Celestia is now available on the 15.ai voice generator following the release of Rarity a few weeks ago. She's a bit more limited compared to the other characters due to lack of voice data, but you can still have her say various things if you mess with the text enough.
We will most likely do a second event here soon, so keep an eye out for that! for now, go mess with Celestia.
And in other news, Twilight, Fluttershy, and Rarity have all been updated to sound a bit less robotic. Give them a shot!
