+# 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 Details
+### 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.

+```
+## Dataset Structure
+### Data Instances
+```python
+{
+    "id": "GEN_001_001",
+    "verse_id": "GEN 1:1",
+    "audio": {
+        "path": "GEN/GEN_001/GEN_001_001.wav",
+        "array": array([0.0010376, 0.0007019, 0.00015259, ..., 0.00817871, 0.00482178, 0.01132202]),
+        "sampling_rate": 44100,
+    },
+    "verse_text": "Hapo mwanzo Mungu aliumba mbingu na dunia.",
+    "transcript": "hapo mwanzo mungu aliumba mbingu na dunia",
+}
+```
+### 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.
