Adaptive code enhancement includes receiving feature data of a speech waveform having a plurality of frames, inferring a bitrate based on a quantity of bits of the plurality of frames received from the decoder codec, generating one or more latent feature vectors in accordance with the bitrate and based on the feature data, receiving one or more pitch lags and a speech signal, calculating filter coefficients on a per-frame basis based on the one or more latent feature vectors and the one or more pitch lags, and modifying the speech signal using the one or more filter coefficients to generate a modified speech signal.
