A method for generating voice in an ongoing call session based on artificial intelligent techniques is provided. The method includes extracting a plurality of features from a voice input through an artificial neural network (ANN); identifying one or more lost audio frames within the voice input; predicting by the ANN, for each of the one or more lost audio frames, one or more features of the respective lost audio frame; and superposing the predicted features upon the voice input to generate an updated voice input.
