用sapi语音阅读外国字母

Question

我从网上获得了一个代码，该代码读取了一个给定的声明：

Option Explicit
Dim Zira, David

Set Zira = CreateObject("SAPI.spvoice")
Set Zira.Voice = Zira.GetVoices.Item(1)

Set David = CreateObject("SAPI.spvoice")
Set David.Voice = David.GetVoices.Item(0)
David.Rate = 0
David.Speak "the statement that is going to be readed"

Zira.Rate = 0
Zira.Speak "the statement that is going to be readed"

但我想要的是让它说一首没有英语声音的外国字母，例如阿姆哈拉语በ。如果我把它直接放在代码中会产生意想不到的结果。如果有人有想法分享，我会很高兴。如果有其他语言的程序可以做到这一点，我不介意。
