Hubby and I did voice recordings and a survey for an NPR experiment on voice crunching. Basically they want to see how well technology does in understanding English speakers of various backgrounds. It was fun! There was a portion where you pick one of two listed topics to talk about freely. Then you read a long list of sentences. If anyone else is interested in contributing to such a experiment, you can read about it on NPR's (National Public Radio's) website at NPR Choice page
