Whether you’re a student, podcaster, journalist, or researcher, transcription can be a time-consuming task. One of the most common questions people ask is: How long does it really take to transcribe 1 hour of audio? The answer varies depending on whether you’re using AI transcription tools or typing manually, and on several other factors like ljudkvalitet, accents, and the number of speakers.
Om du vill get your transcript quickly, AI tools like VOMO are the best choice, delivering results in just a few minutes.
Average Transcription Time
| Audio Length | Average Person | Professional Transcriber | AI-transkription Verktyg |
|---|---|---|---|
| 15 minutes | 1–1.5 hours | 30–60 minutes | A few seconds – 1 minute |
| 30 minuter | 2–3 hours | 1–2 hours | 1–2 minutes |
| 1 hour | Around 4 hours | 2–3 hours | A few seconds – a few minutes |
👉 Kort sagt..: Manually transcribing 1 hour of audio usually takes 3–4 hours, while AI tools can do it in seconds or minutes.
Category A vs. Category B Audio
The difficulty of transcription heavily depends on audio quality and speaking conditions. In the industry, audio is often classified as Category A or Category B:
| Category | Audio Characteristics | Exempel |
|---|---|---|
| ✅ Category A (Easy) | Clear audio, 1–2 speakers, little to no background noise, minimal technical terms | Interviews, speeches, lectures |
| ⚠️ Category B (Difficult) | Background noise, overlapping speakers, strong accents, technical vocabulary | Court recordings, meetings, conferences, hospital recordings |
📌 Category A audio is the fastest to transcribe, medan Category B can double or even triple transcription time.
What Affects Transcription Time?
| Faktor | Why It Slows Down Transcription |
|---|---|
| 🎙 Poor audio quality | Noise or echo makes it necessary to replay audio repeatedly |
| 🗣 Flera högtalare | Overlapping conversations and speaker identification take more time |
| 🌍 Strong accents | Non-native or strong regional accents require more listening effort |
| 📚 Technical vocabulary | Legal, medical, or scientific terms need research and verification |
| ⌨️ Typing speed & tools | Without transcription software, foot pedals, or shortcuts, productivity drops |
Artificial vs. AI Transcription — Which Is Better?
| Comparison | Manuell transkribering | AI Transcription (Vomo, Whisper, Otter.ai) |
|---|---|---|
| Hastighet | Slow | Seconds to minutes |
| Noggrannhet | High (depends on skill) | 85–95%, varies by audio quality |
| Flerspråkigt stöd | Requires knowledge | Supports multiple languages automatically |
| Auto Summaries | ❌ Nej | ✅ Yes—can generate summaries, keywords, subtitles |
| Kostnad | High time/labor cost | Often free or low-cost |
How to Speed Up Transcription
✔ Use professional AI tools like Vomo, Whisper, Otter.ai, or Notta
✔ Clean audio beforehand: reduce noise, trim unnecessary parts
✔ Use subtitle tools or auto-text syncing features
✔ For complex content (medical or legal), use AI transcription + human proofreading for accuracy
