Why "Siri" do not support more international languages including Thai?

I have seen the voice2text-convertion-app of "Dragon Dictation". It supports the more international languages including Thai.

I speak Thai naturally to this app, it would process almostly correct words on typing note.

However, It cannot process the type of human name in Thai. With more improvement in this session for Siri, it would be acceptable for release.

For a few year, I haven't seen Siri supporting more and more languages including Thai. We may have the new app of voice language translator.

Therefore, :Siri" would be more valuable for multinational language. I may deside to buy a new one again.

Thank U. for readling my complaint.
