Preguntas frecuentes
How accurate is Whisper Large v3?
Whisper Large v3 has a word error rate (WER) comparable to paid cloud services. It reaches very high quality in clear recordings. For medical or legal transcription, always review the output manually.
Do I need a GPU for Whisper?
Not necessarily. With whisper.cpp you can transcribe on CPU with reasonable results. A GPU speeds up processing by 5x–20x. For long files (hours of audio), the GPU makes a significant difference.
Does Whisper support multiple languages?
Yes. Whisper was trained on 99 languages and has excellent multilingual support. Add `--language en` (or the appropriate code) to the command to force the language and improve accuracy.
