OpenAI Whisper
OpenAI — OpenAI's foundational speech recognition and multilingual translation transformer model.
audio-speechv20231117MITqualified
Model Training
This library is a dedicated runtime engine for inference serving and does not train models.
Model Inference
Inference Accelerators:
CPUCUDAROCMMPS
Deployment Targets:server, edge
Quantization:FP16, INT8 (via CTranslate2/faster-whisper)
What It Does
- +Multilingual speech-to-text transcription across 99+ languages with strong zero-shot robustness
- +Direct speech translation from any supported language into English
- +Timestamp generation at segment and word levels
- +Five model size tiers: tiny, base, small, medium, and large-v3
What It Does Not Do
- -Provide ultra-optimized C++ inference out of the box (use faster-whisper or whisper.cpp for 4x speedup)
- -Perform real-time streaming transcription with sub-second latency natively
- -Train from scratch on private data (primarily an inference release)
>Suitable Work Types
- Offline podcast, video, and interview transcription with automatic punctuation
- Translating foreign language conference recordings into English text
- Multilingual subtitle generation with exact word timestamps
>Unsuitable Work Types
- Real-time streaming speech recognition under 200ms latency budgets
- Low-power battery microcontrollers without C++ quantized ports
Data Residency Implications
Runs locally on internal CPU or GPU compute. Zero audio leaves your premises.
Security Considerations
MIT license with permissive commercial rights. Safe for commercial enterprise use.
Operational Profile & Known Limitations
Maturity:mature
Learning Curve:low
Ops Complexity:low
Cost Tier:free-oss
> Known Limitations:
- Vanilla PyTorch implementation in openai/whisper is memory-heavy and slow compared to optimized runtimes like faster-whisper (CTranslate2) or whisper.cpp.
