Transcription Accuracy
How accurate are transcripts in real use?
SozAI publishes its own accuracy test: on clear read speech, word error rate ran from 1.8% in Spanish to 8.0% in Portuguese. Real-world accuracy depends on audio quality, microphone setup, accents, and background noise. SozAI pairs the transcript with summaries and speaker labels for every user; it has no custom vocabulary yet, so check specialist terms by hand.
Sonix advertises high accuracy on high-quality audio and has a strong reputation among audio/video professionals. Sonix’s accuracy claims are backed by features like word-level timestamps and an editor geared toward fine-grained correction. If you work with studio-grade recordings and demand near-perfect transcripts for publishing, Sonix’s workflow and editor can make post-editing faster. In short: Sonix may reach higher peak accuracy on excellent audio; SozAI is highly competitive for everyday recordings and adds price predictability for frequent users.
