+    """Configure `ForwardTTS` as FastPitch model.
+
+    Example:

+        >>> config = FastPitchConfig()
+
+    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 `FastPitchArgs` for more details. Defaults to `FastPitchArgs()`.
+
+        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`.

+            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_align_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.
+
+        # dataset configs
+        compute_f0(bool):
+            Compute pitch. defaults to True
