Read&Write and Immersive Reader are the only options that can be used with desktop applications (e.g., Microsoft Word, Acrobat Reader, etc.). Snap&Read and Natural Reader are browser-based options. Depending on your reading needs, it may make sense to have “several tools in the toolbox”.
Below, you will find a comparison chart to assist you with identifying how the core features of each application differs:

E-reader apps are basic TTS applications that are limited in functionality. In most instances, they only allow the ability to play/pause speech and change the speech synthesizer. Although they are not as feature-rich as applications like Read&Write or Natural Reader, they can still be useful for those who need basic text-to-speech support.

- Speak Selected Text (Mac) opens a new window

Audiobook supports differ from text-speech tools in that the former is typically narrated with human voices. In many instances, it may be the author, a volunteer, or even a paid actor. See Audiobooks for more information.
