What Are Voice Disorders? 7 Types You Need to Know

Your voice is something you rely on every single day. So when it starts to sound different, feels strained, or disappears without warning, it is hard to ignore.

Voice disorders are more common than most people realize, and the good news is that most are very treatable when caught early. 

What Are Voice Disorders?

A voice disorder is any condition that affects how your voice sounds, feels, or functions. Your voice is produced when air from your lungs passes through your larynx, also called the voice box. 

Inside the larynx, your vocal cords vibrate together to create sound. When something interferes with that process, a voice disorder can develop.

Voice disorders can affect the pitch, volume, or quality of your voice. Some cause hoarseness or raspiness. Others may cause your voice to sound strained, breathy, or weak. In some cases, the voice may cut in and out or disappear entirely.

What are the Common Symptoms of Voice Disorders?

Voice disorders do not all look the same. The symptoms can vary depending on the type and cause. However, there are some common signs that something may be wrong with your voice.

Common dysphonia symptoms include:

• Hoarseness or a raspy quality to your voice

• A voice that sounds breathy or weak

• Strained or tight vocal quality, as if speaking takes extra effort

• Voice that cracks, breaks, or cuts out mid-sentence

• Changes in pitch that feel out of your control

• Vocal fatigue, especially after talking for short periods

• Complete loss of voice

• Throat pain or discomfort when speaking

It is normal for your voice to change occasionally due to a cold or heavy voice use. But if you notice any of these symptoms lasting more than two to three weeks, it is worth getting checked by a laryngologist. 

What Can Cause Voice Disorders?

Voice disorders can have many different causes. In some cases, the cause is structural or neurological. Some voice disorders even have psychological roots.

Common causes include:

• Overuse or misuse of the voice, such as yelling, talking loudly for long periods, or singing without proper technique

• Viral or bacterial infections that cause inflammation in the larynx

• Acid reflux, which can irritate and damage the vocal cords over time

• Neurological conditions that affect the nerves controlling the vocal cords

• Benign growths on the vocal cords, such as nodules, polyps, or cysts

• Psychological stress or emotional trauma

• Breathing in smoke, chemicals, or other irritants

• Surgery or injury to the neck or chest that damages nearby nerves

The 7 Common Types of Voice Disorders

1. Laryngitis

Laryngitis is one of the most well-known voice disorders. It happens when the larynx becomes inflamed and swollen, making it harder for your vocal cords to vibrate normally. Most people with laryngitis notice that their voice becomes hoarse, weak, or disappears altogether.

There are two types of laryngitis: acute and chronic. Acute laryngitis typically develops quickly and is often caused by a viral infection, such as the common cold. Chronic laryngitis lasts longer and can be caused by acid reflux, long-term voice overuse, or exposure to irritants like smoke.

What it feels like: Your voice may sound scratchy, low, or completely gone. You may also feel a tickling or raw sensation in your throat.

When to seek care: Most cases of acute laryngitis clear up on their own within a week or two. If your hoarseness lasts longer than three weeks, see an ENT doctor to rule out something more serious.

2. Vocal Cord Nodules and Polyps

Vocal cord nodules and polyps are both benign, meaning non-cancerous, growths that develop on the vocal cords. While they are similar, they are not exactly the same.

Nodules are like calluses. They tend to form in pairs and are caused by repeated friction from overuse of the voice. Polyps are more like blisters and are often larger. They can form on one or both vocal cords.

Both conditions are common in people who use their voice heavily, such as teachers, coaches, singers, and public speakers. Strained vocal cords from yelling, talking loudly, or improper vocal technique are major contributing factors.

What it feels like: You may notice hoarseness, a rough or breathy voice, vocal fatigue, or a sensation that something is stuck in your throat.

What helps: Treatment options include voice therapy, medication, and in some cases, surgical removal of the growth. Voice therapy teaches you how to use your voice more efficiently and reduce the habits that led to the problem in the first place.

3. Vocal Cord Paralysis

Vocal cord paralysis occurs when one or both vocal cords cannot move properly. This happens when the nerves that control the vocal cords are damaged or not working as they should. It can affect your ability to speak, swallow, and even breathe.

When only one cord is affected, unilateral paralysis, your voice may sound weak, breathy, or difficult to project. When both cords are affected, bilateral paralysis, breathing difficulties become the bigger concern. Unilateral paralysis is the more common of the two.

Possible causes include nerve damage from surgery on the neck or chest, a viral infection, a tumor pressing on a nerve, or neurological conditions. In some cases, no clear cause is found.

What it feels like: Your voice may be soft, airy, or strained. You may also notice that you run out of breath quickly while speaking, or that you have difficulty swallowing without choking.

What helps: Options include voice therapy, injections to bulk up the paralyzed cord, and surgery. Many people see meaningful improvement with the right treatment plan.

4. Spasmodic Dysphonia

Spasmodic dysphonia is a neurological condition that causes uncontrolled spasms in the muscles of the larynx. These spasms interfere with the movement of the vocal cords and disrupt the voice in ways that can be difficult to predict.

There are two main types. Adductor spasmodic dysphonia is the more common form and causes the vocal cords to squeeze together too tightly. This results in a strained, strangled, or choppy voice. 

Abductor spasmodic dysphonia causes the vocal cords to open too widely, resulting in a breathy or whispery voice that may cut in and out.

