the core clinical goal of dysarthria therapy
Short, captioned explainers to send to a patient or their family after a session.
Dysarthria is a disorder of speech production tied to neuromuscular impairment: Parkinson's (hypokinetic), MS, post-stroke (spastic or flaccid), or ataxic (cerebellar stroke, hereditary ataxia). Patients present with varying degrees of hypophonia, imprecise articulation, and atypical speech rate.
ICD-10: R47.1Hypophonia: weak, breathy, or hoarse voice
Imprecise consonants: reduced range of articulatory movements
Atypical rate: too slow (spastic), rushed (Parkinson's), irregular (ataxic)
Monotone voice: loss of melodic variation (flat F0)
Reduced intelligibility in noisy settings
PA-TA-KA (diadochokinesis), oral-motor exercises, tongue twisters, texts loaded with complex consonants. Builds articulatory range and precision, following the principles of LSVT and Duffy (2019).
A dedicated module for vowel and consonant range. Measures the two main articulatory gestures in real time with visual feedback.
For patients with a monotone voice. Visualizes the melodic contour, 11 prosodic intents, segment-by-segment coaching.
These modules run right in your browser, microphone optional. This is what your patients see between sessions.

1. Initial assessment
Measure SPS. Subjective intelligibility rating. Calibrate the vocal baseline.
2. Motor exercises
PA-TA-KA, oral-motor exercises, tongue twisters. Combined articulation + loudness biofeedback when hypophonia is present.
3. Vocal projection
Reading with loudness biofeedback. Target: x1.3 to x2 vs resting voice.
4. Intonation
For patients with a monotone voice. Real-time F0 contour, 11 intents.
5. Follow-up
Between-session loudness curve. Replayable recordings. Goal adjustment.
Intensive, regular practice of articulation drills is the foundation of dysarthria therapy, regardless of etiology.

Loudness biofeedback helps recalibrate the perception of vocal effort in hypokinetic Parkinsonian dysarthria.

Remotely supervised home practice produces gains comparable to clinic-only therapy for mild-to-moderate dysarthria.
