Ultrasound Tongue-Reading Turns Silent Talk Into Speech
A prototype uses an under-the-chin ultrasound probe to read tongue movements and translate them into decoded speech, enabling private, sound-free communication. With about 50 hours of training data, it achieves roughly 15.6% error and can generalize across speakers with similar accents, though the current probe is bulky; future versions could resemble a wearable patch.
