Script vs sound

Proof the words, not the waveform.

Upload narration and compare its transcript with the approved script. The checker points to likely omissions, additions, and substitutions so you can review the risky moments first.

    Useful flags, never silent fixes.

    The checker uses word alignment to narrow a long recording down to moments worth hearing. Missing, added, and replaced words appear separately.

    Speech recognition isn’t perfect. Names, accents, music, and room noise can cause false positives. So you can play, select, or dismiss every issue.

    FAQ

    Frequently asked questions

    01

    How does the narration proof checker work?

    It transcribes your narration using the existing speech-to-text service, aligns the words with your script, and lists likely missing, unexpected, or substituted words.
    02

    Can a transcription difference be a false alarm?

    Yes. Speech recognition can mishear correct narration, especially names and technical terms. Every result is a review cue, not an automatic fix.
    03

    Does the checker rewrite or regenerate my narration?

    No. It helps you select the relevant script text and play the approximate audio range. You decide if the script, pronunciation, or audio needs fixing.
    04

    What are the limits?

    Standalone scripts are limited to 5,000 characters. Shared transcription uses the existing site allowance; a user-provided Groq key uses the larger bring-your-own-key limits.
