Numbers

Use phonetic guides in Numbers on iPad
If you have a Chinese, Japanese, or Korean keyboard set up for your Mac, iPhone, or iPad, you can apply phonetic guides to words written in any language even if you don’t use any of these keyboards.
If you don’t see the suggestions you’re looking for, make sure the spreadsheet is set up to use the language you want. Tap , tap Language & Region, tap Language, then select a language.
