If you’ve ever wondered how others are feeling, well, now there’s an app for that.

Researchers at MIT developed an algorithm that can analyze the tone of a person’s speech. The system can give an emotional score to each five-second block of a conversation, and results can be viewed in real time through an application on a smartwatch.

Researchers tested people’s conversations by using an iPhone 5S to record audio and a wearable Samsung Simband to detect data such as heart rate and display the results.

The technology is still being developed, but researchers believe this is a step toward helping people with anxiety or social disorders like autism.
