The purpose of this study is to gather longitudinal data to examine how speech features and symptoms change over different intervals of time and the reliability of repeated, high frequency test administration. Participants will complete a variety of speech and language tasks using the Winterlight Assessment (iOS app) everyday for 30 days. The following is the list of assessments that participants will complete; 1) Daily assessment of mood, 2) Winterlight assessment which contains a series of verbal response tasks where participants are recorded through a tablet app, and 3) Clinical assessments.
