# Dataset Card for OpenBible Swahili |
|
|
|
OpenBible Swahili is a verse-level segmented audio of [Swahili: Biblica® Open Kiswahili Contemporary Version (Neno)](https://open.bible/bibles/swahili-biblica-audio-bible/). This dataset/project is inspired by [masakhane-io/bibleTTS](https://github.com/masakhane-io/bibleTTS) and [coqui-ai/open-bible-scripts](https://github.com/coqui-ai/open-bible-scripts), with a twist of applying the more recent [Massively Multilingual Speech (MMS)](https://arxiv.org/abs/2305.13516) for audio alignment. |

### Dataset Description |
|
|
|
> For a more detailed description, please refer to [OpenBible-TTS](https://github.com/bookbot-hive/OpenBible-TTS/tree/main). |
|
|
|
We followed the [CTC Forced Alignment API Tutorial](https://pytorch.org/audio/main/tutorials/ctc_forced_alignment_api_tutorial.html) graciously provided by PyTorch. We used the [Massively Multilingual Speech (MMS)](https://arxiv.org/abs/2305.13516) model to align the audio to the text. |
|
|
|
Like the challenges explained in the MMS paper, we also faced the same noisy audio alignment issues: |
|
|
|
- Chapter introduction narration |
|
- Occasional verse number reading |
|
- Digits/number handling |
|
|
|
While [masakhane-io/bibleTTS](https://github.com/masakhane-io/bibleTTS) proposes a solution by manually (1) inserting chapter introduction transcript and (2) spells out numbers, we decided to use a mix of MMS' method by (1) inserting `*` token for additional speech (e.g. chapter introduction, verse number reading) and (2) converting digits to words using [num2words](https://github.com/rhasspy/num2words), if available. |
|
|
|
The aligned verse text and audio are then segmented into verse-level segments for TTS model training. We recommend reading the MMS paper for better understanding. |

``` |
|
|
|
### Data Fields |
|
|
|
- `id`: a unique identifier for the verse, formatted as `BOOK_CHAPTER_VERSE`. |
|
- `verse_id`: the verse identifier, formatted as `BOOK CHAPTER:VERSE`. |
|
- `audio`: a dictionary containing the path to the audio file, the decoded audio array, and the sampling rate. |
|
- `path`: the path to the audio file. |
|
- `array`: the decoded audio array. |
|
- `sampling_rate`: the sampling rate of the audio. |
|
- `verse_text`: the verse text, with proper capitalization and punctuations. |
|
- `transcript`: the lowercased, punctuation-removed version of `verse_text`, used during forced-alignment. |
