Starting from the Speaker 3.3.4 version, the feature of saving data about the generated audio file in meta fields has been added.

- speaker-duration – the audio file duration of the current post/page.
- speaker-filesize – the audio file size of the current post/page specified in bytes.
- speaker-timestamp – the date and time the audio file was created.
- speaker-url – the audio file URL of the current post/page
