 M4T training dataset is a multimodal parallel corpus. Each training sample has four parts: audio and text representation of the sample in the source language, and its corresponding audio and text representation in the target language.
 
-That kind of dataset can be prepared using `dataset.py` script that downloads FLEURS dataset from [HuggingFace datastes hub](https://huggingface.co/datasets/google/fleurs), (optionally) extracts units from the target audio samples, and prepares a manifest consumable by `finetune.py`. Manifest is a text file where each line represents information about a single dataset sample, serialized in JSON format.
