It is espeak bug,
https://sourceforge.net/tracker/?func=detail&aid=3123010&group_id=159649&atid=812675
there is a patch that works for me. You can build espeak from sources
if don't want to wait for new version in distros.
(I had to tweak svn version, looks like it is in the middle of starting
using libsonic library and build process is not settled down. you can
just build one of recent versions w/o sonic.)

There is also another mark tracking related bug
https://sourceforge.net/tracker/?func=detail&aid=3123018&group_id=159649&atid=812675

I also fixed a bug in gst-espeak when current mark might return to previous position
