[WPSL]Speech Recognizer Grammars

Question

Firstly, am I correct in thinking that there is no GrammarBuilder in the WP8 sdk ?

I've looked at SRGS XML but find it rather baffling.  I don't suppose there is some kind of graphical grammar builder that can create the definitions for me ?

Anyway here's what I need to recognise... A 'sentence' featuring a Number, an Instruction and a Color. 

Such as "12.5 Top Red" or "230 Left Blue"

I can recognise each element individually by using AddGrammarFromList but have to pause between each word.

Any ideas ?

Hi theresonlyonefinmaf,

Firstly, for the GrammarBuilder class, from this article https://msdn.microsoft.com/en-us/library/system.speech.recognition.grammarbuilder(v=vs.110).aspx,

there is no version support for windows phone 8.

Then can I confirm that you are developing a windows phone 8 application,not windows phone 8.1 , right? And you don't want to use SRGS grammars  https://msdn.microsoft.com/en-us/library/windows/apps/jj207051(v=vs.105).aspx to meet your requirements since you think it is boring, right? 

And are you using the List grammars?

Not boring but baffling (not easy to understand)

Is the GrammarBuilder in 8.1 ?

Hi theresonlyonefinmaf,

>>Is the GrammarBuilder in 8.1 ?

We cannot use the GrammarBuilder in the Windows Phone8.1, because it is not supported. 

>>Not boring but baffling (not easy to understand) 

But currently it seems that we need to use the SRGS XML to implement your requirement. Because the SRGS grammars provide a full set of features to help you architect complex voice interaction with our apps. For example, with SRGS grammars we can specify the  order in which words and phrases must be spoken to be recognized and we can also combine words from multiple lists and phrases to be recognized. For the detailed information, I will recommend you refer to the following articles to help you better understand about the SRGS grammars:
