Why doesn't libra office support use of Windows 10 Cortana Voice to text?

When I try to dictate text into libra office documentation via Cortana, it will not function. Why is this? Does anybody know about this that could help correct a problem that I might be having? I have recently installed W10 into a new computer and have called M$ about this problem but all they are concerned with is charging my credit card for phone support. Can someone help me with this?

There is no such thing called libra office

Please file a bug report. Unfortunately, Windows’ voice recognition language must match OS UI language, which disables e.g. me to test or work on this, me having a Russian localized Windows without voice recognition support from MS.
