The standard deviation of the truncated_normal_initializer for initializing all weight matrices.
|
|
leaky_relu_slope (`float`, *optional*, defaults to 0.1):
|
|
The angle of the negative slope used by the leaky ReLU activation.
|
|
normalize_before (`bool`, *optional*, defaults to `True`):
|
|
Whether or not to normalize the spectrogram before vocoding using the vocoder's learned mean and variance.
|
|
|
|
Example:
|
|
|
|
```python
|
|
>>> from transformers import SpeechT5HifiGan, SpeechT5HifiGanConfig
|
|
|
|
>>> # Initializing a "microsoft/speecht5_hifigan" style configuration
|
|
>>> configuration = SpeechT5HifiGanConfig()
|
|
|
|
>>> # Initializing a model (with random weights) from the "microsoft/speecht5_hifigan" style configuration
|
|
>>> model = SpeechT5HifiGan(configuration)
|
|
|
|
>>> # Accessing the model configuration
|
|
>>> configuration = model.config
