In my experience, folks record the prompts as English-US but labeled as, say, Greeting_Hmong. Then designate which prompt to play at runtime. System prompts that are embedded and cannot be specified (like the ones in the Collect Input responses or Estimated Wait Time, etc.) just have to be in English, and hope that folks can understand well enough to get by.
Hopefully someone out there has come up with a better workaround.
