Talking ultrasound

Near real-time speech regeneration for voice-loss patients using ultrasonic speech for phoneme detection and classifi cation is under development by researchers at Nanyang Technological University in Singapore. Their research is important for a range of applications including: prosthesis for voice-loss patients; improving the performance of artifi cial speech recognition systems, especially in the presence of audible acoustic noise; and for the more private use of mobile telephones in public.
