Compact English-only Whisper for fast English transcription
Whisper Base.en is OpenAI's 74M-parameter English-only Whisper checkpoint. It uses the standard
Whisper encoder-decoder architecture for automatic speech recognition, trained with large-scale
weak supervision on 680k hours of labelled speech. As an English-specialized model it tends to
outperform the same-size multilingual Whisper on English audio, while staying small and fast.
This OpenASR repo repackages the original openai/whisper-base.en weights as .oasr packs that
run natively in the OpenASR runtime with no Python at inference time. For most users the q8_0
build is the recommended default; q4_k is for tighter memory budgets and fp16 is for
verification or maximum fidelity.
.oasr packs run with no Python at inference, engineered for CPU and Apple SiliconThese are CLI / local-server examples. The desktop app runs this model without typing a command — see the desktop install path above.
