06.773GPPMinimum Performance Requirements for Noise Suppresser Application to the AMR Speech EncoderTS

The present document specifies recommended minimum performance requirements for noise suppression algorithms intended for application in conjunction with the AMR speech encoder. This specification is for guidance purposes. Noise Suppression is intended to enhance the speech signal corrupted by acoustic noise at the input to the AMR speech encoder.

The use of this recommended minimum performance requirements specification is not mandatory except for those solutions intended to be endorsed by SMG11.

It is the intention of SMG11 to perform analysis and validation of any AMR noise suppression solution which is voluntarily brought to the attention of SMG11 in the future, using the requirements set out in this specification to facilitate such an analysis. In order for SMG11 to endorse such a solution, SMG11 must confirm that all the recommended minimum performance requirements are met.
