![]() Special thanks to the following repositories: Example Noisy audio waveformĢ0-Layered Deep Complex U-Net 20 Model Used The noisy, clean and denoised wav files will be saved in the 'Samples' directory. Audio quality metrics will also be calculated. ![]() Point to the testing folders containing the audio you want to denoise. In the 'speech_denoiser_DCUNet.ipynb' file. All of our pre-trained model weights are uploaded in 'Pretrained_Weights' directory under the 'Noise2Noise' and 'Noise2Clean' subdirectories. We have trained our model with both the Noise2Noise and Noise2Clean approaches, for all 10(numbered 0-9) UrbanSound noise classes and White Gaussian noise. Testing Model Inference on Pretrained Weights pth file is saved for each training epoch in the 'Weights' directory. If you are using Linux, set 'sox' as the torchaudio backend. If you are using Windows, set 'soundfile' as the torchaudio backend. You can choose whether to train using our Noise2Noise approach(using noisy audio for both training inputs and targets), or the conventional approach(using noisy audio as training inputs and the clean audio as training target). Specify the type of noise model you want to train to denoise(You have to generate the specific noise Dataset first). The train and test datasets for the specified noise will be generated in the 'Datasets' directory. Python urban_sound_noise_dataset_generator.py We recommend using the Conda package manager to install dependencies. The package versions are in requirements.txt.

We believe that this could significantly advance the prospects of speech denoising technologies for various lowresource languages, due to the decreased costs and barriers in data collection. We aim to incentivise the collection of audioĭata, even when the circumstances are not ideal to allow it to be perfectly clean. This is demonstrated through experiments studying the efficacy of our proposed approach over both real-world noises and synthetic noises using the 20 layered Deep Complex U-Net architecture. Furthermore it is revealed that training regimes using only noisy audio targets achieve superior denoising performance over conventional training regimes utilizing clean training audio targets, in cases involving complex noise distributions and low Signal-to-Noise ratios (high noise environments). This paper removes the obstacle of heavy dependence of clean speech data required by deep learning based audio denoising methods, by showing that it is possible to train deep speech denoising networks using only noisy speech samples.
