About this study
Official title: A Prospective, Randomized, Multi-Centered Clinical Trial to Investigate the Effectiveness of Smartphone-Based Speech Therapy for People with Post-Stroke Dysarthria
This clinical trial aims to determine if a new smartphone-based speech therapy is effective self-treatment method for patients with post-stroke dysarthria. For this study, participants in the intervention group will use the speech therapy app for 1 hour per day, 5 days per week, over a 4-week period. The active control group will receive home-based speech therapy with the same duration and frequency as the intervention group.
The study will help us understand if smartphone-based speech therapy is a viable treatment option for post-stroke dysarthria patients.
Read the detailed description
In this study, 100 patients with post-stroke dysarthria will be recruited and stratified into acute-subacute (within 1 month after index stroke) and chronic (after 6 months after index stroke) groups. Participants will then be randomly assigned to either the intervention or active control group.
Patients in the intervention group will use a smartphone-based speech therapy app that includes oro-motor exercise, phonation, articulation, resonance, syllable repetition, and reading exercises. Treatment goals and contents will be determined based on individual patient conditions by a speech-language pathologist after the baseline evaluation. Participants will receive daily sessions for 1 hour per day, 5 days per week, over a 4-week period.
Patients in the active control group will receive home-based speech therapy, which includes oro-motor exercises and reading tasks from a workbook, for the same frequency as the intervention group. Both groups will also receive usual stroke care.
The study aims to evaluate the efficacy of mobile-based speech therapy compared to home-based speech therapy in improving speech intelligibility scores 4 weeks after baseline for patients with dysarthria in the acute-subacute and chronic phases following stroke.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Smartphone-based speech therapyDevice
Participants will be instructed to use the speech therapy app for 1 hour per day (5 days for 1 week) over a 4-week period.
Home-based speech therapyOther
Participants will receive treatment maintaining the same frequency as the intervention group.
| Study group | Role | What they receive |
|---|---|---|
| Smartphone-based speech therapy with usual stroke care | Experimental | Smartphone-based speech therapy: Participants will be instructed to use smartphone-based speech therapy (application), including oro-motor exercises, phonation, articulation, resonance, syllable repetition, and reading exercises.
Usual stroke care: Participants will follow the treatment as usual, including conventional stroke therapy if needed based on the medical guidelines. Receives: Device: Smartphone-based speech therapy |
| Home-based speech therapy with usual stroke care | Active comparator | Home-based speech therapy: Participants will receive treatment such as oro-motor exercises and reading tasks from a workbook.
Usual stroke care: Participants will follow the treatment as usual, including conventional stroke therapy if needed based on the medical guidelines. Receives: Other: Home-based speech therapy |
What is being measured
The primary outcome is the main question the study is designed to answer.
Speech intelligibility
The change in speech intelligibility from baseline to 4 weeks post-intervention will be assessed. Speech intelligibility will be evaluated by having three naive listeners transcribe the participants' recorded speech. These transcriptions will then be compared to the original sentences to calculate a percentage score representing intelligibility. The final intelligibility score will be calculated as the average of the scores from the three naive listeners. A higher percentage indicates greater speech intelligibility.
Measured: Baseline, 4 weeks
Secondary outcomes (3)
Maximum phonation Time (MPT)
The change in maximum phonation time (MPT) from baseline to 4 weeks post-intervention will be assessed. MPT will be used to assess participants' maximum phonation time. The speech evaluator instructs the patient to take a comfortable breath and then produce the sound /a/ for as long as possible. The task is performed twice, and the maximum duration of the two measurements is used.
Measured: Baseline, 4 weeks
Oral-diadochokinesis (DDK)
The Oral-diadochokinesis (DDK) change from baseline to 4 weeks post-intervention will be assessed. DDK will be used to assess articulation rate, regularity, and accuracy. Participants are instructed to repeat the syllables /pa/, /ta/, /ka/, and /pataka/ as quickly and accurately as possible. The number of repetitions is divided by the duration of the task.
Measured: Baseline, 4 weeks
Percentage of Consonants Correct (PCC, %)
The Percentage of Consonants Correct (PCC, %) change from baseline to 4 weeks post-intervention will be assessed. PCC is evaluated as a percentage score calculated from the Urimal Test of Articulation and Phonology 2 (UTAP2).
Measured: Baseline, 4 weeks

Primary outcome
Speech intelligibility
Time frame: Baseline, 4 weeks
The change in speech intelligibility from baseline to 4 weeks post-intervention will be assessed. Speech intelligibility will be evaluated by having three naive listeners transcribe the participants' recorded speech. These transcriptions will then be compared to the original sentences to calculate a percentage score representing intelligibility. The final intelligibility score will be calculated as the average of the scores from the three naive listeners. A higher percentage indicates greater speech intelligibility.
