Phonology: Speech Therapy is a third-generation app developed by Austin Speech Labs, a non-profit organization focused on providing speech therapy to stroke survivors. The app, now available on the App Store, is designed to assist both speech therapists and clients in in-person and remote sessions. Users can practice identifying and producing sounds, focusing on vowels, consonants, or custom sound sets. The app includes a Progress Tracker to monitor performance and offers extensive customization options tailored to individual needs.

Phonology's free features comprise sound identification and production using pictures, in-session progress tracking, and app customization. The Pro version enhances these features with combinations of pictures, letters, and videos for sound identification, personalized sound sets, multiple profile support, detailed progress tracking, and more.
