ABSTRACT:
A speech decoder having a muting circuit which mutes the output of decoded speech when either the accumulated number of error-correcting codes corrected or the number of error-detecting codes detected within a received signal frame exceeds the set threshold value. Because that part of the decoded speech which fails to meet a reference level is suppressed, noise is eliminated from the decoded speech.
