Frequently asked questions
What accuracy level can I expect from AI subtitle generators?
Leading AI tools like Rev and Google Cloud Speech-to-Text achieve 95-99% accuracy on clean audio with standard accents. Accuracy drops with background noise, multiple speakers, or strong accents. Professional tools offer human review for broadcast-quality; social media tools prioritise speed over perfect accuracy.
How much do these tools cost for video creators on a budget?
Free options include CapCut, Subtitle Edit, and free tiers from Kapwing and Opus Clip. Paid subscriptions start from £5 per month for Subly or Kapwing. Pay-per-minute services like Rev start at £1.25/minute, scaling with usage volume.
Which tool works best for long-form content like podcasts?
Sonix, Descript, and Rev excel at long-form content with fast turnaround and robust editing. Google Cloud Speech-to-Text is ideal for enterprise podcasts needing custom integration. CapCut and Kapwing work better for short-form social media clips.
