Hello AAzevedo71,
Thank you for the question. I recommend enabling 'Speak selected text when the key is pressed' in your System Preferences so that your Mac will read back the text in Preview.
Follow these steps:
If you have trouble reading text on your screen, you can have your Mac speak text that’s on the screen when you press a key or set of keys.
Listen to the app reading aloud or read on screen web pages, news articles, long emails, TXT, PDF, DOC, DOCX, RTF, OpenOffice documens, EPUB, MOBI, PRC, AZW and FB2 ebooks and more. It's an HTML reader, document reader and ebook reader all in one, both for reading on-screen, or listening when your eyes hurt, malfunction or are busy elsewhere. FEATURES:. Open text, PDF, DOC, DOCX, RTF. Read Aloud with VoiceOver. The Kindle app supports the iOS VoiceOver accessibility feature. With VoiceOver enabled on your device, audio support is provided for many books and features. From your iOS device Home, select the Settings icon. Select General. Under General, select Accessibility. Under Vision, select VoiceOver. Tap On or Off.
- Choose Apple menu > System Preferences, click Dictation & Speech, then click Text to Speech.
- Select the “Speak selected text when the key is pressed” checkbox.
By default, speaking is enabled when you press Option-Esc. To choose a different key, click Change Key, press one or more modifier keys (Command, Shift, Option, or Control) together with another key, then click OK. - To have your Mac start speaking, press the specified key. To stop the speaking, press the key again.
If text is selected when you press the key, the selected text is spoken. Otherwise, available text items in the current window are spoken; for example, if Mail is the current window, an email message is read. If no text items are available, you hear a beep.

Thank you for using Apple Support Communities.

Mac helps you find your focus so you can think big. Because it’s built with neurodiversity in mind. Text to Speech adds auditory reinforcement to what you’re reading. Word Completion helps boost word-building skills. And Dark Mode makes it easier to focus on the task at hand.
Text to SpeechGo from written word to spoken word.
If you learn better when you can hear what you’re reading or writing, Text to Speech can help by adding an auditory component to books, websites, or homework assignments. Highlight any text and hear it read aloud in more than 70 voices across 42 languages. You can even adjust the speaking rate.
Hover TextGet a quick size boost of what you’re reading.
Hover Text makes it easier to view text on your display. Just hover over any text with your cursor and press Command. You’ll get a dedicated window with a large, high-resolution version of your selection. You can even choose the fonts and colors that work best for you.
Dark ModeLet your content take center screen.
Dark Mode transforms the desktop and built-in apps with a dark color scheme that helps you focus on your work.1 The fine points of your content take center screen as toolbars and menus recede into the background. Light text against darker backdrops in Mail, Safari Reader, Calendar, and more makes everything easier to read in low lighting conditions.
SiriAll you have to do is ask. Or type.
If you prefer to communicate by typing, you can set Siri to “Type to Siri” mode to request web searches, send messages, track down documents, set reminders, or even turn on your go-to accessibility settings.2
Word CompletionLet Mac finish what you started.
To help with vocabulary and word-building skills, macOS provides word completion in apps like TextEdit and Pages. After typing just a few letters, press the F5 key and macOS suggests words. Select the word you want, and macOS completes it for you.
DictionaryFind even more meaning in your Mac.
If you have a question about a word or phrase, just look it up in the built-in Dictionary app — from anywhere in macOS. Get quick access to definitions and synonyms that help with grammar, spelling, and pronunciation.
SpeechCommunicate the way that’s right for you.
FaceTime lets you communicate visually, whether through the use of sign language, gestures, or facial expressions.3 iMessage lets you chat with others via text. And Text to Speech lets you hear words read aloud to help with expressive speech development — or even communicates for you by speaking the words you type.
