In plain words

TS 26.077 specifies "recommended minimum performance requirements for noise suppression algorithms intended for application in conjunction with the AMR speech encoder". Noise Suppression is intended to enhance the speech signal corrupted by acoustic noise at the input to the AMR speech encoder. For speech calls where the narrowband AMR codec is utilised, this feature shall be applicable as an option, while provision in AMR-capable mobile stations is a manufacturer dependent option.

How this page was made

The facts box and the tables come straight from the 3GPP specification archive and CR database as indexed by 3GPP Scout. An AI model (GPT-6 Luna) wrote the paragraph and named the source of each sentence. Code checked every quote word for word against the stored source text and every number against the cited source. A second AI model from another company (Claude Opus 5.5) reviewed the paragraph against the same sources. The 3GPP documents themselves govern.
