 Hence, they are of the form `<file-name>|<transcription>/r/n`.
-Luckily this project already comes with a custom loader for the LJ Speech dataset to we do not have to write out own.
-The loader is defined in [datasets/lj_speech.py](datasets/lj_speech.py).
-Based on `metadata.csv` the loader parses the transcriptions and loads the audio files from the `wavs/` folder.
 
 
-## Calculate And Set The Signal Statistics
+## Create Listing Files
 
-Let us now configure the project so that it does use the dataset for training.
-First we will set up the dataset [tacotron/params/dataset.py](tacotron/params/dataset.py).
-Configure the path to the dataset `dataset_folder` and set the `dataset_loader` to be `LJSpeechDatasetHelper`.
-Next, you need to establish an enumerated vocabulary for the dataset and tell the architecture the vocabulary size.

-However, as we do not have this information at hand we will have to collect the, first using [tacotron/dataset_statistics.py](tacotron/dataset_statistics.py).

+## Generate the Dataset Definition File
+
+Before the dataset can be used a definition file has to be created.
+When both `train.csv` and `eval.csv` exist the dataset definition file can be generated like in 
+this:
+```python
+from datasets.dataset import Dataset
+
+dataset = Dataset('/tmp/LJSpeech-1.1/dataset.json')
+dataset.set_dataset_folder('/tmp/LJSpeech-1.1/')
+dataset.set_audio_folder('wavs')
+dataset.set_train_listing_file('train.csv')
+dataset.set_eval_listing_file('eval.csv')
+dataset.load_listings(stale=True)
+dataset.generate_vocabulary()
+
+# Calculates the signal statistics over the entire dataset (may take a while).
+dataset.generate_normalization(n_threads=4)
+dataset.save()
 ```
 
-Now we can complement `vocabulary_dict` and `vocabulary_size` into the dataset configuration in 
-[tacotron/params/dataset.py](tacotron/params/dataset.py).
-Additionally the are given a set of decibel values the loader requires from normalizing features.
-Make sure to set the variables (`mel_mag_ref_db`, `mel_mag_max_db`, `linear_ref_db`, `linear_mag_max_db`) in 
-[datasets/lj_speech.py](datasets/lj_speech.py).
