Pre-built Subgrammar Library

If you've done any grammars of significant size or complexity you have by now noticed that building and testing grammars can be time consuming. In our continuing efforts to make your life easier, Voxeo has a number of the more common complex subgrammars available for download, which handle the subjects listed below.

Has anybody tried to use the credit card expiration grammar? The only way I can get it to work is by saying the full month name and the year, for example, "April 2006". It does not seem to want to take "oh four oh six" as is common practice.

Hello Dave,

I have tested both of your utterances to work successfully with my code snippet. You will find sample code below. Make sure you speak as clearly as possible, as I spoke the utterance as "oh four oh six" with flawless results.

Cheers,

Has anyone used the military_alphabet.grammar? If so, I would really appreciate any samples of how to use it as I am getting internal errors.

Thanks in advance!!!!!!!

Hello,

The GSL grammar library we have has only been tested on VoiceCenter 5.5, so it may be possible Prophecy does not like some of the syntax in the grammar. I might have a sample alphabet grammar you can use, but I will not have access to the directory until Monday. As such, I will post back tomorrow with my findings.

Hello,

Attached you will find an Alphanumeric grammar coded in grXML format. While it is not GSL, grXML is becoming the standard for VoiceXML, while GSL is on its way out. As such, I recommend you familiarize yourself with grXML/SRGS grammars. Also, this is not primed for words like alpha and bravo, but it would be easy to modify it as such.

Here's our tutorial section on grXML grammars:

Hope this helps,
