Hi,
Could you provide the detail version of Office and Windows?
What's the language of Office did you use?
Go to File- options- Language and check if the preferred language is the same as system language.
Then I also suggest you disable all add-ins in Word and see if Read Aloud works.
Just checking in to see if the information was helpful. Please let us know if you would like further assistance.
