"""Configure `ForwardTTS` as FastSpeech model.
|
|
|
|
Example:
|
|
|
|
>>> from TTS.tts.configs.fast_speech_config import FastSpeechConfig
|
|
>>> config = FastSpeechConfig()
|
|
|
|
Args:
|
|
model (str):
|
|
Model name used for selecting the right model at initialization. Defaults to `fast_pitch`.
|
|
|
|
base_model (str):
|
|
Name of the base model being configured as this model so that 🐸 TTS knows it needs to initiate
|
|
the base model rather than searching for the `model` implementation. Defaults to `forward_tts`.
|
|
|
|
model_args (Coqpit):
|
|
Model class arguments. Check `FastSpeechArgs` for more details. Defaults to `FastSpeechArgs()`.
|
|
|
|
data_dep_init_steps (int):
|
|
Number of steps used for computing normalization parameters at the beginning of the training. GlowTTS uses
|
|
Activation Normalization that pre-computes normalization stats at the beginning and use the same values
|
|
for the rest. Defaults to 10.
|
|
|
|
speakers_file (str):
|
|
Path to the file containing the list of speakers. Needed at inference for loading matching speaker ids to
|
|
speaker names. Defaults to `None`.
|
|
|
|
|
|
use_speaker_embedding (bool):
|
|
enable / disable using speaker embeddings for multi-speaker models. If set True, the model is
|
|
in the multi-speaker mode. Defaults to False.
|
|
|
|
use_d_vector_file (bool):
|
|
enable /disable using external speaker embeddings in place of the learned embeddings. Defaults to False.
|
|
|
|
d_vector_file (str):
|
|
Path to the file including pre-computed speaker embeddings. Defaults to None.
|
|
|
|
d_vector_dim (int):
|
|
Dimension of the external speaker embeddings. Defaults to 0.
|
|
|
|
optimizer (str):
|
|
Name of the model optimizer. Defaults to `Adam`.
|
|
|
|
optimizer_params (dict):
|
|
Arguments of the model optimizer. Defaults to `{"betas": [0.9, 0.998], "weight_decay": 1e-6}`.
|
|
|
|
lr_scheduler (str):
|
|
Name of the learning rate scheduler. Defaults to `Noam`.
|
|
|
|
lr_scheduler_params (dict):
|
|
Arguments of the learning rate scheduler. Defaults to `{"warmup_steps": 4000}`.
|
|
|
|
lr (float):
|
|
Initial learning rate. Defaults to `1e-3`.
|
|
|
|
grad_clip (float):
|
|
Gradient norm clipping value. Defaults to `5.0`.
|
|
|
|
spec_loss_type (str):
|
|
Type of the spectrogram loss. Check `ForwardTTSLoss` for possible values. Defaults to `mse`.
|
|
|
|
duration_loss_type (str):
|
|
Type of the duration loss. Check `ForwardTTSLoss` for possible values. Defaults to `mse`.
|
|
|
|
use_ssim_loss (bool):
|
|
Enable/disable the use of SSIM (Structural Similarity) loss. Defaults to True.
|
|
|
|
wd (float):
|
|
Weight decay coefficient. Defaults to `1e-7`.
|
|
|
|
ssim_loss_alpha (float):
|
|
Weight for the SSIM loss. If set 0, disables the SSIM loss. Defaults to 1.0.
|
|
|
|
dur_loss_alpha (float):
|
|
Weight for the duration predictor's loss. If set 0, disables the huber loss. Defaults to 1.0.
|
|
|
|
spec_loss_alpha (float):
|
|
Weight for the L1 spectrogram loss. If set 0, disables the L1 loss. Defaults to 1.0.
|
|
|
|
pitch_loss_alpha (float):
|
|
Weight for the pitch predictor's loss. If set 0, disables the pitch predictor. Defaults to 1.0.
|
|
|
|
binary_loss_alpha (float):
|
|
Weight for the binary loss. If set 0, disables the binary loss. Defaults to 1.0.
|
|
|
|
binary_loss_warmup_epochs (float):
|
|
Number of epochs to gradually increase the binary loss impact. Defaults to 150.
|
|
|
|
min_seq_len (int):
|
|
Minimum input sequence length to be used at training.
|
|
|
|
max_seq_len (int):
|
|
Maximum input sequence length to be used at training. Larger values result in more VRAM usage.
