Narration quality control

Audio Proof Checker

Audio Proof Checker. Compare the finished narration with its script, inspect likely mismatches, and listen only where human judgment is needed.

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.

Transcription options

Your own key is kept only in this browser tab. Shared transcription uses the existing site quota.

    A review assistant

    Useful flags, never silent corrections.

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

    Speech recognition is not ground truth. Names, accents, music, and room noise can create false positives, so every issue can be played, selected in the script, or dismissed.

    FAQ

    Audio Proof Checker FAQs

    01

    How does the narration proof checker work?

    It transcribes your narration with the existing speech-to-text service, aligns the detected words with your approved 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 correction.
    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 whether the script, pronunciation, or audio needs correction.
    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 existing bring-your-own-key limits.
