Model Details
- Model type: Whisper sequence-to-sequence ASR model
- Base model:
openai/whisper-medium
- Release group: Scaling-law checkpoints
- Checkpoint kind: Single-source supervised fine-tuned checkpoint
- Manuscript role: Scaling-law scripted baseline
- Source artifact:
07_scaling_laws/whisper_medium_train_scrip_bk1
Method Context
This is a single-source fine-tuned checkpoint. In the manuscript it serves as a source model, baseline, or task-vector endpoint for studying how distribution-shift factors can be recombined.
Training/adaptation context: OGI scripted child speech adaptation.
The broader manuscript studies whether speech foundation model adaptations
for different distribution shifts, such as acoustic condition, speaking style,
speaker population, and dialect, can be recombined for low-resource and
intersectional ASR without direct joint-supervision data.
Intended Use
Use this checkpoint to reproduce or extend the paper's ASR model-merging
experiments. It is intended for research on child ASR, compositional domain
adaptation, robustness, cross-corpus transfer, dialectal variation, and scaling
behavior across Whisper model sizes.
How To Load
from transformers import WhisperForConditionalGeneration, WhisperProcessor
model_id = "balaji1312/whisper_medium_sft_ogi_script_0_2"
processor = WhisperProcessor.from_pretrained(model_id)
model = WhisperForConditionalGeneration.from_pretrained(model_id)
For local use before upload:
from pathlib import Path
from transformers import WhisperForConditionalGeneration, WhisperProcessor
model_dir = Path("final_release_models") / "07_scaling_laws" / "whisper_medium_sft_ogi_script_0_2"
processor = WhisperProcessor.from_pretrained(model_dir)
model = WhisperForConditionalGeneration.from_pretrained(model_dir)
Release Files
This model card was generated for the curated release tree. The model-loading
payload consists of:
config.json, generation_config.json, preprocessor_config.json, tokenizer_config.json, tokenizer.json, vocab.json, merges.txt, normalizer.json, special_tokens_map.json, added_tokens.json, model.safetensors
Training state, optimizer state, decode logs, hypotheses, references, and
intermediate experiment outputs were intentionally omitted.
Limitations
The checkpoint is released for research reproducibility. Results outside the
paper's child ASR, robustness, cross-corpus, dialectal, and scaling-law
settings are not characterized here. Reproducing WER numbers requires the
manuscript evaluation pipeline and authorized access to the relevant speech
corpora; no evaluation audio or transcripts are redistributed in this model
folder.
