[docs]@dataclass class FastSpeechConfig(BaseTTSConfig): """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.
