A Quick-Quotes Quill is placed on parchment and will write on its own, leaving the owner free to talk normally.
From the Story
Discovered in Book 4, Chapter 18, The Weighing of the Wands, Moment 2 Rita Skeeter
"Rita Skeeter uses a Quick-Quotes Quill during her interview with Harry at the Wand Weighing ceremony. She tests the Quill by speaking her own name, which results in an account of her appearance and reputation being written down. Before Harry has even spoken, the Quill begins to write about the interview, describing Harry in exaggerated and descriptive language."
