一覽

Whisper is OpenAI's speech recognition model that transcribes audio in 99 languages with high accuracy. Available as open-source model, API, or fine-tuned versions. Used by developers building transcription apps, accessibility tools, meeting recorders, and voice assistants. Specialists integrate Whisper into applications, optimize for latency/cost, and handle edge cases. Salary band: $115–170k mid-level. 3–4 weeks to baseline; 2+ months for production mastery.

什麼是 Whisper Speech Recognition

Whisper is OpenAI's open-source speech recognition model that transcribes audio in 99 languages. It's available as an open-source PyTorch model (self-hosted) or via the OpenAI API. Whisper is robust to accents, background noise, and technical language, outperforming many existing speech recognition systems. Use cases: transcription apps, meeting recordings, accessibility (captions for video), voice commands, and voice-based search. Specialists integrate Whisper into applications, optimize for cost/latency, and handle edge cases (noise, multiple speakers, domain-specific language).

❓ 常見問題

Should I use Whisper API or self-hosted model?
API is easiest (pay per use, no GPU needed). Self-hosted model is cheaper at scale and gives more control. Choose based on volume and latency needs.
What languages does Whisper support?
99 languages. Training data quality varies by language; English and major languages are strongest. Test on your language; quality may vary.
How accurate is Whisper?
Excellent on clear audio (WER ~5-10%). Degrades with background noise, accents, domain-specific jargon. Test on your audio; accuracy depends on audio quality.
Can I fine-tune Whisper?
Yes, the open-source model can be fine-tuned on domain data. API doesn't support fine-tuning yet. Self-hosted fine-tuning requires GPU and ML expertise.
What's the latency for transcription?
API: 5-30s depending on audio length and load. Self-hosted: 2-10s on GPU. Real-time streaming with latency compensation is possible with advanced techniques.
