+ # Dataset Card for OpenBible Swahili
12
+
13
+ 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.

17
+ ### Dataset Description
18
+
19
+ > For a more detailed description, please refer to [OpenBible-TTS](https://github.com/bookbot-hive/OpenBible-TTS/tree/main).
20
+
21
+ 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.
22
+
23
+ Like the challenges explained in the MMS paper, we also faced the same noisy audio alignment issues:
24
+
25
+ - Chapter introduction narration
26
+ - Occasional verse number reading
27
+ - Digits/number handling
28
+
29
+ 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.
30
+
31
+ 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
49
+
50
+ ### Data Instances
51
+
52
+ ```python
53
+ {
54
+ "id": "GEN_001_001",
55
+ "verse_id": "GEN 1:1",
56
+ "audio": {
57
+ "path": "GEN/GEN_001/GEN_001_001.wav",
58
+ "array": array([0.0010376, 0.0007019, 0.00015259, ..., 0.00817871, 0.00482178, 0.01132202]),
59
+ "sampling_rate": 44100,
60
+ },
61
+ "verse_text": "Hapo mwanzo Mungu aliumba mbingu na dunia.",
62
+ "transcript": "hapo mwanzo mungu aliumba mbingu na dunia",
63
+ }
64
+ ```
65
+
66
+ ### Data Fields
67
+
68
+ - `id`: a unique identifier for the verse, formatted as `BOOK_CHAPTER_VERSE`.
69
+ - `verse_id`: the verse identifier, formatted as `BOOK CHAPTER:VERSE`.
70
+ - `audio`: a dictionary containing the path to the audio file, the decoded audio array, and the sampling rate.
71
+ - `path`: the path to the audio file.
72
+ - `array`: the decoded audio array.
73
+ - `sampling_rate`: the sampling rate of the audio.
74
+ - `verse_text`: the verse text, with proper capitalization and punctuations.
75
+ - `transcript`: the lowercased, punctuation-removed version of `verse_text`, used during forced-alignment.
