Voice Selection
The voice selection is according to the language setting of the Word paragraph. The voices themselves come from the Mac OS.
Go to System | Accessibility | Speech to choose a language and voice pair, see below for more.
Word 2016 for Mac and earlier
For earlier versions of Office on Macintosh computers, the speaking is entirely done by the macOS not Office for Mac.
Some people prefer the Apple ‘speak selected text’ method and use its Speech option instead of Read Aloud in Word 365/2019.
To enable speech to text, go to System Preferences | Accessibility and look for the Speech
Speak selected text when the key is pressed – lets you choose a shortcut key.
Voice Selection
The speaking voice for Word comes from the MacOS Accessibility options, whether you use the Word 365/2019 Read Aloud or the Speech options in MacOS.
Go to System Preferences | Accessibility | Speech, select the voices pull-down list
Select an available voice or choose Customise for more. Scroll down to see the many options available.
As you’d expect, there are plenty of choices for US English among many.
We were tempted to try ‘Fiona’ a Scottish English voice.
Warning! Voices can take up a lot of disk space (a GB or more) which can be a concern on Mac laptops which are often chronically short of space.
Save some disk space by unchecking the ‘Upgrade to enhanced quality’ option available for some voices.
