Echo Cancellation and Speech Enhancement

Paper abstract
This paper introduce the new solution of integrated system to acoustic echo and noise reduction in order to improve the speech intelligibility in communication with used of the hands-free devices. The filter bank is proposed with minimum requirement of the band quantity to approximate psychoacoustic scale with nonuniform bands design using the first order all-pass transformation. Proposed solution fit in application of the 16-bit signal and sampling rate from 8 kHz.
