Pratyush - A <GeeK>!!!

Know the secret of writing well? Read out aloud.

Mac has a feature to read out any selected text. We can enable it by:
Going to system preferences >> Accessibility >> Speech >> Speak selected text with shortcut

Enable speech on Mac

I use the default shortcut: Option + Esc.
Same panel also provides the option to select voice and read speed.

Now select any text and press the shortcut to read it out.
