It looks like the following statements builds a grammar on the fly, which means that I don't need to specify the path to the grammar file.

pizza.orderObtainer = new SpeechObtainer(asr, 1, 5000);

pizza.orderObtainer.setGrammar("pizza_order", "", "result.interpretation.input", dft_min, dft_confirm, true);

pizza.orderObtainer.setTopSound("GP-DeliveryorTakeout");

pizza.orderObtainer.setBadSound("GP-NoDeliveryorTake-out");

pizza.orderObtainer.addItemAlias("Delivery", "Delivery");

pizza.orderObtainer.addItemAlias("Takeout,Pickup", "Pickup");

I tried the following, but I'm still getting the same error, detect_speech(unimrcp pizza_order file://usr/local/freeswitch/grammar/pizza_order.gram undefined).  What am I missing here? Thanks.

pizza.orderObtainer.setGrammar("pizza_order", "file://usr/local/freeswitch/grammar/pizza_order.gram", "result.interpretation.input", dft_min, dft_confirm, true);

pizza.orderObtainer.setGrammar("pizza_order", "/usr/local/freeswitch/grammar/pizza_order.gram", "result.interpretation.input", dft_min, dft_confirm, true);

Here's the content of pizza_order.gram:

#JSGF V1.0;

/**

  * JSGF Grammar for pizza_order

  */

grammar pizza_order;

public <delivery> = [ takeout | pickup | delivery ];

I found the definition of setGrammar(….)

        this.setGrammar = function (grammar_name, path, obj_path, min_score, confirm_score, halt) {

                this.asr.setGrammar(this.grammar_name);

When reviewing the log file, I also noticed the following message:  EXECUTE sofia/internal/1000@192.168.216.98 detect_speech(unimrcp pizza_order  undefined)

Now I'm wondering which folder ps_pizza.js looks for grammars. Thanks.

Here's the statement in ps_pizza.js.

pizza.orderObtainer.setGrammar("pizza_order", "", "result.interpretation.input", dft_min, dft_confirm, true);

"unimrcp" is the engine to use.  Make sure your mrcp profile is set up correctly.  The wiki has examples for various servers.

Hi,

I'm testing the pizza demo shipped with freeswitch. I tested it with pocketsphinx module, and that works.
Now I'm trying to do the same with a different ASR via unimrcp.

In ps_pizza.js, I replaced pocketsphinx in the following statement in ps_pizza.js with mod_unimrcp and unimrcp respectively, none of which works.
What am I missing here? Thanks.
var asr = new SpeechDetect(session, "pocketsphinx");
