MIT's new AI understands the hardest part of human language

Voice-based artificial intelligence assistants can understand human speech better than ever. But while AI can decipher our words and context to deliver fast results and actions, AI doesn't understand the tone, or one's feelings. Researchers from MIT set out to change that, creating a wearable that can detect the tone of a conversation. In the future, the tool might help people with anxiety or Asperger's syndrome better deal with stressful situations. Researchers from MIT's Computer Science and Artificial Intelligence Laboratory (CSAIL) and Institute of Medical Engineering and Science (IMES) published their findings on an AI-based wearable system that would correlate audio and vital-sign data to act as a social coach for the wearer.
