Speech Therapy for Parkinson's Disease : What is Lee Silverman Voice Treatment UK?
Originally Published in 2023 but updated in 2025 to fully reflect latest information for voice therapy
What Is Lee Silverman Voice Treatment (LSVT LOUD®) in the UK?
Lee Silverman Voice Treatment (LSVT LOUD®) is an evidence-based Speech and Language Therapy programme designed to help people with Parkinson’s disease improve voice loudness, clarity, and communication confidence.
Developed in the USA and now widely used in the UK, LSVT LOUD® retrains the brain and body to use a stronger, clearer voice. Research also shows benefits for people with other neurological conditions such as stroke, multiple sclerosis (MS), and traumatic brain injury (TBI).
Speech and Language Therapists offering this programme must complete specialist LSVT LOUD® certification training and an exam to deliver it effectively.
How Can Parkinson’s Disease Affect Speech?
Parkinson’s disease can affect the voice and speech muscles, leading to changes such as:
Speaking too quietly or softly
Monotone speech with little variation in pitch
Hoarse, breathy, or weak voice
Mumbled or unclear articulation
Reduced facial expression or emotion while speaking
Many people with Parkinson’s don’t realise their voice has become quieter, due to reduced sensory awareness.
In therapy, we recalibrate your awareness of loudness, helping you project your voice naturally and confidently.
Improving speech can also boost confidence, social interaction, and emotional wellbeing.
How does LSVT LOUD® help people with Parkinson’s disease?
LSVT LOUD® focuses on the principle of “Think Loud!”
It helps retrain the brain to produce a louder, more powerful voice through structured, high-effort speech exercises.
The programme includes:
1 assessment session to establish a baseline
16 therapy sessions (4 per week for 4 weeks)
Each session lasts 60 minutes
Daily home practice to reinforce progress
Research also shows improvements in swallowing and voice quality for people with Parkinson’s.
How effective is LSVT LOUD and how long do results last?
LSVT LOUD® has decades of research showing improved loudness, clarity, and confidence in speech. Results can last 1–2 years or longer with regular practice and occasional refresher sessions with your Speech and Language Therapist.
Can Lee Silverman Voice Treatment (LSVT LOUD®) be done Online?
Yes — online LSVT LOUD® therapy is clinically proven to be as effective as in-person sessions.
Virtual therapy allows you to receive specialist, intensive treatment from home, which can be especially helpful for those with mobility challenges.
We use secure video platforms such as Zoom, allowing you to record your voice for real-time feedback. Many clients find online therapy more accessible and motivating, fitting seamlessly into their daily routine.

No - you can be seeing within one week of your consultation.
