A novel concept of Smart Headphones using Active Noise Cancellation and speech recognition

This project presents an engineering low cost solution to a contemporary issue of speech recognition in a headphone. The “Smart Headphone” has been brought out as a prototype design in which two principles of Active Noise Cancellation (ANC) have been achieved using a Digital Signal Processor (TMS320C5416). The system will detect the surrounding environment in real time and process the significant information to the user and thereby reducing the risk of accidents. It can warn users of incoming traffic (e.g. fire engines and ambulances) nearby and surrounding danger. It can be controlled by the user's voice commands; such as increasing or decreasing volume with the help of an interface controlled by a microcontroller (MSP430F2013) and the voice recognition module VR 3.1. The multifunction intelligent headphone will also notify the user if someone is trying to talk to them. The system presented here has profound implications for future studies of Wearable Computing and would help the society in a great way reducing the amount of traffic accidents suffered by people due to wearing headphones while driving or walking unaware of the surroundings.
