These findings are preliminary and descriptive. Acceptance rates reflect the app’s automated speech recognition decisions, which have not been validated against SLP ratings, and may also reflect changes in app scoring over time. They should not be interpreted as clinical articulation accuracy, within-platform growth, or evidence of treatment efficacy.

Administrative drafts, prompts, correspondence, private source records and verification evidence are excluded from public downloads.
