我想这应该做的工作，即分配termchar值“”，用户可以输入＃作为输入。

<property name='termchar' value=' '></property> 

我得到流动错误：=

swi:SBjsi|501|SBjsi:ECMAScript engine exception|errmsg=SyntaxError: illegal character|line=1|linetxt=ivr_input == #|tokentxt=#\n 

Answer 1

的，如果内部标签的条件应该是

<if cond='ivr_input == '#''> 

，它工作正常。是啊！

Answer 2

在大多数平台上，“＃”键是终止字符。这可以通过在应用程序中设置属性“termchar”来改变。如果您想查看用户是否按下了“termchar”，则可以使用阴影变量“termchar”来查看他们按下的内容。有关此属性和阴影变量的更多详细信息，可以参考VoiceXML Specification。
