This directory (sitw) contains example scripts for the Speakers in the Wild (SITW) Speaker Recognition Challenge. The SITW corpus is required, and can be obtained by following the directions at the url http://www.speech.sri.com/projects/sitw/ Additional data sources (e.g., VoxCeleb and MUSAN) are required to train the systems in the subdirectories. See the corresponding README.txt files in the subdirectories for more details. Note: This recipe requires ffmpeg to be installed and its location included in $PATH. The subdirectories "v1" and so on are different speaker recognition recipes. The recipe in v1 is a traditional i-vector system while the v2 recipe uses DNN embeddings called x-vectors.
