● Verified AI audiobook correction

Fix a narration mistake by editing text — not re-recording.

Paste the corrected manuscript. mendwave finds the changed lines and regenerates just those passages in the narrator's own voice — imperceptibly. Every edit is machine-verified or flagged for review. No re-records. No voice cloning.

Why it sounds right

Three things make mendwave different from clicking a word and hoping.

✓

Verified, not vibes

Every edit is re-transcribed, speaker-matched, and loudness-checked. It passes machine QC or auto-retries — and anything that can't pass is flagged for a human, never shipped silently.

≣

Manuscript-diff batch

Paste the corrected text for the whole chapter. mendwave diffs it against the narration and fixes every changed line in one pass — not one click-a-word edit at a time.

🔒

No voice cloning

We verify each edit against the original narrator with a speaker model — but build, store, and sell no voiceprint. Narrator consent first; the master is never altered outside the splice.

🔒 Identity continuity, not cloning. Each regenerated passage is checked against the narrator's surrounding audio (ECAPA speaker similarity) so the voice matches — but no voice profile is trained or kept. Built on public-domain LibriVox audio for testing.
