Fine-tuned Malayalam ASR model based on
openai/whisper-small, trained
as a single-stage baseline using a high learning rate on the full Malayalam
training corpus. This model serves as the High LR baseline (small architecture)
in the
Vividh-ASR: Diagnosing and Fixing Studio-Bias in Whisper for Indic Languages
benchmark suite.
This model is part of a set of Malayalam and Hindi Whisper models released by
Adalat AI alongside the Vividh-ASR benchmark.
The High LR baseline fine-tunes Whisper in a single stage on all available
Malayalam training data mixed together, without any curriculum ordering:
Training uses AdamW (weight decay 0.1), linear warmup for the first 10% of
steps, and cosine annealing to zero. Trained on NVIDIA H100 GPUs using
HuggingFace Transformers.
Benchmark WER is measured using
faster-whisper
with 7s VAD segmentation for long-form audio. See the
blogpost for full evaluation details.
