FAQ
1. Can UPDF read aloud a PDF while simultaneously generating a summary?
UPDF itself does not support the ability to read aloud and generate summaries simultaneously. Typically, text-to-speech and summary generation are separate features. You can first use UPDF’s read aloud function to read the document aloud, then use UPDF AI’s summarization tool to create a summary. However, these two functions cannot be performed at the same time.
Does UPDF’s “Speak” work on protected PDFs?
Yes, but there are limitations due to the PDF’s security settings. If you have permission, ask the creator to remove the protection. Additionally, if you have the password, you can also open the file with UPDF. UPDF supports unlocking PDF. Alternatively, use other tools to convert or decrypt the file, but ensure compliance with legal and ethical guidelines.
Why can’t my iPhone read aloud PDFs?
If your iPhone is unable to read aloud PDF files, it may be due to the following reasons:
Protected PDF: Encrypted or restricted PDFs may block the feature.
Language Settings: Check your device’s language and voice settings.
UPDF Settings: Ensure the app is configured and the text-to-speech feature is turned on.
Permissions: Grant UPDF access to your documents.
File Format: Only standard PDFs are supported for reading aloud.
