Acoustic Echo Cancellation with Adaptive Filtering

Because echo is formed through picking up sounds from the loud speaker by speaker microphone, echo noise in voice transmission systems severely degrades the speech quality and the speech intelligibility of speech signal. These picked sounds are sent to loudspeaker again. As a result of repetition of this process, the amplitude of the echo increases. In the study, it is aimed to enhance the intelligibility of speech by canceling out the echo noise. In this study, the data transfer software which is necessary for real time processing of voice signals and the adaptive filtering algorithm software for the application of acoustic echo cancellation have been developed
