What is Audio Transcription?
Audio transcription is the process of converting spoken words from audio or video files into written text. Modern transcription uses AI-powered speech recognition technology to automatically detect and transcribe speech with high accuracy.
Manual vs Automated Transcription
📝 Manual Transcription
Typing out every word by hand while listening to audio
- ✅ 100% accurate if done carefully
- ❌ Extremely time-consuming (4-6x audio length)
- ❌ Expensive ($1-3 per audio minute)
- ❌ Requires human transcriber
🤖 Automated Transcription
AI software converts speech to text automatically
- ✅ 85-95% accuracy with good audio
- ✅ Fast (same length as audio or faster)
- ✅ Affordable or free
- ✅ Instant results
The verdict: For most use cases, automated transcription is the clear winner. You can always edit the transcript afterwards to fix any errors, which is still much faster than typing from scratch.

7 Tips for Better Transcription Accuracy
1. Use High-Quality Audio
Clear audio is the #1 factor for accuracy. Record in a quiet environment with a good microphone. Avoid wind noise, echo, and background chatter.
2. Speak Clearly and at Normal Pace
Enunciate words properly. Don't rush or mumble. Natural conversational pace works best.
3. Minimize Background Noise
Turn off fans, close windows, silence notifications. Every bit of noise reduction helps.
4. Use Headphones When Playing Audio
When transcribing pre-recorded audio through your microphone, use headphones placed close to the mic for cleaner sound capture.
5. Choose the Correct Language
Always select the right language before starting. AI accuracy drops significantly when the wrong language is selected.
6. Edit After Transcription
No AI is perfect. Budget 10-15 minutes per hour of audio for proofreading and corrections.
7. Upgrade for File Upload
Playing audio through speakers degrades quality. Direct file upload (available in Pro plans) gives significantly better results.
