Method and System for Processing Channel B Data for AMR and/or WAMR

A machine-readable storage having stored thereon, a computer program having at least one code section for signal processing, the at least one code section being executable by a machine for causing the machine to perform steps comprising:

• generating, within a receiver that receives voice data comprising at least a first channel data and a second channel data, if said first channel data passes verification and said second channel data is unacceptable based on one or more error measurement metrics, one or more second channel data hypotheses for a present speech frame;
• generating one or more speech hypotheses for said present speech frame, wherein each of said one or more speech hypotheses is based on a corresponding one of said one or more second channel data hypotheses and said first channel data;
• and
• selecting a present speech data from said one or more speech hypotheses.

A system for signal processing, the system comprising:

• one or more circuits, within a receiver that receives voice data comprising at least a first channel data and a second channel data, that enable generation of one or more second channel data hypotheses for a present speech frame, if said first channel data passes verification and said second channel data is unacceptable based on one or more error measurement metrics;
• said one or more circuits enable generation of one or more speech hypotheses for said present speech frame, wherein each of said one or more speech hypotheses is based on a corresponding one of said one or more second channel data hypotheses and said first channel data;
• and
• said one or more circuits enable selection of a present speech data from said one or more speech hypotheses.
