IIT Guwahati Develops Sensor for Silent Voice Communication
Researchers from IIT Guwahati and Ohio State University made a special sensor that works underwater to help people who can't speak.
When you try to speak, even without making a sound, air comes out of your mouth.
This sensor picks up the tiny waves the air makes in water.
It then uses smart computer programs to understand what you're trying to say, so you can control devices without needing to speak.
The current version costs around Rs 3,000.
IIT Guwahati and Ohio State University created an underwater vibration sensor.
The sensor enables contactless voice recognition by detecting breath patterns.
It aims to aid people with speech disabilities by interpreting breath-induced water waves.
The prototype utilizes Convolutional Neural Networks (CNN) to interpret data.
Potential applications include integration with voice-assistive technologies and smart devices.
