VoiceOver on the log in screen

HI everyone, For a few weeks now I've had a password set up on my mac, so whenever I would restart my mac or turn it on after it's been shut down, I'd have to enter my password. Usually I'd hear something like, "enter password, VoiceOver will not read the characters" or something like that. As of this morning, it doesn't say that and I have to turn VoiceOver on manually. I'm wondering if I somehow turned off a setting by accident. Hopefully someone in here can help.
