Append(String, Int32, Int32)

为语法元素的当前顺序追加重复的短语。
Append(GrammarBuilder, Int32, Int32)

为语法元素的当前顺序追加重复的语法元素。
Append(String)

为语法元素的当前顺序追加短语。
Append(String, SubsetMatchingMode)

Append(GrammarBuilder)

为语法元素的当前顺序追加语法元素。
Append(Choices)

为语法元素的当前顺序追加替代项集合。

注解

使用这些方法将语法元素追加到现有的 GrammarBuilder。 创建语法元素时，可以将它们追加到现有生成器，以逐步开发语音识别语法的约束。 每个元素都添加到当前元素序列的末尾。

此方法具有用于追加 GrammarBuilder、、String、 ChoicesSemanticResultKey和 SemanticResultValue 对象的重载。

重要

使用包含具有相同键名称的重复语义元素或多个语义元素（可重复修改同一语义元素的值）的语音识别语法时，语音识别器可能会引发异常。
