EveryVoice Open Bible — Hiligaynon

A multispeaker text-to-speech model for Hiligaynon, trained from scratch on the Open Bible corpus using the EveryVoice TTS toolkit (FastSpeech2 acoustic model + HiFi-GAN vocoder, 22,050 Hz output).

The model is conditioned on speaker embeddings learned during training. A speaker name from the training set must be supplied at inference time.

Files

File	Purpose
`feature_prediction.ckpt`	Trained FastSpeech2 feature-prediction weights.
`vocoder.ckpt`	HiFi-GAN vocoder checkpoint (optional — can be replaced with a universal vocoder).
`config/`	EveryVoice YAML config files (shared data, text, feature-prediction, spec-to-wav).
`filelist.psv`	Pipe-separated training filelist (`basename

Intended use

Multispeaker TTS for Hiligaynon using one of the training-set speaker voices.
Research on multilingual TTS, low-resource TTS evaluation, and listening studies on Open Bible–style read-speech.

How to use

Install EveryVoice:

pip install everyvoice

Training data

Source: davidguzmanr/open-bible-resources, config Hiligaynon
Size: approximately 18,573 utterances
Speakers: multispeaker; speaker identity is fixed to one of the training-set voices and selected by name at inference time
Sample rate: 22,050 Hz

Training procedure

Acoustic model: FastSpeech2 (non-autoregressive, duration-prediction based).
Vocoder: HiFi-GAN (iSTFT variant).
Character-level tokenizer built from the training transcripts.
Trained with the EveryVoice toolkit.

Audio preprocessing and training are reproducible via the upstream open-bible-models repo.

Evaluation

Evaluated alongside other Open-Bible TTS systems on character/word error rate (via Meta's Omnilingual ASR) and UTMOSv2 naturalness scores. See the open-bible-models repository for the evaluation pipeline and the open-bible-surveys repository for the human-listening survey methodology.
