Eva gives away her own identity

Here's a description of the contestant's attempt. Someone's probably working on collecting some images to illustrate it.

Eva puts on a pair of sunglasses, and a shirt over her head, to protect her identity. She uses a text-to-speech app on her phone to talk to David without using her own voice, asking him what his job is, but then realises that he is not speaking Danish. She then asks him herself what his name is and, when he answers, accidentally reveals her own name to him. She is therefore disqualified from the task.
