What is voice therapy?
Voice therapy is a behavioural treatment delivered by a speech-language pathologist (SLP), often working with an ENT specialist. It aims to produce the best possible voice with the least effort by improving breathing, vocal fold closure, resonance, pitch and loudness, and by changing harmful habits. It is evidence-based for many functional and some organic voice disorders and is often the first-line treatment. See hoarseness and vocal warm-ups.
Who benefits from voice therapy?
- Muscle tension dysphonia: strained, tired or rough voice from excessive muscle effort.
- Vocal nodules, polyps and cysts, often caused by voice overuse.
- Professional voice users: teachers, singers, actors, call-centre staff, coaches. See vocal exercises for singers.
- Vocal cord paralysis or paresis, before or after injection or surgery. See vocal cord paralysis.
- Presbyphonia: weak, breathy ageing voice.
- Parkinson’s disease with a soft, monotone voice (LSVT LOUD).
- Paradoxical vocal fold motion and chronic cough, with breathing retraining.
- Spasmodic dysphonia, as an adjunct to botulinum toxin.
- Voice and communication for transgender and gender-diverse people.
- Voice problems after laryngeal surgery or radiotherapy.
What happens in the first session
- A case history: voice use, symptoms, medical history, reflux, medicines, smoking and alcohol, hydration, work and hobbies.
- A voice assessment: listening to your voice, measuring pitch, loudness, maximum phonation time and sometimes acoustic analysis.
- A review of the laryngoscopy findings from your ENT, which show the vocal cords.
- Goals agreed, usually a plan of weekly sessions over 4–12 weeks with home practice.
- Education about how the voice works and what harms it.
Vocal hygiene: the foundations
- Drink water regularly; aim for pale urine.
- Avoid smoking, vaping and heavy alcohol; limit caffeine and very dry environments.
- Avoid habitual throat clearing and coughing; swallow, sip water or use a silent cough.
- Avoid shouting, whispering and talking over noise; use amplification if needed.
- Rest the voice after heavy use and during illness.
- Treat reflux, allergies and postnasal drip. See laryngopharyngeal reflux and postnasal drip.
- Get adequate sleep, and manage stress, which tightens the throat muscles.
- Warm up before extended voice use.
Typical exercises
- Diaphragmatic breathing: a relaxed belly breath with a smooth exhale on “sss” or “shh”.
- Semi-occluded vocal tract (SOVT) exercises: humming, lip trills, tongue trills and phonating through a straw into water or air; they reduce vocal fold impact and ease the voice.
- Resonant voice therapy: producing a forward, buzzing sensation on “m” and “n” words with easy onset.
- Laryngeal massage and neck and shoulder relaxation for tension.
- Vocal function exercises: sustained notes, glides and pitch ranges to strengthen and balance the system.
- Easy onset: starting words gently, particularly those beginning with vowels.
- LSVT LOUD: an intensive programme (four sessions weekly for four weeks) for Parkinson’s disease, focusing on louder speech.
- Carry-over: practice in conversation, phone calls and work situations.
How long does it take?
Many people notice improvement within 2–4 weeks, with a full programme lasting 4–12 weeks, depending on the problem. Home practice, usually 5–15 minutes several times a day, is essential. Voice therapy can reduce or remove the need for surgery in nodules and polyps; when surgery is required, therapy before and after improves results.
Online voice therapy
Telepractice is effective for many voice problems and widely available, especially when an ENT has already examined the cords. Good audio, a quiet room and a camera help the therapist assess posture and technique. In-person sessions may be preferred for complex cases, post-surgery care or hands-on techniques.
When to see a doctor first
- Hoarseness lasting more than 3–4 weeks (2 weeks in smokers).
- Voice change after neck, thyroid or chest surgery, or intubation.
- Breathing difficulty, noisy breathing, trouble swallowing or aspiration.
- A neck lump, coughing blood, ear pain or unexplained weight loss.
- Sudden loss of voice.
- Children with persistent hoarseness.
- Any suspected serious cause requires examination of the vocal cords before voice therapy.
Three common situations
A teacher with an end-of-day hoarse voice and vocal nodules: voice therapy with hygiene, SOVT exercises and amplification.
A person with Parkinson’s disease whose voice has become soft: LSVT LOUD or similar loudness training.
A smoker with hoarseness for six weeks: medical examination first, then therapy if appropriate.
Voice therapy for children
Children can develop hoarseness from shouting, vocal nodules, reflux or frequent colds. Treatment focuses on vocal hygiene and play-based exercises, often with the family involved: reducing shouting, encouraging water, replacing loud play with quieter alternatives, and teaching easy, relaxed voice use. An ENT examination is advised for persistent hoarseness, because structural causes are treated differently. Many children improve with therapy and with maturity, and surgery is rarely needed.
A five-minute daily routine
- One minute of relaxed belly breathing with a long “sss” exhale.
- One minute of lip trills or humming, gliding up and down comfortably.
- Two minutes of straw phonation, blowing bubbles in a glass of water while gliding the pitch gently.
- One minute of easy-onset reading aloud, starting each sentence gently.
- Sip water throughout, and finish with a gentle neck and shoulder release.
- Do this once or twice a day, as your therapist recommends, and stop if the voice or throat feels tired or sore.
Key points to remember
Voice therapy retrains how you use your voice, and is often the first-line treatment for many voice problems. Get your vocal cords checked, then commit to a programme and home practice. Our speech therapy team can help you recover your voice.

Questions about voice therapy
These answers are general information and do not replace an examination or individual medical advice.
What is voice therapy?
A programme of exercises and habit changes with a speech-language pathologist to improve voice quality and comfort.
Does voice therapy work?
Yes, for many voice problems including nodules, tension dysphonia and age-related voice change.
How long does it take?
Often 4–12 weeks with regular home practice.
Do I need to see an ENT first?
Yes, a vocal cord examination is advised before therapy to rule out serious causes.
What is straw phonation?
Making sound through a straw, which reduces vocal strain and helps retrain the voice.
Can voice therapy avoid surgery?
In many cases yes, particularly with nodules and functional problems.
