Dataset Card for OpenBible Swahili

OpenBible Swahili is a verse-level segmented audio of Swahili: Biblica® Open Kiswahili Contemporary Version (Neno). This dataset/project is inspired by masakhane-io/bibleTTS and coqui-ai/open-bible-scripts, with a twist of applying the more recent Massively Multilingual Speech (MMS) for audio alignment.

Dataset Details

Dataset Description

For a more detailed description, please refer to OpenBible-TTS.

We followed the CTC Forced Alignment API Tutorial graciously provided by PyTorch. We used the Massively Multilingual Speech (MMS) 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 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, 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.
