(1) Test-Driven Speech Corpus Development; and (2) Gunshot Detection

Mark Hasegawa-Johnson, 9/20/2013, 2-3pm, BI 2369

This talk will discuss two very different topics. First, I'll introduce the idea of test-driven speech corpus development. I'll describe and demonstrate the tool I created for this purpose, the SProSIG corpus tool. Second, I'll talk about a project in gunshot detection. I will describe three methods that were used in the attempt to detect gunshots in rock music backgrounds (e.g., in advertisements and film scores). It turns out to be a pretty hard problem; all three methods got 99\% correct classification on isolated gunshots vs. other audio, but only the peak-detection method worked reasonably well in real mixtures.
