How Long Does It Take to Transcribe an Hour of Audio?

If you have ever tried to transcribe audio files or needed a transcription service, you have likely wondered, “How long does it take to transcribe an hour of audio?” The answer depends on several factors, such as audio quality, the number of speakers, background noise, and whether a human or AI handles the job.

Average Timelines for Transcribing 1 Hour of Audio

Human Transcription

• Industry Standard: Most professional transcriptionists take 3 to 5 hours to fully transcribe 1 hour of clear audio (Source: Transcription Certification Institute, 2023).
• Why the Range?
  • About 3 hours: Straightforward audio with one clear speaker and no background noise.
  • 5 hours or more: Audio involving multiple speakers, heavy accents, or technical terms.

AI (Automated) Transcription

• Speed: Automated tools process an hour of audio within real time or just a few minutes. Some platforms deliver transcripts almost instantly as the audio is recorded.
• Accuracy Needs Editing: Automated results often contain mistakes, especially with background noise or unfamiliar accents, and require proofreading.

Factors That Affect Transcription Time

• Audio Quality:
  • High-quality microphones and quiet recording locations help minimize extra steps.
  • Background noise, such as music or overlapping voices, slows down the process.
• Number of Speakers:
  • Single-speaker audio is easier and quicker.
  • Multiple speakers require speaker identification and labeling, increasing the time needed.
• Accents and Rate of Speech:
  • Unfamiliar accents or fast-talking participants increase difficulty.
  • Human listeners and AI both may need to replay segments to get accurate text.
• Technical or Specialized Language:
  • Medical, legal, or technical terms require additional research.
  • Abbreviations and acronyms must be interpreted or spelled out properly.
• Formatting Needs:
  • Adding timestamps, speaker labels, or special formatting (bullets, paragraphs) requires extra effort.
• Human vs. AI:
  • Human transcription offers higher initial accuracy for challenging audio but takes longer.
  • AI transcription is much faster but needs review and correction.

Breakdown of the Transcription Workflow

1. Listening and Typing:
   • Professional transcribers often replay sections of audio multiple times to confirm every word.
2. Review and Corrections:
   • The first draft is proofread for errors or misheard phrases.
3. Formatting:
   • Applying timestamps, labeling speakers, and structuring text as requested.
4. Quality Control:
   • Experienced editors conduct a final check for accuracy and consistency.
