Text to speech voices sounding different?

[Meeps]

Am I going insane? Did they change the Wavenet voices for Text to Speech? This past week I have noticed the voices have been lower quality and they sound vastly different. I've talked to a few friends who confirmed my findings. What's going on? Am I doing something wrong? Was there a change? Why didn't they announce a change? Or did they announce it and I missed it. Are the servers somehow overloaded and they are serving lower quality audio? I'm just confused. Users generally a very tied to how a voice sounds and the recent change has been upsetting for many of those people.
