Für deutsche Text zwar nicht so gut geeignet, aber trotzdem ein netter Tipp von MacWorld:
Having your Mac read text documents to you is a great way to proofread your writing — you’re more likely to notice mistakes when you hear them. If you’re using Microsoft Word, the service is unavailable. Although you could copy and paste your Word document into TextEdit, there’s a simple way to hear your text within its original application. Open the Speech preference pane, click on the Spoken User Interface tab, and enable the Selected Text When The Key Is Pressed option. Click on Change Key, and enter a keyboard command for activating text-to-speech. Once you’ve set this up, you can select the text in any application and press your keyboard command to hear the text read aloud. Press the keyboard command again to stop it.
