Language codes for non-English recognition | Are they different on Android and iOS?

[The-Linguist]

On this page I see that "zh-CN" for mainland and "zh-TW" for Taiwan are listed for Chinese; and "zh" is not listed. But on developers.apple.com like this page I often encounter "zh-Hans" and "zh-Hant". Note that this confusion applies to most non-English languages, i.e. not only Chinese. EDIT-1: Tested on Mac OS, and setLanguage("zh"); works and setLanguage("zh-Hans"); doesn't work. EDIT-2: Tried listening to Arabic on Mac OS. For some reason setLanguage("ar"); makes it return possible phrases as recognized speech but no annyang commands fired (Safari 16.0) even though the string values were obviously matching. So I had to quit using annyang.addCommands(commands); and instead I did something like,

annyang.addCallback('result', function() {
      // Run a for loop and use .search() to see if there is a match
});

and it worked.

Additional things to mention:

• Chrome seems to work fine with just "en" inside setLanguage() instead any of en-GB en-US en-AU en-CA en-IN en-NZ en-ZA and is good at catching both British and American pronunciations.
• It looks like there is now also the "Edge" case about which I've never been able to run any tests. But would like to know if it expects exactly what Chrome expects or is any different.

Upon further and deeper search I've found https://www.ibabbleon.com/iOS-Language-Codes-ISO-639.html

It would be great if everyone «who gets to test it» shared his/her test results to let us find how reliable that is.

EDIT: As mentioned above in javascript annyang.setLanguage("zh"); works and annyang.setLanguage("zh-Hans"); doesn't work.
