Very impressive. I tested it with:

  In Sioux City the Taoiseach parked his coupe by the quay overlooking a fjord. Nearby, a bugle played an octave, children savored sherbet and quinoa with acai, and an artisan sold bagels next to ancient-inspired rouge.

And it got most of the (irregularly spelt) words pronounced correctly except for 'quinoa' and 'acai'.

Just for fun, I also tested some tongue twisters. For some reason, I find it psychologically very difficult to listen to perfectly spoken tongue twisters — almost as if some sort of nail on chalkboard effect is going on!

  She sells sea-shells by the sea-shore.
  The shells she sells are sea-shells, I'm sure.
  For if she sells sea-shells by the sea-shore
  Then I'm sure she sells sea-shore shells.

Honestly, I second guess myself any time I have to say “quinoa” or “açaí” out loud.

OP here. Thanks for the feedback! Yeah, those are some pretty tough sentences (obviously not in the dataset). The tongue twister one is really interesting.
