Free · Unlimited length · Real neural voice · 100% private

Unlimited text to speech.
Actually natural. Still private.

Paste text, upload a document, or read a PDF aloud — HearYourDocs converts it with a real neural voice, entirely inside your browser, and hands you back one real audio file when you're done. No character wall, no account, and nothing is ever uploaded to a server.

You appear to be on a slow or data-saver connection. HD Voice is a one-time ~50MB download — grab it now, or start instantly with the basic voice and switch to HD later from the voice menu.

Preparing your voice — one-time download, usually 20–40s on Wi-Fi.
Using the lighter voice model for your connection/device.
About the voice: HD Voice is a real neural voice model (Kokoro) that runs entirely on your device — nothing is uploaded, and it stays free and unlimited because there's no server bill to recoup. The only trade-off is a one-time download (roughly 50–90MB depending on your device), cached after that so it's instant on repeat visits — and works offline once it's cached.

Text to speech, compared

Unlimited length. A real neural voice. Fully private. Pick any two, everywhere else.

Free tools cap you or sound robotic. Neural tools cost money or upload your text to a server. We tested the popular ones — nobody combines all three. HearYourDocs runs the whole voice model on your device, so there's no server bill to recoup and nothing to lock behind a paywall.

Verify it yourself

Open your browser's Network tab while converting. You'll see zero requests carrying your text or file — because none are made. We're not asking you to trust a privacy policy, we're showing you the traffic.

Analytics, not content

We use standard page analytics (page views, button clicks) to see what's useful. Your document text and audio never touch analytics, storage, or any server — they only exist in your browser tab.

Open technology

The neural voice model behind HD Voice, Kokoro, is an open-source model — not a proprietary black box you have to take our word for.

Text to speech FAQ

Common questions, answered straight.

Yes, with no hidden catch — it runs on your device instead of a paid cloud voice API, so there's no per-character cost to us and nothing to ration. That's different from tools that advertise "free" but cap you once their server costs start adding up.
Correct. Your document is processed sentence by sentence and merged into one file at the end, so there's no hard cap from us. A longer document just takes longer to process, since your browser is doing the work in real time.
You can paste text, or upload a .txt, .pdf, or .docx file directly — the text is extracted automatically in your browser, no copy-pasting required. See our PDF to audio guide for details.
Yes — press play, let it finish, then press download. You get a real .mp3 by default (smaller, easier on phone storage), and you can pick .wav from the same button if you want the uncompressed version. Both are generated live in your browser. No waitlist, no email required.
No. The voice engine and the PDF/DOCX text extraction both run directly in your browser tab. Your file and text never leave your device — nothing to intercept, nothing stored on a server.
HD Voice is a real neural voice model, not a cloud API — so instead of your text being sent to a server, the model itself is sent to your browser once, then cached. That's the honest trade-off behind a natural-sounding voice that's still free, unlimited, and private: a one-time download, not an ongoing quality cap.
Yes, after the first successful load. Install it from the "Install app" button (or your browser's install/add-to-home-screen prompt) and the voice model stays cached for offline use — no connection needed on your next visit.
