Shout-out to those who remember this TTS as Ivona which was a hit in Poland. Just when YouTube took of it was used and abused to make a crap ton of parody videos, most bad, some good [1] - and then people were so much sick of it that new parody videos promised "No Ivona" in the title [2].
Now you can hear one of the voices "Ewa", "Jacek", "Maja" on most train stations announcing arrivals and departures through the PA [3].
