Method 1: Whisper (Best Free Option, Unlimited)

OpenAI’s Whisper is open-source and runs locally on your computer — meaning unlimited free transcription with no file uploads required.

Quick Setup

1. Install Python 3.8+ if not already installed
2. Run: pip install openai-whisper
3. Transcribe: whisper audio.mp3 --model medium --language en

The “medium” model offers the best balance of speed and accuracy. Use “large” for maximum accuracy on difficult audio. Whisper outputs text, SRT subtitles, and VTT files.

Method 2: Otter.ai (Best for Meetings)

Otter.ai excels at live meeting transcription. The free tier gives you 300 minutes per month with automatic speaker identification. It integrates with Zoom, Google Meet, and Microsoft Teams to join and transcribe meetings automatically.

Method 3: TurboScribe (Best for Quick Files)

Upload up to 3 audio/video files per day for free. TurboScribe uses Whisper technology with a clean web interface — no installation required. Supports files up to 300MB.

Tips for Better Transcription Accuracy

• Use a quality microphone — USB mics dramatically improve accuracy over laptop mics
• Minimize background noise — close windows, turn off fans, use a quiet room
• Speak clearly — natural pace, avoid mumbling
• Use the right model size — larger models are slower but more accurate for difficult audio
• Specify the language — auto-detection works but explicit language setting is more reliable

Common Use Cases

• Meeting notes — Otter.ai for live transcription with action items
• Podcast show notes — Descript for transcription + editing
• Lecture notes — Whisper for offline processing of long recordings
• Interview transcription — TurboScribe for quick file uploads
• YouTube subtitles — Whisper outputs SRT files ready for upload
• Content repurposing — Transcribe videos to create blog posts and social content

Transcription Editing Tips

Even at 95% accuracy, you’ll need to review transcripts for:

• Proper nouns and industry jargon
• Numbers and dates
• Speaker attribution in multi-person recordings
• Punctuation and paragraph breaks

Use ChatGPT to clean up raw transcripts: “Clean up this transcript, fix obvious errors, add proper punctuation, and format into paragraphs. Keep the original meaning: [paste transcript]”
