Why Transcription Matters

Transcribing audio and video content unlocks multiple benefits: accessibility for deaf viewers, SEO value from searchable text, content repurposing opportunities, and professional documentation.

Manual transcription takes 4-6 hours per hour of audio. AI transcription takes minutes. The accuracy gap has closed dramatically—modern tools achieve 95%+ accuracy on clear audio.
