Speech Enhancement in Microphone systems

Speech Enhancement in Microphone systems

Abstract

The use of microphones and audio devices are becoming more relevant every year. Speech audio is used to communicate between humans and recently often to communicate with devices as well. Hearing loss and noisy spaces are an increasing problem which makes it harder to communicate. It is therefor important to come up with techniques to enhance the desired speech signal from a noisy environment. This comes with many challenges including correlating noises,  dynamic noise energies and interference noise. This report discusses the work done on the mini-project for the course “IN4182 – Digital Audio and Speech Processing” in which a single microphone speech enhancement system is designed.
