Ahoprocessing tools (ahoproc_tools) is also needed, and the public repo is found here.
Latest denoising audio samples with baselines can be found in the segan+ samples website. SEGAN is the vanilla SEGAN version (like the one in TensorFlow repo), whereas SEGAN+ is the shallower improved version included as default parameters of this repo.
The voicing/dewhispering audio samples can be found in the whispersegan samples website. Artifacts can now be palliated a bit more with --interf_pair fake signals, more data than the one we had available (just 20 mins with 1 speaker per model) and longer training session by iterating more than 100 epoch.
SEGAN+ generator weights are released and can be downloaded in this link. Make sure you place this file into the ckpt_segan+ directory to make it work with the proper train.opts config file within that folder. The script run_segan+_clean.sh will properly read the ckpt in that directory as it is configured to be used with this referenced file.
Two models are ready to train and use to make wav2wav speech enhancement conversions. SEGAN+ is an improved version of SEGAN [1], denoising utterances with its generator network (G).
To train this model, the following command should be ran:
python train.py --save_path ckpt_segan+ --batch_size 300 \
--clean_trainset data/clean_trainset \
--noisy_trainset data/noisy_trainset \
--cache_dir data/cache
Read run_segan+_train.sh for more guidance. This will use the default parameters to structure both G and D, but they can be tunned with many options. For example, one can play with --d_pretrained_ckpt and/or --g_pretrained_ckpt to specify a departure pre-train checkpoint to fine-tune some characteristics of our enhancement system, like language, as in [2].
Cleaning files is done by specifying the generator weights checkpoint, its config file from training and appropriate paths for input and output files (Use soundfile wav writer backend (recommended) specifying the --soundfile flag):
python clean.py --g_pretrained_ckpt ckpt_segan+/<weights_ckpt_for_G> \
--cfg_file ckpt_segan+/train.opts --synthesis_path enhanced_results \
--test_files data/noisy_testset --soundfile
Read run_segan+_clean.sh for more guidance.
There is a WSEGAN, which stands for the dewhispering SEGAN [3]. This system is activated (rather than vanilla SEGAN) by specifying the --wsegan flag. Additionally, the --misalign_pair flag will add another fake pair to the adversarial loss indicating that content changes between input and output of G is bad, something that improved our results for [3].

- Multi-GPU is not supported yet in this framework.
- Virtual Batch Norm is not included as in the very first SEGAN code, as similar results to those of original paper can be obtained with regular BatchNorm in D (ONLY D).
