This is still occurring in later versions of the same software. Should I also open a ticket with Ubuntu?

I expect this is to do with the availability (or rather, lack thereof) of espeak on your machine. You might need to install extra packages, or use a more recent version of a particular package. The web speech folks and/or Eitan would know more.
