1. A method to correct for packet loss in an audio signal in an automatic speech recognition system comprising reconstructing the signal using linear interpolation from preceding and succeeding frames of audio, wherein the linear interpolation comprises the steps of: a. determining spectral vectors from a time interval of frames prior to a packet loss event; b. maintaining a sliding buffer, comprising a number of frames, between the time interval of frames and the packet loss event; c. generating the linear interpolation for the time interval of frames; d. using energy of the signal to tag frames within the packet loss event; and e. inserting values for the packet loss event into the sliding buffer.
