A family of Microsoft word processing software products for creating web, email, and print documents.
I kept digging and found an answer~ It's odd and around the field, so I'll post it here (slightly edited for readability).
Note: the forum stripped out the images, so you'll want to go to the link in order to see the screenshots, if you want them.
It's from https://www.eduhk.hk/ocio/content/faq-how-add-phonetic-guides-注音標示-text-ms-word
(Now, if only there was a way to change the default input size and formatting...)
Procedures: (For Word 2007/2010/2013)
- Firstly, highlight the text you need effected.
- Then you need to change the language for your phonetic guide. Click on the language from the status bar.
- Choose the language you need. (e.g. Chinese (PRC)). Then press "OK. [Edit: I found that unclicking the box for Detect Langauge Automatically, was helpful.]
- Now, from the "Home" tab, click on the "Phonetic Guide" button.
- Change the settings you need, then press OK
