Comparing 4 PDF Text-To-Speech iOS Apps: Voice Dream Reader, Capti Voice, NaturalReader, and vBookz PDF

Lately, I’ve been really into listening to as much content as possible. In addition to podcasts, web pages, and audiobooks, I started listening to PDF documents these days.

iOS native text-to-speech (TTS) feature is fine for short text but isn’t great for PDFs. So I started searching for an app that suits my need.

Trying Out Four Apps

At first, Capti Voice app seemed to be very promising. But after I used it for a few days, I found the rich text mode (free version) to be buggy with PDF documents. I tried the original layout mode with a free upgrade trial and it worked okay.

Then I tried NaturalReader. I didn’t have much to complain about this one, but I wasn’t convinced enough to upgrade to the paid version.

The next one was vBookz PDF Voice Reader. Similar to NaturalReader, this is also a solid app with basic features for reading PDF files. If you like following the text while it’s being read, this app has a nice text mode that makes it easy.

Then finally, I read several good reviews about Voice Dream Reader and decided to purchase it.

Winner: Voice Dream Reader

I immediately liked Voice Dream Reader. Things I liked:

  • The navigation control is much easier than in other apps
  • Lots of shortcut gestures
  • You can add custom pronunciation of words/phrases via the dictionary feature
  • In addition to iOS system voices, you can add one of the voices provided by Acapela/Ivona/ NeoSpeech comes with the app for free
  • The app is stable; no annoying issues like skipping to random locations

I wish it had a free trial version, but other than that I have no complaints.

For Free: Capti Voice

Even though I wasn’t happy at all with the unsteadiness of the app’s rich text mode, I think it’s an okay solution for someone who is looking for a free PDF reading app.
