  4. Copy the key (starts with sk-...)

Cost

  • $0.006 per minute (~$0.36 per hour)

  1. Run: python audio_transcriber_whisper.py

Tips for Best Accuracy

  • Chunk Duration:

    • 3-5 seconds = faster response, good for conversations
    • 7-10 seconds = better accuracy for long sentences

  • Language Setting:

    • Use auto for mixed languages
    • Set specific language (e.g., bg) for better accuracy in that language

  • Microphone:

    • Use a good quality mic (HyperX, Trust USB)
    • Speak clearly at normal pace
    • Reduce background noise

Supported Languages

English, Bulgarian, Spanish, French, German, Italian, Portuguese, Russian, Japanese, Chinese, Arabic, Turkish, Polish, Ukrainian, and 90+ more!
