“ClaroSpeak can certainly be considered among the best available text-to-speech apps. There is not a lot of overt instruction, tutorials, or visual cues, but thats likely because the developer wanted to create a clean, sparse user interface to make it visually easy to work with. For tutorials, users have to go to the i tab and from there, exit to the developers website for the user guide. For users who want a lot of customizable options, including highlighting, frequent playback of content, and Dropbox compatibility, ClaroSpeak is an excellent option.”
