语音识别（有时说话，有时不说话）

Question

只有我遇到了这个奇怪的问题吗？有时它会说话，有时它不会。在我开始调试它大约 3-5 秒后，它会自动执行语音 == "Hello Enzo" 而没有说任何话。 （没有背景声音，所以我确定只有我在说话）

有时当我说它不起作用时，我不得不一次又一次地开始调试它，直到它听到并回答我。

下面是一些debug

快速搜索跟踪顶部的错误：“SAPI 未实现拼音字母选择”显示一些人有类似问题。

尝试为您的 GrammarBuilder 设置文化，而不是这样：

_recognizer.LoadGrammar(new Grammar(new GrammarBuilder(new Choices(System.IO.File.ReadAllLines(@"C:\Commands.txt")))));

试试这个：

GrammarBuilder gb = new GrammarBuilder(new Choices(System.IO.File.ReadAllLines(@"C:\Commands.txt")));
            gb.Culture = new CultureInfo("en-US");
            _recognizer.LoadGrammar(new Grammar(gb));
