Full Description

This technical report provides background information on the performance of the six candidates which were proposedas solutions for publication of an example noise suppression solution for application to the GSM Adaptive Multi-Rate(AMR) speech codec. Experimental test results from the speech quality related testing are reported to illustrate thebehaviour of the candidate algorithms in multiple operational conditions. Additional information is also providedcovering data not necessarily directly associated with speech quality (such as complexity, delay, effect on voice activityfactor).
