The Eliza app asks users to record a voice memo, say, venting about an issue they're dealing with at work or simply reflecting on their day. The app turns the user's speech into text that's ready for sentiment analysis. After each memo is quickly analyzed, Eliza generates an infographic that shows users whether they sound happy and calm, mostly, or maybe stressed and in need of support from friends and therapists. It also lets users see, over time, how they've been feeling. The idea is to get people to counseling, or at least to talk with someone they love and trust before they find themselves dealing with unmitigated and debilitating levels of depression, anxiety or other mental health issues.
