我张贴了这整个代码，以便读者可以知道行号，以便提供帮助。当我运行这段c++/CLI代码时，我得到了很多我无法解决的错误:

所有这些错误都引用了下面的代码片段，它是从上面的
中提取出来的private: System::Void button3_Click(System::Object^ sender, System::EventArgs^ e)
{
SpeechRecognizer sr;
array<String>^ words = gcnew array<String>(3);
words[0] = "red";
words[1] = "green";
words[2] = "red";
Choices colors;
colors.Add(words);
GrammarBuilder gb;
gb.Append(colors);
Grammar g(gb);
sr.LoadGrammar(g);
System::IntPtr ptr = gcnew System::IntPtr(&sr_SpeechRecognized);
sr.SpeechRecognized += gcnew System::EventHandler(this,ptr);
}
void sr_SpeechRecognized(System::Object ^sender, SpeechRecognizedEventArgs^ e)
{
}
为什么我得到这些错误?
我认为它应该是一个SpeechRecognizer^在你的功能开始。别忘了加gcnew
不知道Choices这样的类型是很难的。但是，words数组应该这样使用:
array<String^>^ words = gcnew array<String^>(3);
words[0] = "red";
words[1] = "green";
words[2] = "red";
此外,GrammarBuilder。Append似乎期望String^，但您使用Choices调用它。类似地，您需要修复Grammar构造函数的使用(需要String^而不是GrammarBuilder)。
首先，您需要添加引用到您的项目System::Speech，然后使用下一个名称空间:
using namespace System::Speech::Synthesis;
using namespace System::Speech::Recognition;
using namespace System::Speech::AudioFormat;
//you put a C# code instead of C++/Cli, try this:
private: System::Void button1_Click(System::Object^ sender, System::EventArgs^ e) {
SpeechSynthesizer^ synth=gcnew SpeechSynthesizer();
synth->Rate = -2;
synth->Volume = 100;
synth->Speak("She say: This is real C++/Cli");
}
这是第一个按钮的解决方案，现在尝试自己解决下一个语法。好运！:)