Spasmodic dysphonia is a form of vocal dysphonia that can be difficult to diagnose because it may be mistaken for other voice problems or even anxiety. The exact cause is not fully understood, but it is believed to involve abnormal signals in the part of the brain that controls movement.

What it feels like: Talking can feel like a struggle. Words may come out broken or strained. Some people find that the spasms are worse during certain activities like talking on the phone or in noisy environments.

What helps: Botox injections into the vocal cord muscles are currently the most effective treatment. They help relax the spasms and can restore more normal voice function for several months at a time. Voice therapy can also be helpful as part of a broader treatment plan.

5. Muscle Tension Dysphonia

Muscle tension dysphonia, often shortened to MTD, is one of the most common voice disorders seen in ENT and voice clinics. It happens when the muscles around the larynx become overworked or tense, disrupting the way the vocal cords vibrate.

Unlike some other voice disorders, MTD does not involve a structural abnormality or neurological damage. Instead, it is often rooted in how you habitually use your voice. Stress, anxiety, poor vocal habits, or compensating for another voice problem can all trigger or worsen MTD.

What it feels like: Your voice may sound strained, tight, or rough. You may experience vocal fatigue, throat tightness, or a feeling of effort when speaking. Some people also feel a lump-like sensation in the throat.

What helps: Voice therapy is the primary and most effective treatment for MTD. A speech-language pathologist can help you identify the habits that are creating tension and teach you healthier ways to produce sound. Many people see significant improvement with consistent therapy.

6. Paradoxical Vocal Fold Movement

Paradoxical vocal fold movement, also known as PVFM or vocal cord dysfunction, is a condition where the vocal cords close when they should be open. Normally, the vocal cords open wide during breathing to allow air in and out. In PVFM, they do the opposite, causing sudden episodes of breathing difficulty.

PVFM is often mistaken for asthma because the symptoms can look very similar. However, unlike asthma, PVFM does not respond to asthma inhalers. Common triggers include acid reflux, exercise, stress, cold air, smoke, and strong odors.

What it feels like: You may experience sudden shortness of breath, a tight feeling in the throat, noisy or labored breathing, or a sensation that your airway is closing. Episodes can be frightening, especially when they happen without warning.

What helps: Once properly diagnosed, PVFM is highly treatable. Voice therapy and breathing retraining are the main treatment approaches. Identifying and managing triggers, such as treating acid reflux or reducing stress, also plays an important role.

7. Psychogenic Aphonia

Psychogenic aphonia is a condition where a person loses their voice without any structural or neurological cause. The vocal cords appear normal on examination, but the voice still fails to function properly. This can be a partial loss, called dysphonia, or a complete loss of voice.

It is important to understand that psychogenic aphonia is not imagined or made up. It is a real and recognized medical condition. It is believed to be triggered by significant psychological stress, emotional trauma, anxiety, or unresolved emotional conflict. The brain and the body are deeply connected, and in some cases, emotional distress can manifest physically in the voice.

What it feels like: Your voice may suddenly become very weak, whispered, or disappear entirely. Interestingly, many people with psychogenic aphonia can still cough or laugh normally, because those actions use different neural pathways.

What helps: Voice therapy is typically the cornerstone of treatment and is often highly effective. A speech-language pathologist works with you to gently restore voice function. In many cases, working with a mental health professional alongside voice therapy leads to the best outcomes. There is no shame in this. Getting the right support is a sign of strength.

FAQs

1. How do I know if my voice change is serious?

A voice change that lasts more than two to three weeks is worth getting checked, even if it does not hurt. Hoarseness, a weak or breathy voice, or a voice that keeps cutting out are all signs that something may be going on. The sooner you get evaluated, the sooner you can get answers and start feeling better.

2. Can voice disorders go away on their own?

Some mild voice disorders, like acute laryngitis from a cold, do clear up on their own with rest and hydration. However, many voice disorders do not resolve without treatment. Conditions like vocal cord nodules, spasmodic dysphonia, or vocal cord paralysis typically need medical care. If your symptoms have lasted more than a few weeks, it is best not to wait and hope they go away.

3. What kind of doctor should I see for a voice disorder?

An otolaryngologist, also called an ENT doctor, is the right specialist to see for voice concerns. ENT doctors are trained to evaluate the larynx and vocal cords directly. In many cases, they will use a small camera to look at your vocal cords up close. They may also refer you to a speech-language pathologist who specializes in voice therapy.

4. Is voice therapy really effective?

Yes, voice therapy is highly effective for many voice disorders, including muscle tension dysphonia, vocal cord nodules, paradoxical vocal fold movement, and psychogenic aphonia. A trained speech-language pathologist will work with you to identify what is causing the problem and teach you healthier ways to use your voice. Many patients see noticeable improvement within just a few sessions. At Colorado Voice Clinic, we work with Kathe Perez, a speech pathologist for voice therapy. 

5. Can stress really affect your voice?

Absolutely. Stress and anxiety can cause muscle tension throughout the body, including in the muscles around the larynx. This can lead to conditions like muscle tension dysphonia or even psychogenic aphonia, where the voice is lost without any structural cause. If you notice that your voice problems tend to get worse during stressful periods, that is important information to share with your doctor.
