Overview

Whisper Small.en is OpenAI's 244M-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, making it a strong default for English-only workloads that want accuracy without a large footprint. This OpenASR repo repackages the original openai/whisper-small.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.

Highlights

  • 🇬🇧 English-only — specialized for English, typically more accurate on English than the same-size multilingual model
  • 🧠 244M parameters — the small checkpoint balances English accuracy, footprint, and speed
  • 🌐 Weak-supervision scale — trained with Whisper's 680k-hour labelled speech corpus
  • 🦀 Native in OpenASR.oasr packs run with no Python at inference, engineered for CPU and Apple Silicon
