The scratchy throat that comes with a cold is familiar to most, but for a professional voice user, it can mean canceled shows, sessions, and increased risk of injury. Usually the voice recovers on its own over time, but when it doesn't, it can signal injury.
How common is hoarseness after an illness?
The American Academy of Otolaryngology–Head and Neck Surgery Foundation (AAO-HNSF) estimates that about one in three people will have a voice problem at some point in their lives. The AAO-HNSF lists the common cold and other upper respiratory infections, voice overuse, acid reflux, and allergic laryngitis among them.²,³
Why does getting a cold change your voice?
Laryngitis means inflammation of the larynx, or voice box. The vocal folds are delicate tissue, and inflammation results in stiffness, making it hard to voice. The voice symptoms of laryngitis are:
Lowering of the speaking pitch
Increased effort to use the voice and project
Pitch breaks or pitch irregularities
The top of the vocal range becomes less accessible
Vocal break/passaggio becomes harder to navigate
What helps is simple: rest the voice as much as possible, drink plenty of fluids, use a humidifier, and avoid throat irritants like smoke. For professional voice users who must work on swollen cords, get checked immediately by a laryngologist to avoid injury from performing on swollen cords. The AAO-HNSF patient guidance adds that you should limit how much and how loudly you talk, use a microphone if you can, and be aware that some drying medications, such as certain antihistamines and diuretics, can make things worse.²
When should I get checked if I'm hoarse?
The AAO-HNSF guidelines recommend evaluation for hoarseness that has not resolved or improved within four weeks (sooner if a serious underlying cause is suspected).¹
ASHA uses a stricter public message: hoarseness or a raspy voice lasting longer than two weeks, pain with speaking or singing, frequent throat clearing, vocal fatigue, or difficulty projecting should prompt an evaluation.⁴
Center for Vocal Health prioritizes injury prevention, meaning exams should happen within 1–2 days of a change in voice that does not improve with rest. The risk of vocal injury is highest when working on cords with laryngitis. The best chance of avoiding injury is intervening early, 1–2 days if your career is your voice.
Is hoarseness always laryngitis? What are other causes of hoarseness?
When hoarseness is not associated with illness, it can be due to an endless list of causes, including:
Vocal overuse and injury
Nerve and movement problems. A weakened or paralyzed vocal fold can follow an illness. One well-known example is Google co-founder Larry Page, who has described how hoarseness after a cold led to a diagnosis of paralysis in one vocal fold.⁵
Cancer. Laryngeal cancer is uncommon, but it is one reason that persistent hoarseness should never be ignored.⁶
What exam should I have done if I'm hoarse?
The key test is a stroboscopy, a look at the vocal folds with a small camera to detect microscopic causes of hoarseness. This is a quick and painless examination and is the most precise diagnostic tool we have to determine the cause of hoarseness.
