I have to get into the college for the main quest, but I have no magical ability on this character so to get her to let me in I told her I was the Dragonborn. She told me to show her the voice. I keep shouting, but she just keeps telling me the same thing over and over, I can't even talk to her, she just keeps telling me to shout when I select her.
Something worth noting is that she's not in her normal spot. When I started talking to her she was, but as soon as she asked me to shout and the conversation ended, she ran to the inn and went inside. Now she's standing in the inn next to the door just telling me to shout over and over again.

I found out what was happening. I have the When Vampires Attack mod installed, which makes citizens run inside during a vampire attack. A vampire just happened to spawn in town during my conversation with Faralda, so as soon as the conversation ended, she ran inside the nearest public building (the inn). That's why two other people were also standing near the door. As soon as I left the inn and killed the vampire Faralda went back to her spot. Once she got there a simple 'Fus' aimed at the sky made her take me to the College.
