Language not supported on iOS device

[AENeuro]

I used the below code to try to speak Chinese, and it worked perfectly well on windows, android and MacOS, but for iOS devices, it just speaks English what so ever.
I tried to use getvoices() and it turns out that there ARE chinses voices supported.
So wierd

<SayButton speak="123" voice={voices => [].find.call(voices, v => v.lang === "zh-CN")} > Speak! </SayButton>
