Comparing DMS with Algorithms and Distances between Microphones.

Recent days, speech quality is one of the most important factors in mobile communication and the quality depends on Signal-to-Noise Ratio (SNR) improvement. Dual Microphone System (DMS) can recover a speech from noisy environment with the help of different algorithms. This paper contributes to reduce babble speech noise by developing the dual microphone system with two Omni-directional microphones for close talk handset mode in mobile phone. It can also find out the position of microphones in a mobile. This system is successfully compressed the babble noise and improve the quality of speech.
