Instructions for TIMIT prediction experiment

  1. Downsample the TIMIT dataset to 8ksamples/sec using Matlab by running downsample_audio.m from the matlab directory. Make sure you modify the paths in downsample_audio.m for your system.

  2. Download Matlab evaluation code using, which should download and unzip all the required toolboxes to the matlab folder.

  3. Run the experiments using the shell scripts: run_timit_prediction_<model>.sh, which will train the model and score the resulting audio using the Matlab evaluation toolboxes.
