic dysphonia

Even when surgical intervention is necessary, dysphonia rarely resolves with surgery alone. Vocal rehabilitation with speech therapy is essential to consolidate results and prevent relapses.

2. Speech therapy in dysphonia

A Speech therapy It is one of the most evidence-based approaches in the rehabilitation of dysphonia, both in children and adults.

In dysphonia, speech therapy intervention may include:

• • Vocal education: understanding how the voice works and what is causing dysphonia.

  • Correction of harmful vocal habits (shouting, throat clearing, straining to speak, speaking in noisy environments without support).

  • Breathing exercises and respiratory support for the voice.

  • Relaxation techniques for the muscles of the neck, shoulders, and larynx.

  • Resonance exercises to make the voice more economical.

  • Effortless vocal projection training

  • Specific strategies for voice professionals

Many of these exercises are similar to those you find in the content of speech therapy exercises, but they must always be adapted by a speech therapist to the specific needs of each person.

Nowadays, it is also possible to do Online speech therapy, through video conference consultations, with results comparable to those of in-person intervention in many cases, according to the literature on telepractice in communication disorders.

If you are looking for convenience, you can use services from Online speech therapy, which allow for the continuation of dysphonia treatment from home, provided there are adequate technical conditions.

Vocal hygiene: habits that help recover from dysphonia.

Recovery from dysphonia doesn't depend solely on speech therapy sessions. Daily habits can significantly accelerate or delay the process. Some scientifically supported vocal hygiene strategies include:

• Proper hydration

  • Drink water throughout the day, avoiding large amounts at once.

  • Give preference to water and avoid drinks that are too sugary or excessively carbonated.

• Avoid smoking and secondhand smoke.

  • Tobacco is one of the greatest enemies of the voice and a risk factor for laryngeal pathology.

• Reduce throat clearing

  • Replace with small sips of water or dry swallows.

• Limit the use of voice during exertion.

  • Avoid competing with background noise (restaurants, bars, gyms).

  • Use amplification when necessary (teachers, trainers).

• Taking care of the environment

  • Avoid excessively dry air, dust, and irritants.

  • Maintaining good sleep quality also influences the voice.

• Pay attention to reflux.

  • Avoid eating very heavy meals at night.

  • Reduce consumption of highly acidic, fatty, or spicy foods if reflux has been diagnosed.

Vocal hygiene is an essential part of the intervention plan for dysphonia and remains important even after voice recovery, to prevent relapses.

Dysphonia and other communication disorders

Dysphonia can coexist with other communication disorders, and therefore, the assessment should be comprehensive. In adults with neurological lesions, for example, voice and language alterations may also occur, such as... aphasia, which affects verbal comprehension and production.

In children, in addition to dysphonia, speech, language, fluency, or phonological processing disorders may be present. 

When to seek help for dysphonia

Not all dysphonia requires urgent attention, but there are signs that indicate it's not worth delaying:

• dysphonia that lasts more than 2 to 3 weeks

• dysphonia associated with intense pain, difficulty swallowing or breathing

• dysphonia in long-term smokers

• dysphonia in voice professionals, even if "habitual"“

• dysphonia in children, especially if persistent or associated with visible vocal strain.

• dysphonia accompanied by weight loss, blood in the saliva, or a persistent foreign body sensation.

In these cases, a professional should be consulted. otorhinolaryngologist and a speech therapy assessment has been scheduled.
