AvaSanj-v1
Persian repr1 automatic speech recognizer (AvaSanj v1) fine-tuned from
facebook/wav2vec2-xls-r-300m on 8,437 approved Persian audio clips.
Outputs phonemes in the shared repr1 alphabet (A C Q S Z … + lowercase IPA-style phonemes) — the
same canonical alphabet used by the Negara G2P models, making this model a drop-in listener for
grapheme-to-phoneme adjudication.
Provenance
- Original model:
facebook/wav2vec2-xls-r-300m(Apache-2.0), fine-tuned for CTC. - Data: 8,437 approved (lattice-supported) Persian clips; target labels are the
audio_target_phonemes_vnextrepr1 label field. - Role: used as the OOF (out-of-fold) listener in the AvaSanj data pipeline — each fold scores only
voices it never trained on — to arbitrate G2P disagreements at margin
≥ 0.1(~96.3% precision / 95.9% recall on the corruption gate). - Selection: best step 800, best validation CER 0.0479.
Model
- Architecture: Wav2Vec2ForCTC, base
wav2vec2-xls-r-300m(~300 M params). - Vocabulary: repr1 (see
vocabulary.json) — 30-token inventory incl.<blank>+" ". - Full eval:
report.json.
Usage
from transformers import Wav2Vec2ForCTC
model = Wav2Vec2ForCTC.from_pretrained("Reza2kn/AvaSanj-v1-audio8437")
Note: load with the local vocabulary.json for the repr1 tokenizer mapping.
