摘要

A transmission system has a speech encoder and a speech decoder. From frames of speech signal samples, the speech encoder derives data frames with coefficients representing the frames of speech signal samples. The data frames, that include complete and incomplete data frames, are transmitted to a speech decoder. As compared to a complete data frame, an incomplete data frame carries an incomplete set of coefficients. The speech decoder introduces additional coefficients into incomplete data frames. The additional coefficients represent frames of speech signal samples that are later in time than the frames of speech signal samples corresponding to the incomplete data frames. The speech decoder uses the additional coefficients to complete incomplete sets of coefficients.
