System and method for determining the interpolation coefficient sets

摘要

Methods for determining interpolation coefficients set by electronic device is described. The method includes determining a value based on the characteristics and properties of the previous frame of the current frame. The method also includes determining whether the value is outside the range. The method further includes if the value is outside the range, based on the values and the prediction mode indicator, includes determining an interpolation coefficient sets. Method additional comprises synthesizing a speech signal.
