Modern technology, particularly machine learning, has enabled us to accurately reproduce and even generate sound waves. However, generating clean and intelligible sound from noisy recordings remains a difficult problem. One solution to this problem is through the use of WaveGrad DBlocks which helps downsample the temporal dimension of noisy waveform in WaveGrad.
What are WaveGrad DBlocks?
WaveGrad DBlocks are an algorithmic solution used to generate clean and high-quality sound from noisy recordings. These DBlocks are used in WaveGrad, which is a neural network architecture used for improving the quality of synthetic speech by reconstructing waveform samples with a higher resolution. They help to reduce the noise present in the waveform by down-sampling the temporal dimension.
How Do WaveGrad DBlocks Work?
WaveGrad DBlocks are similar to UBlocks in that they utilize a residual block. However, unlike UBlocks, they only consist of one residual block. The main branch of the WaveGrad DBlocks utilizes dilation factors of 1, 2, and 4, which increases the receptive field size of the network without increasing the number of parameters. Additionally, orthogonal initialization is employed to promote convergence in the training process.
The Benefits of Using WaveGrad DBlocks
By using WaveGrad DBlocks, the architecture is able to remove noise from the waveform while maintaining its temporal resolution. This leads to higher speech quality for synthetic speech synthesizers. Using WaveGrad DBlocks in combination with other modules like WaveGrad Decoder Modules and WaveGrad Encoder Modules enables WaveGrad to produce high-fidelity synthetic speech that is nearly indistinguishable from human speech.
WaveGrad DBlocks are an effective solution for improving the quality of synthetic speech by removing noise from recorded sounds. By utilizing a residual block and employing orthogonal initialization, the WaveGrad DBlocks help to downsample the temporal dimension of the waveform in a way that promotes convergence in the training process. WaveGrad DBlocks are only one part of the WaveGrad architecture, but they play a crucial role in producing high-quality synthesized speech. As technology continues to develop and improve, WaveGrad DBlocks and similar solutions will become even more sophisticated, resulting in more realistic and human-like synthetic speech.
