OmniASR CTC-7B v2, fine-tuned for Shona as part of the WAXAL ASR solution.

Released artifact: three single checkpoints: steps 3563 / 4581 / 5090. Decoded with greedy, then conservative word ROVER across the three checkpoints.

Total weights: 78,071,120,526 bytes (78.07 GB).

Its three checkpoints collapse to one hypothesis by conservative word ROVER, which then enters the 4-family word-medoid MBR.

This model is one component of an ensemble solution and is not intended to be used alone. The routing, decoding, fusion and post-processing pipeline are in the solution repository.

This is a fairseq2 / omnilingual-asr checkpoint, loaded through the asset card shipped alongside it (card.yaml). The solution repository wraps the whole contract -- pinned environment, batch-size-1 decode, tokenizer wiring -- in one CLI:

--weights accepts any directory holding this repo's files, e.g. the path returned by huggingface_hub.snapshot_download("DariusTheGeek/waxal-sna-omniasr-ctc-7b"). requirements.txt in this repo pins the runtime alone; the environment lock the release was verified under is env/requirements-omni.txt in the solution repository.

See https://github.com/DariusTheGeek/waxal-asr-solution for the environment locks, decode configuration and the exact command that reproduces the submission end to end from audio.
