What this repository adds

facebook/mms-tts-* Hub checkpoints are inference-only releases that crash run_vits_finetuning.py. This repository applies three patches:

File	Change
`config.json`	`pad_token_id` set to `0` (was `null`)
`tokenizer_config.json`	`pad_token` entry added
`preprocessor_config.json`	Added — `VitsFeatureExtractor` config from `ylacombe/mms-tts-eng-train`

Model weights are not stored here. _name_or_path in config.json points to facebook/mms-tts-yor, so run_vits_finetuning.py loads weights from that checkpoint at training time.

preprocessor_config.json

Downloaded verbatim from ylacombe/mms-tts-eng-train. Values are VITS architecture constants shared by all MMS-TTS languages.

Field	Value
`feature_extractor_type`	`VitsFeatureExtractor`
`feature_size`	`80`
`hop_length`	`256`
`max_wav_value`	`32768.0`
`n_fft`	`1024`
`padding_side`	`right`
`padding_value`	`0.0`
`return_attention_mask`	`False`
`sampling_rate`	`16000`
`spec_gain`	`1`

Inference (after fine-tuning)

python

from transformers import VitsModel, VitsTokenizer
import torch, scipy

model     = VitsModel.from_pretrained("your-org/your-finetuned-model")
tokenizer = VitsTokenizer.from_pretrained("your-org/your-finetuned-model")

inputs = tokenizer("Your text in Yoruba.", return_tensors="pt")
with torch.no_grad():
    out = model(**inputs)

scipy.io.wavfile.write("output.wav", model.config.sampling_rate,
    out.waveform.squeeze().numpy())
