A method may include obtaining audio originating at a remote device during a communication session conducted between a first device and the remote device and obtaining a transcription of the audio. The method may also include processing the audio to generate processed audio. In some embodiments, the audio may be processed by a neural network that is trained with respect to an analog voice network and the processed audio may be formatted with respect to communication over the analog voice network. The method may further include processing the transcription to generate a processed transcription that is formatted with respect to communication over the analog voice network and multiplexing the processed audio with the processed transcription to obtain combined data. The method may also include communicating, to the first device during the communication session, the combined data over a same communication channel of the analog voice network.
