| 摘要 |
A method and apparatus for detecting previous packet loss in non-packetized speech by applying one or more filters to a segment of said non-packetized speech, each of said one or more filters determining an energy parameter value for a given frequency band of said segment of said non-packetized speech; comparing one or more of said determined energy parameter values to one or more corresponding thresholds; and detecting previous packet loss based on said comparison of said one or more of said determined energy parameter values to said one or more of said corresponding thresholds.
