Need help with your PDF reading and listening journey? We are here to assist you with any questions, feedback, or technical issues you may encounter while using the DocuVoice app.

Frequently Asked Questions (FAQ)

1. How does the AI generate the voice for my PDF? DocuVoice converts your PDFs into spoken audio using on-device text-parsing and voice-synthesis technology. When you import a PDF, the App processes the document layout locally to determine the correct reading order, resolves line-wrapping, and splits the text into sentences. The voice synthesis is then processed entirely offline on your device using built-in artificial intelligence, producing realistic, human-like voice outputs.

2. Are my documents and personal text data safe? Absolutely. Your privacy is our highest priority. DocuVoice operates on a strict offline-first, privacy-first architecture:

• No Cloud Transmission: Your PDF files, extracted text, and synthesized audio streams are never sent to external servers or cloud AI providers. All parsing and speech synthesis happen locally on your device.
• Local Storage: Your documents, titles, and reading progress (last read page and sentence indices) are stored exclusively in a local database container on your iPhone.

3. What if I change my phone or delete the app? Because DocuVoice stores all your imported documents and reading progress locally on your device to protect your privacy, we do not have cloud backups of your files on our servers. If you delete the app or change your device, your documents and reading progress will be permanently lost unless you restore your device from an Apple iCloud backup.

4. Why does a sentence highlight or pronunciation drift on some pages? While our layout-aware parser is highly advanced, PDFs are complex documents. Multi-column tables, mathematical formulas, embedded code snippets, or low-quality scanned images without proper text layers can occasionally affect text extraction alignment. If a sentence's highlight alignment drifts, you can tap directly on the next readable sentence to resynchronize the reader.

5. How do I adjust the reading speed or change the voice? You can customize your listening experience directly in the reader's playback controller:

• Change Speed: Tap the speed badge (e.g., "1.0x") at the bottom right to choose from 0.8x, 1.0x, 1.2x, 1.5x, or 2.0x speeds.
• Change Voice: Tap the gear icon at the bottom left to switch between Male and Female voices, or to manually select the reading language.

6. Do I need to pay for a premium subscription? DocuVoice is currently fully unlocked. All premium features—including local high-quality AI voices, custom speeds, and unlimited document imports—are available completely free of charge. No subscription or payment is required.
