What are AI Transcription Tools?
AI transcription tools convert spoken audio into written text using speech recognition and natural language processing. They identify speakers, add punctuation, and increasingly understand context. Many offer editing interfaces where you can correct errors while listening to audio.
Why AI Transcription Matters
Audio and video content is everywhere, but text remains essential for searchability, accessibility, and repurposing. Manual transcription is slow and expensive. AI transcription makes it practical to transcribe everything—meetings, podcasts, interviews, lectures—enabling new workflows and use cases.

Frequently Asked Questions
How accurate is AI transcription really?
For clear audio with standard accents, 95%+ accuracy is typical. This means 1-2 errors per 100 words. Strong accents, poor audio, or technical jargon lower accuracy. Human review can achieve 99%+ but costs significantly more.
Can AI transcription handle multiple speakers?
Yes, most tools offer speaker diarization—identifying who said what. Accuracy varies; some tools require naming speakers manually, others identify automatically. Test with your specific use case.
Is AI transcription good enough for legal or medical use?
For reference transcripts, often yes. For official records requiring high accuracy, human review is still recommended. Some industries have specific requirements—check compliance needs.
