This is the elicitation paragraph used by Steven Weinberger's Speech Accent Archive at George Mason University. This recording was read by Quinn, an 8 year old boy who lives outside Philadelphia, Pennsylvania, USA.
The paragraph is:
Please call Stella. Ask her to bring these things with her from the store: Six spoons of fresh snow peas, five thick slabs of blue cheese, and maybe a snack for her brother Bob. We also need a small plastic snake and a big toy frog for the kids. She can scoop these things into three red bags, and we will go meet her Wednesday at the train station.
