Tensorflow Wavenet
This project is a TensorFlow implementation of a neural network for raw audio waveform generation. It functions as a conditioned speech synthesis model that produces synthetic audio samples using a dilated convolutional neural network architecture.
The system supports custom voice modeling by incorporating global conditioning and categorical identifiers during training and generation. This allows the model to mimic specific speakers or distinct audio characteristics for neural text-to-speech applications.
The framework covers deep learning audio synthesis, including audio dataset processing, model training from waveform files, and the generation of playable audio files. It utilizes technical components such as dilated causal convolutions, mu-law companding, and quantized softmax outputs to handle long-range dependencies in audio data.
