I prefer to use VoiceDream reader on iOS since I don't get any benefit of syncing with Natural Reader on iOS, VoiceReader does a better job of presenting media when I need to see the content in original format, but if Natural Reader came out with syncing I would switch to using Natural Reader for most of my reading which does not require reading in original format in a heartbeat.This article applies to Microsoft Edge version 77 or later. Settings is a little tricky since availability of voices is not the same on all devices.

I feel strongly that documents should be synced two-way between all the clients be it desktop, smart phone and webapp, not just in file replication but in playback position. The biggest improvement that I have asked for several times and still have yet to see implemented is syncing between Natural reader Desktop and the smartphone equivalent. Also you can utilize voices you have installed from other sources asides from the voices that Natural Reader offers. Some people may ask why not just use Mac OS's native Services and Voiceover? With Natural Reader 16 you have on-the-fly control over voice selection, speech speed, plus you still retrain playback controls, and it shows the text like 'captions' in a tiny but very functional window. it is basically the webapp but wrapped in an app container, the one exception is that the desktop app includes what was formerly known as the Floating Bar, which is now called the Miniboard and resides under the overflow menu 'More', a feature I use a lot to readback whatever text I've selected with my cursor in whatever app avoiding the need to cut and paste or download and upload. With Natural Reader 16, the desktop app is finally on par with the webapp. Adamlogan's Experience This is my preferred software solution on Mac OS for text to speech.
