When I use the Svox Pico or Piper speech synthesizers during reading, the word read is not highlighted and the reading does not change pages automatically.
If I use eSpeak-ng when reading, the text read is highlighted and when the reading reaches the bottom of the page there is a page change, see screenshot below.
I used Calibre 6.13 on Debian 12.
Is there any customization or option from Calibre to enable the playback tracking feature?
