How accurate is AI speech transcription for captions?
AI captions need a full review against the spoken audio. Check every line, especially names, numbers, overlapping speech and quiet sections.

AI caption accuracy depends on the recording and the words being spoken. Review the complete captioned video against its audio before posting. Names, numbers, quiet speech and overlapping speakers deserve particular attention. A correctly spelled caption also needs to appear at the right moment.
There is no useful shortcut in checking only the opening. A wrong product name halfway through the video matters even when the first few captions are right.
Check the words and timing separately
| Check | What to look for |
|---|---|
| Exact wording | Missing words, substitutions or repeated phrases |
| Names and numbers | Spelling, dates, prices and quantities |
| Speaker changes | Text that combines two people talking |
| Quiet sections | Captions where nobody is speaking |
| Timing | A phrase that appears before or after its speech |
Review the whole video
- Play the captioned edit with sound and read each phrase as it appears.
- Pause at an error and note its approximate time and the correct wording.
- Ask for that specific correction, leaving the audio and other edits unchanged.
- Play the corrected section again, then continue through the rest of the video.
- Open the exported file and check the final captions, including the ending.
If the words are correct but arrive late, use the caption timing guide. For a new recording, clean audio guidance can help you make the speech easier to hear.
A specific correction
At 0:12 the caption should say "gesso". At 0:41 the name is "Vyra". Correct those words and leave the spoken audio, clip order and caption style unchanged. Let me review those sections.
Give the intended spelling of specialist terms before generating captions where possible. Still check the final text, since providing vocabulary does not guarantee every occurrence is correct.
FAQ
Can I post AI captions without proofreading? Review the whole video first. A generated caption track is a draft, and errors can appear anywhere in it.
Does clear audio guarantee correct captions? No. Clear speech makes the recording easier to review, but names and other words can still need correction. Check the complete text against the audio.
Can I correct the words without changing my voice? Yes. Specify the caption wording and ask to leave the spoken audio unchanged. Check the result in the preview and exported file.
Why are the words right but the captions still feel wrong? Check their timing, phrase length and position separately. Correct text can still appear too late or be difficult to read.
Should I check only names and numbers? Check every line. Pay extra attention to names and numbers because a small error can change their meaning.
