Please see project website for the overview.

Code migrated to run on TensorFlow 1.4 and modified to add inference using sample audio file.

Basic Intructions:

Training

To train the network, simply run python2 run.py --save_dir SAVE_DIR
Where SAVE_DIR is the directory under ./save/ which the network will be saved.

Inference

For inference, the following steps must be taken:

  • Install FFMPEG. On Ubuntu it would be sudo apt-get install ffmpeg
  • Install FFMPEG-Normalize. If you have PIP, you can use pip install ffmpeg-normalize , else refer to the sourcecode page on Github
  • Put your recorded .wav file in the root of the source directory
  • Run preprocess.py using python2 preprocess.py INPUTFILE OUTPUTFILE where INPUTFILE is the input .wav file and OUTPUTFILE is the name you want for your output file. (Note: This preprocess is different than the ones used in run.py and util.py)
  • Copy the resulting OUTPUTFILE.npy to ./obama_data/audio/normalized-cep13/
  • Run the inference network using python2 run.py --save_dir SAVE_DIR --input2 OUTPUTFILE
  • The result should appear in ./results/ directory.

(The above steps can be automated in a script of course.)
