Abstract:
This paper intends to analyze the performance of the widely used Enhanced Variable Rate Codec (EVRC) algorithm for suppressing background noise in speech Signals and propose a method for improving the current noise suppression capability of the algorithm. Firstly, the current EVRC algorithm is implemented on the TMS320C6713 based DSK in order to verify the algorithm and also to validate the real time performance of it. Then, based on the results and further analysis of the algorithm, a modification to the EVRC algorithm is proposed, which further improves the performance of it tremendously. This increase in performance of the proposed modified algorithm is ascertained by implementing the same on the DSK and obtaining relevant results.
