Claim 7:
8. An apparatus for hangover addition for discontinuous transmission (DTX) in speech or audio coding, comprising:
a processor;
a memory coupled to the processor and storing instructions; and
wherein the processor is operable to execute the instructions to:
determine a primary decision based on signal activity;
determine a final decision based on whether a hangover addition of the primary decision is performed;
determine a short term activity measure based on past primary decisions;
determine a long term activity measure based on past final decisions or past primary decisions; and
adjust the hangover addition based on the short teiiu activity measure and the long term activity measure, wherein the processor is operable to add a first number of hangover frames if the short term activity measure exceeds a first threshold and to add a second number of hangover frames if the long term activity measure exceeds a second threshold.
