Even If You Don’t Say Them Out Loud This Wearable Camera Recognizes Voice Commands
Video summary
Cornell researchers developed SpeeChin, a necklace-worn infrared camera that captures chin and neck movements to recognize silent, whispered, or mouthed speech. It distinguishes 54 English phrases and 44 Mandarin words, achieving 90.5% accuracy for English and 91.6% for Chinese in tests with 20 people; accuracy falls when users move. The device aims to enable discreet voice commands in quiet or socially sensitive settings but requires further reliability improvements before commercial availability.
