如何在Microsoft access中实现变音

Question

我想在Microsoft Access中使用变音算法进行模式匹配。我在http://www.snakelegs.org/2008/01/18/double-metaphone-visual-basic-implementation/上找到了一个代码但是它不工作，相反，Microsoft Access 2007挂起了。

我试过soundex，但它达不到我的目的。

Answer 1

@Daredev，我不能直接回答你的问题，但可以直接到关于模糊搜索的资源与VBA/Access中的例子。不幸的是，它们都是德语:

• Michael Zimmermann: http://donkarl.com/Downloads/AEK/AEK13_Dubletten.zip

Answer 2

我发现以下内容非常有用。首先，Metaphone有3个版本-

1. 变音位
双变音位
3. 变音位V3

我在下面提供了Metaphone的代码。我在这里找到的，我编辑了一下代码。没有功能改变。

我还在这里找到了一些增强版的soundex。

如果您正在寻找双变音位，请访问这里。它在Visual Basic中提供COM包装器以语音搜索名称列表，以及数据库表中的名称。

注意:请评论，上述算法中哪一个适合您的场景。

这也是必要的
