ClaroPDF is an accessible, reading and study PDF tool. You can use it to annotate, mark up and save PDF files which are then still fully compatible with Adobe Reader and other PDF apps. You can then have accessible text PDF files read back to you with a human quality voice & synchronised highlighting.
Alongside the full range of iOS system voices, ClaroPDF Pro contains human quality text to speech English voices and a range of synchronised colour highlighting options. A ‘Speak in Background’ option lets you listen to a PDF while viewing another app. The ‘Speak on tap’ (either from the tapped sentence or the page’s first sentence) and ‘Stop on tap’ options make speech easy to control. Over 40 additional high quality voices are available in 27 different languages through In-App purchase, so you can easily customise ClaroPDF’s voice. The voices are all built into the app, so an Internet connection is not needed to speak text.
ClaroPDF allows the background colour of the PDF to be changed, to enhance readability. ClaroPDF fully supports VoiceOver. Image PDF files cannot be spoken by ClaroPDF voices, but can be fully viewed and annotated with ClaroPDF.
