RE: differentiate between InterdigitTimeOut and invalidcharacter

Hi Karthik,
You can accept variable length of digits in your grammar and let the post processing decide if the input was valid - in this case you wont get nomatch for IDT. The nomatch event would be thrown only in case if an invalid digit is entered.

Dear Deepa,

               Thanks for your reply. We have to differentiate because if invalid char is pressed, I have to reprompt, or IDT then I may terminate the session. Is there any other way to do this?

 

As part of your post processing (validating it against the active grammars at that time, you can find out if the nomatch is because of an invalid character (in this case the length of input collected will match the expected length ONLY in case of fixed length grammars.) 

               >>> I cant understand this. Can you elaborate more on this or provide me some pointers.

            

 

Thanks

Only nomatch event gets generated. But then does it really make a difference? 


How do you know that input collection is done and that you need not wait for anymore input? 


Only because of IDT.


 Another way would be if you knew that you are expecting a fixed length of input (say). This will depend upon the active grammar. If the grammar is such that you can determine that a fixed length input is required then you can say that input collection is over after the user enters the input of expected length.


Suppose you have multiple grammars active, which are not of the fixed length kind, then you don't know if input digit collection is over till IDT. 


As part of your post processing (validating it against the active grammars at that time, you can find out if the nomatch is because of an invalid character (in this case the length of input collected will match the expected length ONLY in case of fixed length grammars.)

Hello all,

            In VXML, how can I differentiate whether nomatch event is for IDTO or for Invalid character is entered

 

Thanks in Advance
