User's voice signal from the helmet vibrations. It works!
Vibration sensors can pick up speech signals by detecting tiny vibrations of any surface caused by sound. One example is bone-conducted vibrations triggered by the user’s voice and detected by the sensor mounted in an earpiece. In the video Dr. Alexander Goldin recorded at Knowles Corporation booth at the Global Audio Summit in Shanghai in March 2024, the sensor was mounted in a helmet that picked up the vibrations of his skull during his talk.
Alango OnlyVoice prototype vs. Apple Airpods Pro and Jabra Elite 7 Pro. Noise Reduction Performance in 3 Scenarios
A bone conduction sensor combined with external beamforming microphones can provide excellent voice pickup performance even in noisy environments. This video compares the Apple AirPods Pro and Jabra Elite 7 Pro with Alango's OnlyVoice™ Technology. Each of which combine the voice signals of an internal bone conduction sensor with external beamforming microphones.

Sound Effect Normalization
Do you like watching movies? Sporting events? TV shows? Have you noticed that they are getting noisier and noisier as time goes by, making it more and more difficult to follow the dialogue? Or, at least, is that what you feel is happening? If so, you may think there is nothing you can do to make the background noise softer and less annoying, the speech more intelligible, and the whole experience more enjoyable. You are right, you cannot. However, technology can. Alango Technologies is introducing a revolutionary VoiceFirst™ technology (previously known as SEN or Sound Effect Normalization) . Activate VoiceFirst™ technology on your device and enjoy listening again, as before, as it should be: the proper mix of music, sound effects, and spoken dialogue.
