[Bug]: Pronunciation assessment for Korean is always scoring high all of a sudden even in your own Azure AI Speech Studio

[riiight]

What happened?

Pronunciation assessment for Korean was working fine. Sometime in the past few days/weeks, it stopped working properly. Now, even if you completely mispronounce a word in Korean, it will score very high (90%+).

You can see this even on your own Azure AI Speech Studio (https://speech.microsoft.com/portal/811cc118d47c430faea884b0299c43f1/pronunciationassessmenttool). Steps to reproduce there:

1. Choose Korean for the Pronunciation Assessment language.
2. Instead of using Sample 1, switch to "Your Own" and enter this for the test phrase: "북한".
3. Say "ha ha" or anything else. You will get a 90+ score.

Version
