AI Transcription Engine and Accuracy
Happy Scribe's AI transcription supports 120+ languages and typically processes files in minutes. On clean audio with one or two distinct speakers, accuracy reaches 90-95% in major languages like English, Spanish, French, and German. The engine handles standard accents well and automatically adds punctuation, paragraph breaks, and speaker labels. Where it struggles: noisy backgrounds, overlapping speakers, heavy accents, and niche technical vocabulary all reduce accuracy significantly. Most creators report spending 20-40% of the original recording length on cleanup for AI transcripts. The custom vocabulary feature helps -- add your recurring names, brand terms, and jargon -- but it will not fix fundamentally noisy audio. If your recording setup is inconsistent, budget extra time for editing or consider the human transcription add-on for critical episodes.
