female US English voice of Siri sounds different in iOS 8.1.3

Has anyone noticed how Siri sounds more robotic now?
I have tested all the voices, and every one of them has the same expressiveness/tones/friendliness, whatever word you want to use. The one voice that doesn't anymore, is the US English female voice. It doesn't say "Brrr" the same way anymore, and it just responds flatly when you ask it to do different taks now, like text someone, email a person, perform a command, etc. If anyone else has noticed this let me know. I'm blind and use Siri every day, I know something is up. Thanks,

Josh
