In 2019, Amazon upgraded its Alexa assistant with a feature that enabled it to detect when a customer was likely frustrated — and respond with proportionately more sympathy. If a customer asked Alexa to play a song and it queued up the wrong one, for example, and then the customer said “No, Alexa” in an upset tone, Alexa might apologize — and a request a clarification.

Now, the group behind one of the data sets used to train the text-to-image model Stable Diffusion wants to bring similar emotion-detecting capabilities to every developer — at no cost.
