Dysarthria Speech Therapy: Exercises for Slurred or Quiet Speech
Dysarthria is weak, slow or poorly coordinated movement of the speech muscles, so speech comes out slurred, quiet, mumbled or monotone even though the person knows exactly what they want to say. It responds to targeted, measured, daily practice. Speech Vani Therapy’s dysarthria module has 61 exercises across six types, with librosa audio analysis of loudness, pitch and stability on every attempt, for use alongside a licensed SLP’s plan.
Who this is for
- People with Parkinson’s disease whose voice has become quiet or monotone and who are asked to repeat themselves constantly.
- Stroke and brain-injury survivors with slurred speech, often alongside aphasia or apraxia work.
- Adults with multiple sclerosis, cerebral palsy, motor neurone disease or another progressive condition, focused on maintaining intelligibility.
- Carers who want objective feedback rather than judging "was that loud enough?" by ear all day.
What causes dysarthria, and how is it different from aphasia?
Dysarthria is a motor problem. Damage to the nervous system weakens or de-coordinates the muscles of breathing, voicing, the soft palate, tongue and lips, so the message is intact but its execution is not. Common causes are Parkinson’s disease, stroke, traumatic brain injury, multiple sclerosis, motor neurone disease and cerebral palsy, and the sound varies by type — hypokinetic dysarthria in Parkinson’s is typically quiet and monotone, while ataxic dysarthria sounds irregular and drunken.
Aphasia is a language problem: the words themselves are inaccessible. Someone with dysarthria can usually write a perfect sentence they cannot say clearly; someone with aphasia often cannot retrieve the sentence at all. Apraxia is a third thing again — planning fails inconsistently. The three co-occur often after stroke, and the treatment differs sharply, which is why an SLP assessment should come before a programme.
Which dysarthria exercises improve clarity the most?
Loudness and rate usually give the biggest return. Speaking deliberately louder recruits the whole system — better breath support, firmer vocal fold closure, wider mouth opening — so clarity improves as a side effect, which is why loudness is such a productive single target. Slowing the rate and pausing between phrases buys the listener time and the speaker coordination.
Add over-articulation (exaggerating every consonant as if speaking to someone lip-reading), sustained phonation to build breath support, oral-motor range and strength work for lips, tongue and jaw, and prosody practice to restore stress and intonation where speech has flattened. The 61 exercises are grouped along these six lines. The realistic goal is intelligibility — being understood first time — rather than speech that sounds unchanged from before.
Does loudness training help in Parkinson’s disease?
Loudness-focused training is the best-evidenced approach for hypokinetic dysarthria in Parkinson’s, and the reason it works is a perceptual mismatch: people with Parkinson’s typically speak far more quietly than they think they are, so normal volume feels like shouting. Training recalibrates that internal gauge as much as it trains the muscles.
The platform includes daily loudness challenges with badges to sustain the habit, measuring actual loudness with audio analysis rather than asking you to judge by ear. To be plain about it: this is LSVT-inspired practice, not the LSVT LOUD programme, which is a trademarked protocol delivered intensively by certified clinicians. If you can access certified LSVT, do — and use this to keep the gains going afterwards, which is where most people lose ground.
How do we measure whether speech is getting clearer?
Impressions are unreliable, especially for family who have adapted to a familiar voice. Objective measures help: the module runs librosa audio analysis on each attempt to report loudness, pitch, duration and stability, so "louder" and "steadier" become numbers you can trend rather than opinions. Optional camera-based face tracking adds feedback on mouth opening and symmetry during exercises.
Pair that with a functional measure at home. Once a week, have the person read a few unfamiliar sentences to someone who has not heard them, and record what proportion was understood first time — intelligibility to an unfamiliar listener is the outcome that actually matters. In progressive conditions, holding steady is a genuine success, and honest tracking is what lets you see that instead of only seeing decline.
How often should someone with dysarthria practise?
Most days, in short sessions. Ten to fifteen minutes daily beats an hour on Sunday, because this is muscular and neurological training and it detrains quickly when stopped. Fatigue is a real limiter, particularly in MS and motor neurone disease, so practise when energy is highest and stop before speech deteriorates — pushing into exhaustion teaches the wrong pattern.
In progressive conditions the target changes over time, from improving clarity to maintaining it, and eventually to combining speech with AAC support. That is not failure; it is planning, and the AAC module exists for exactly that transition. Have an SLP set and revise the programme.
