Implementation of the work presented in "CNN based Query by Example Spoken Term Detection".
We have included some example groundtruth files for training as well as development set.
The posteriors features are extracted using the setup presented in the following paper: "High-performance query-by-example spoken term detection on the SWS 2013 evaluation".
The input feature files for training/evaluation are in pytorch readable format which are saved as python dictionaries. The keys are the names of the files in 'groundtruth files' and values are the features in matrix format.
