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.

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.

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.
