Hi WR. I'm Greg, 10 years awarded Windows MVP, here to help you.
I've seen this reported several times recently. Apparently Microsoft Zira is not working for reading aloud in Windows 10 due to an Update.
SInce it's been a year since it was reported below, are you fully updated with WIndows and Office? Check in Windows in Settings > System > About if you have Version 22H2 and if not install the Media Creation Tool from this link https://www.microsoft.com/en-in/software-downlo... choose Download Tool Now, install the tool, open it and choose Upgrade this PC Now. This will save your files and apps while bringing you up to the latest version by the most stable method. It will also bring all of your Updates current and solve most problems since it reinstalls Windows.
To update to latest version of Office see here:

There are also possible fixes reported here:

If nothing there works then to report this bug to Microsoft you may be able to help improve this product/experience by using the Feedback Hub in Start Menu, especially if you are willing to share logs and other requested information. While they will probably not see this here in the forums, Microsoft developers DO read feedback from customers that comes in via the Feedback Hub, so that is a great way to share your thoughts on how to better serve you as a customer.
Report back results for each step so I know what else to suggest.
Feel free to ask back any questions. Based on the results you post back I may have other suggestions if necessary.
