What mp4 supports listening to novels or how to make MP4 listen to novels

There were many MP4s on the market that supported listening to novels. For example, e-book readers usually had a TTS(Text to Speech) engine that could convert novels into voice output. In addition, there were also some specialized novel listening devices such as hand-held MP4 or e-book players, which had built-in audio decoding devices that could decode and play the audio files in the e-book. In order for the MP4 to support reading novels, the novel had to be converted into a format that could be played on the MP4, such as e-book format or MP3 format. You can use some e-book readers or audio decoding software to convert the novel into an MP4 format. In addition, you can also import the novel into the MP4 and set the MP4 to read mode to listen to the novel in the MP4.
