| Hi Eric,
The GSL grammar guide didn't move, but it did take a short vacation. However, I have called it, and asked it to get back on the job. Wisecracks aside, if you try the link again, it should come up for you, assuming you have a PDF reader. Steve Sax |

| Hi,
I am little lost here about planing grammar, so post this basic question. There is a target sentence, something like "Your room number is 5503", my program need to fetch two kind of things here, One is "room number", the other is "5503". HOw to prepare the grammar. Thanks. greg |

Hello Greg, This is a pretty broad question for me to address within the confines of a doc annotation, but I'll do my best. For any complex utterance values you wish to accept in your application, you will likely want to design a multi-rule subgrammar using either GSL or SRGS grammar formats. As this is a complex task, I very strongly advise that you start off with the following: - review our GSL subgrammar tutorial - review all documentation in this section dealing with GSL subgrammars - review all grXML/SRGS subgrammar documentation - download and review the 'grammar.zip' file from the below URL, and use if for reference: http://community.voxeo.com/library/grammar/library.jsp Best of luck! ~Matthew Henry |

| Hi Hemanth,
There are a lot of ways to write grammars,both GSL and GRXML grammars. If you are using inline GSL grammar it would be some thing like <grammar type="text/gsl">[WHAT EVER GRAMMAR YOU WANT TO BUILT]</grammar> If you are using external grammar it could be some thing like this <grammar src="digits.gsl#MAIN"/> where digit.gsl is an external gsl grammar and MAIN is the toplevel of the grammar. If you look through the documentation , there are lot of examples to help you with this. Thanks Sid |

| Hi,
I'm a beginner in voicexml and one of the questions i have is: I suppose that when using your browser, the speaker will speak the words in english. What do i have to do if I want the speaker to understand that he has to speak spanish? Or even more, what do i have to do if I want to talk in spanish and be understood by the application? I mean, is there any option in the Motorola browser that allows me to work using other languages? Maybe it's impossible and I must use another one, do you know any of them? Thanks and excuse my english, si'l vous plait. Marc |

Hi there, If you want to recognize a foreign language utterance, then you will have to set the ASR to use a recognition engine to the appropriate locale. At present, our US customers only have the option for English, and Spanish, (so you are in luck!). You can use the following code sample below, which is annotated for your convenience to start developing a Spanish application. Note that this is available only for the Voicecenter 5.5 release, and is *not* supported in the Prophecy/Voicecenter 7.0 platform: <?xml version="1.0" encoding="UTF-8"?> <!-- ****************************************** --> <!-- xml:lang attribute invokes the Spanish ASR --> <!-- ****************************************** --> <vxml version="2.0" xmlns="http://www.w3.org/2001/vxml" xmlns:voxeo="http://community.voxeo.com/xmlns/vxml" xml:lang="es-MX"> <!-- ******************************* --> <!-- sets the rhetorical spanish TTS --> <!-- ******************************* --> <property name="nuance.core.tts.ResourceName" value="es-MX.F023" /> <form id="F1"> <field name="F_1" type="digits?length=3"> <prompt bargein="true"> hola senor. </prompt> <filled> <value expr="F_1"/> <log expr="'**********INTERP*************' + F_1$.interpretation.F_1" /> <log expr="'**********UTTERANCE*************' + F_1$.utterance" /> <log expr="'**********CONFIDENCE*************' + F_1$.confidence" /> <log expr="'**********INPUTMODE*************' + F_1$.inputmode" /> </filled> </field> </form> </vxml> Regards, ~Matthew henry |

| Hi, I have a very simple inline grammar:
<grammar type="text/gsl"> [ (one) (two) (three) (four) (five) (six) (seven) (eight) (nine) (ten) ] </grammar> The goal is to have the user say a number between one and ten. However numbers like eleven, fourteen, etc. are matched as well. How come? |

| Hello 42Entertainment,
Do you have a field with a type="digits" in your application? A field type="digits" will invoke the builtin digits grammar. This builtin grammar will allow for a wide range of numbers, including anything up to 16 digits long. If this is not the case, I would like to see the xml for the document exhibiting this behavior. If you do not want to post the code here in a public forum, please feel free to open a private account ticket, and reference this thread in that ticket. If there is something I am missing here, or if there is anything else I can do, please let me know. All the best, Dante Vitulano Voxeo Corporation |
