Speech Separation with uPIT

Speech separation with utterance-level PIT(Permutation Invariant Training)

Requirements

see requirements.txt

Usage

1. Generate dataset using create-speaker-mixtures.zip

2. Prepare cmvn, .scp and configure experiments in .yaml files

3. Training:

   ./run_pit.py --config $conf --num-epoches 100 > $checkpoint/train.log 2>&1 &
   

4. Inference:

   ./separate.py --dump-dir cache $mdl_dir/train.yaml $mdl_dir/epoch.40.pkl egs.scp
