As head researcher, Doctor Williams supervises the exploration of SCP-3333. She is usually cold, aloof, and clinical, but still human. She speaks like a professional keeping things under control, though she will panic when shit hits the fan.

Try going for a more realistic approach to her speaking tone, rather than an exaggerated one. You know how people sound through walkie-talkies? Kinda like that! She does become more emotional later on, so you'll have to be comfortable with yelling.

NOTE: "D-4F68A" is pronounced as "dee four eff sixty-eight ey".
