Whisper small.en — Gumbel-BEARD

This is an openai/whisper-small.en model whose encoder was domain-adapted with Gumbel-BEARD — a self-supervised continued-pretraining recipe — and then fine-tuned for automatic speech recognition (ASR) on the MyST children's speech corpus.

On the MyST test set it achieves 8.5% WER.

• Base model: openai/whisper-small.en
• Task: English automatic speech recognition
• Adaptation: self-supervised (transcript-free) encoder adaptation via Gumbel-BEARD, followed by supervised ASR fine-tuning
• Code: <your-github-repo-url>

Usage

from transformers import pipeline

asr = pipeline(
    "automatic-speech-recognition",
    model="Zilai2999/whisper-small.en-gumbel-beard",
)
print(asr("audio.wav")["text"])

Or with the model/processor directly:

import torch, librosa
from transformers import WhisperForConditionalGeneration, WhisperProcessor

model_id = "Zilai2999/whisper-small.en-gumbel-beard"
processor = WhisperProcessor.from_pretrained(model_id)
model = WhisperForConditionalGeneration.from_pretrained(model_id)

audio, _ = librosa.load("audio.wav", sr=16000)
inputs = processor(audio, sampling_rate=16000, return_tensors="pt")
ids = model.generate(inputs.input_features)
print(processor.batch_decode(ids, skip_special_tokens=True)[0])

Audio is expected at 16 kHz.

Training

• Self-supervised Gumbel-BEARD adaptation of the Whisper encoder (BEST-RQ + self-distillation with automatic Gumbel-softmax layer selection).
• Supervised ASR fine-tuning on the MyST children's speech corpus.

See the code repository for the full recipe and hyper-parameters.
