NaturalReader はあらゆるものを変換します 文章, PDF, image, webpage, and physical book into natural-sounding audio.
Most people never move past the free online reader.
This guide shows you how to use NaturalReader properly, feature by feature.

NaturalReaderのプロ向けヒントとショートカット
After eight months of daily reading, these are the habits that stuck.
キーボードショートカット
| アクション | ショートカット |
|---|---|
| Play or pause | 空間 |
| Skip forward one sentence | Right arrow |
| Skip back one sentence | Left arrow |
| Read selected text aloud | Ctrl + Shift + R |
ほとんどの人が見逃す隠れた機能
- Highlight-to-read on any webpage: Select text in the browser, then let the Chrome extension read it back 即座に.
- Google Docs support: The extension reads Google Docs and Gmail without copying anything across.
- Speed memory: Reading speed saves per document, so a dense article can run slower than a blog post.
NaturalReaderでよくある間違いを避ける方法
Mistake #1: Selling Audio Made on a Personal Plan
❌ 間違い: Publishing audio files created on personal use versions to clients or paid channels.
✅ 右: Personal use versions cover personal use only. For commercial purposes, buy a commercial license through NaturalReader Commercial before any commercial use.
Mistake #2: Ignoring the Monthly Character Cap
❌ 間違い: Batch converting text all month, then hitting a wall mid-project.
✅ 右: NaturalReader Online allows 1 million characters per month for MP3 conversions. Track heavy exports.
Mistake #3: Skipping the Pronunciation Editor
❌ 間違い: Re-recording whole sections because one brand name reads wrong.
✅ 右: Add the fix once in the pronunciation editor. It applies to every future read.
NaturalReaderのトラブルシューティング
Problem: The Chrome Extension Will Not Read a Page
原因: The extension needs a page reload after install from the Chrome Web Store.
修理: Refresh the tab, then confirm the extension has permission for web pages and Google Docs.
Problem: A Scanned PDF Plays Nothing
原因: Scanned documents are images, so there is no text layer to read.
修理: Run optical character recognition on the file first, then reopen it.
Problem: You Were Charged After Cancelling
原因: Plans auto renew, and cancelling never triggers a refund on its own.
修理: Cancel before the billing period closes. Access continues through the current billing period. Then request the refund separately using the blue chat icon in the bottom right corner.
📌 注記: Yearly plans allow refund requests for 30 days. Monthly plans allow 14 days.
