waxal-lin-mms-1b

MMS-1B native Lingala adapter, fine-tuned for Lingala as part of the WAXAL ASR solution.

Released artifact: top-3 uniform average of steps 1004 / 1506 / 1757. Not decoded in the shipped pipeline — this model embeds voices for TTIA.

Files

Total weights: 3,858,960,487 bytes (3.86 GB).

Role in the pipeline

The TTIA voice embedder: the enrolment gallery and every test clip pass through its encoder, and mean+std-pooled hidden states (layers 4 and 8) drive the idiolect-profile match. It decodes no text in the shipped pipeline.

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.

How to use

# pip install -r requirements.txt   (pinned; see Files)
import librosa, torch
from transformers import AutoProcessor, Wav2Vec2ForCTC

repo = "DariusTheGeek/waxal-lin-mms-1b"
processor = AutoProcessor.from_pretrained(repo)
model = Wav2Vec2ForCTC.from_pretrained(repo).eval().cuda()

audio, _ = librosa.load("clip.wav", sr=16_000, mono=True)
inputs = processor(audio, sampling_rate=16_000, return_tensors="pt")
with torch.no_grad():
    logits = model(inputs.input_values.cuda()).logits
print(processor.batch_decode(logits.argmax(-1))[0])
