An interventional study of Voiceitt in Speech Impairment and Speech Disorder, sponsored by University of Pittsburgh. Recruiting at 1 site in United States. Open to participants aged 13 Years and older. Per ClinicalTrials.gov, last updated 2026-09-04.
Sponsored by University of Pittsburgh · Not applicable, Interventional, and Other
The primary objective of this pilot study is to evaluate the feasibility and preliminary effectiveness of the Voiceitt app in improving communication for individuals with speech impairments due to conditions such as cerebral palsy (CP), stroke, Amyotrophic Lateral Sclerosis (ALS), or Parkinson's disease.
Conditions like CP, ALS, Stroke or Parkinson's disease, etc., cause communication impairment. There are few augmentative communication options that allow people with these impairments to communicate effectively.
Voiceitt is an app that is designed to assist people with speech impairments by using a voice recognition and dictation tool that adapts to users' unique, non-standard speech patterns. However, its effectiveness in clinical populations has not been established. This study is bridging the gap in evaluating the preliminary effectiveness and feasibility of Voiceitt app in improving communication among people with mild to moderate speech impairments.
77 studies on the registry are indexed under Speech Disorders; 20 are open to participants now.
This study's planned enrollment of 20 is below the median of 38 across 54 interventional studies indexed under Speech Disorders.

Change in Communication Abilities as measured by SIR
Change in Communication Abilities as measured by Speech Intelligibility Rating (SIR) that quantifies clarity of speech. The rating ranges from 1-5. low rating means speech is unintelligible, and highest rating means speech is intelligible to all listeners. Change in SIR is measured by administering SIR at 3 different time points, at baseline, and two times after intervention.
Time frame: Baseline (Day 1), 5-6 months, and 7-8 months
Change in Communication Abilities as measured by Communication Effectiveness Index (CETI)
Change in Communication Abilities as measured by Communication Effectiveness Index (CETI) that measures perceived effectiveness of communication in daily activities. CETI is a 16 item questionnaire. Each item is scored from 1-100. The final score of CETI is the averaged score across the 16 items, and ranges from 1-100. A high score indicates good performance in functional communication and a low score, poor performance. Change in CETI is measured by administering CETI at 3 different time points, at baseline, and two times after intervention.
Time frame: Baseline (day 1), 5-6 months, and 7-8 months
User Satisfaction
User satisfaction is assessed through surveys and interviews focusing on ease of use, satisfaction with the app, and perceived changes. The survey uses Likert-type scale where users choose the answer option that represent their assessment of the app on several usability questions. An example of the question-and-answer choices is "How easy was it to set up the Voiceitt app? Very easy, Easy, Neutral, Difficult, Very difficult." Reported data will be a combination of frequency of participants choosing favorable and unfavorable answer choices, and a qualitative analysis based on participants' responses to the survey and interview.
Time frame: 7-8 months
Change in Communication-Related Frustration
Self-reported change in frustration levels during communication.
Time frame: 7-8 months
Change in Participants' Accounts on Social Interaction Quality
Through qualitative interviews, participants will be asked about how the app influenced their social interactions and participation in daily activities. This information will be reported qualitatively as themes using qualitative analysis.
Time frame: 7-8 months

Started Jun 2025 (actual). Primary completion is estimated for Dec 2027, 30 months after the start.
Of 35 non-industry interventional studies with no phase under Speech Disorders, half reached primary completion within 28 months of starting (the median), counting those still running; a quarter within 17 and three quarters within 38. This study's planned 30 months is close to that.
Counting every sponsor, half of 37 studies reached it within 28 months; a quarter within 17 and three quarters within 38.
