This project from the University of Bristol uses ultrasound beams to allow people to whisper and communicate verbally with each other even at a great distance. The technology was developed for Special Service agents and Special Force troops. Led by engineer Asier Marzo, 'Project Telepathy: Targeted Verbal Communication Using 3D Beamforming Speakers and Facial Electromyography' allows users to speak to each other privately and quietly up to 30 meters away from each other.
Electrodes need to be attached to the jaw and around the lips and a speaker must be worn on the chest or head. The electrodes read facial movements and the speaker sends ultrasound beams to make the system audible. An algorithm identifies 10 words that are translated with an 80% accuracy when mouthed silently.

Trend Themes
1. Ultrasound Communication - Using ultrasound beams for long-distance whisper communication presents opportunities for secure and private communication in various industries.
2. Targeted Verbal Communication - Developing 3D beamforming speakers and facial electromyography technology opens up possibilities for discreet and efficient communication in specialized fields.
3. Silent Speech Recognition - Advancements in silent speech recognition algorithms hold potential for improved accuracy and usability in interpreting silent mouthed words.
Industry Implications
1. Military and Defense - Implementing ultrasound communication technology can offer secure and discreet communication channels for special service agents and special force troops.
2. Security and Surveillance - Utilizing targeted verbal communication technologies can enhance covert communication capabilities in security and surveillance operations.
3. Healthcare and Assistive Devices - Applying silent speech recognition in healthcare and assistive devices can facilitate communication for individuals with speech impairments or language barriers.
