Not being a iOS person (don’t own or know how to operate Apple products) I have to take this report at face value.
Dicater is an add-on app to extend the functionality of the Text to Speech function in Mac’s.BY adding the interface, the user can now pause, play, fast-forward and rewind. The most significant control, especially for those with learning disabilities, is the “Teleprompter” control.
This control adds tracking or highlighting of the words as spoken, adding a visual cue to the audio. There is a setting to font color and size. The default voice can also be changed to any other voice already installed on the system.
