This template serves as a starting point for contributing a dataset to the Nusantara Dataset repo.

When modifying it for your dataset, look for TODO items that offer specific instructions.

Full documentation on writing dataset loading scripts can be found here:

https://huggingface.co/docs/datasets/add_dataset.html

To create a dataset loading script you will create a class and implement 3 methods:

  * `_info`: Establishes the schema for the dataset, and returns a datasets.DatasetInfo object.

  * `_split_generators`: Downloads and extracts data for each split (e.g. train/val/test) or associate local data with each split.

  * `_generate_examples`: Creates examples from data on disk that conform to each schema defined in `_info`.

TODO: Before submitting your script, delete this doc string and replace it with a description of your dataset.

    CVSS is a dataset on speech-to-speech translation. The data available are Indonesian audio files

    and their English transcriptions. There are two versions of the datasets, both derived from CoVoST 2,

    with each version providing unique values:

    CVSS-C: All the translation speeches are in a single canonical speaker's voice. Despite being synthetic, these

    speeches are of very high naturalness and cleanness, as well as having a consistent speaking style. These properties

    ease the modeling of the target speech and enable models to produce high quality translation speech suitable for

    user-facing applications.

    CVSS-T: The translation speeches are in voices transferred from the corresponding source speeches. Each translation

    pair has similar voices on the two sides despite being in different languages, making this dataset suitable for building models that preserve speakers' voices when translating speech into different languages.

    Together with the source speeches originated from Common Voice, they make two multilingual speech-to-speech

    translation datasets each with about 1,900 hours of speech.

    In addition to translation speech, CVSS also provides normalized translation text matching the pronunciation in the translation speech (e.g. on numbers, currencies, acronyms, etc.), which can be used for both model training as well as standardizing evaluation.
