VoiceXML 2.1 Development Guide

<field> element

The field element facilitates a dialog which allows the interpreter to collect information from the user. Caller utterances are matched against any active grammars, until the element’s filled condition is executed.

usage

<field cond="CDATA" expr="CDATA" modal="(true|false)" name="NMTOKEN" slot="NMTOKEN" type="CDATA">

attributes

cond	Data Type: CDATA	Default: Optional (true)
	The cond attribute specifies a Boolean expression, which must equate to ‘true’ in order for the content to be visited and executed. (Additionally, the expr attribute must also be set to ‘undefined’, see below).
expr	Data Type: CDATA	Default: Optional
	The expr attribute specifies the initial value of the element; if this value is ‘undefined’, (default), then the element will be visited by the FIA and executed. If this attribute has a value other than ‘undefined’, then the element will not be visited until explicitly set to 'undefined', by use of the clear element.
modal	Data Type: (true\|false)	Default: Optional (false)
	The modal attribute is a Boolean value that allows fine grained control of active grammars within the field. When the modal attribute is set to false (default), then all higher scoped grammars are enabled, (i.e., form-level document/dialog scoped grammars) while a user is within the field. If the modal attribute is set to true, then only field grammars are enabled and all other grammars are temporarily disabled.
name	Data Type: NMTOKEN	Default: Optional
	The name attribute defines the ECMAScript variable name that declares the field-item variable for the dialog. A successful grammar recognition will hold the resultant value in this namespace when executing any filled elements. Each field name within a document must be unique, else a fatal error.badfetch will be thrown.
slot	Data Type: NMTOKEN	Default: Optional (defaults to <i>field</i> name if unspecified)
	The slot attribute specifies the name of a grammar slot which is used to populate the field item variable. If no value is specified, then the interpreter will assume it to be the same as the field name. The slot attribute allows the developer to reuse slot/value grammar constructs in multiple fields whose names differ from one another.See the grammar documentation for further information.
type	Data Type: CDATA	Default: Optional
	The type attribute can specify any of the platform-defined built-in grammars. The Nuance browser offers support for all built-in grammars defined in the w3c specification. Note that no additional grammar constructs are needed within the field when a built-in type is specified, although any document or dialog scoped grammars will still be considered active. See the documentation for the built in grammars for further information.

Hello grvshr,

As these logs are quite obviously from another platform, I would have no way of deciphering them at all. I can say that the sample code that is listed in our documentaion set does work fine on the Voxeo platform.

I suspect that the getVocal platform is likely not a vxml compliance certified platform, which can cause problems when migrating code:

http://www.voicexml.org/platform_certification/certified_platforms.html

If you'd like to try this code on the Voxeo network, and send us in some specific code details, i would be happy to assist, however.

Hi Jorge,

At a glance, I can't see anything wrong with your script. However, real time debugger logs would be extremely helpful to troubleshoot this issue. All you need to do is call into your application with the real-time debugger window open. When you are able to reproduce the error and capture the logging for it, please submit the results to us via the "support" tab at the top of the debugger page. With this in hand, we will be able to troubleshoot much more effectively.

Best,

Hey there,
Is there a built in grammer for decimal numbers?
e.g I worked 5.4 hours today

Well I probably didn't even really work that much, having too much fun with this voicexml thing but hey, don't tell my boss.

Thanks,

Hello Simon,

While we do not have built in grammars for decimals at this time, we do have samples of other grammar types that can be modified to suit your needs. On the evolution site you will see the link to http://evolution.voxeo.com/library/grammar/library.jsp this zip file contains a few sample grammars that will enable you to tweak, or at least give reference in creating your own grammar.

We hope this helps.

Hi,

I need to take dtmf-star and dtmf-pound inputs from user.
Can you recommend, which field type i should take?

I also need to make a functionality in which during the questionnaire (on different levels), at any time user can press pound key to <reprompt> (on sub level menu) questions again or Press the star key to restart from top level menu.

Suggest me a good option.

please guide me.

Thanks.

1/15/2007 10:18 AM (EST)

Hello,

The reason that it is not working, is that you would need come type of grammar to accept input from a user. In your case, you have no field type (built in grammars), and no grammar specified by tag. <grammar>

To choose the right field types I would reccomend reading the below link. It is a description of each field type and what it does.

http://docs.voxeo.com/voicexml/2.0/gslbuiltins.htm#start

Also, for jumping around to specific areas of your document, I would recommend getting familiar with the <goto> command. Found here http://docs.voxeo.com/voicexml/2.0/gslbuiltins.htm#start

Let me know if you have any questions after reading through these.

Thanks

How do you test true/false for a boolean type field in its filled tag? Do you compare to 'yes' or to 'true' or what? Neither seem to work for me.

<field name="is_ready" type="boolean">
<prompt>Are you ready?</prompt>
<filled>
<if cond="is_ready=='yes'">
<prompt>Let's begin.</prompt>
<else />
<prompt>Okay. I'll wait.</prompt>
</if>
</filled>
</field>

MattHenry

1/31/2007 2:52 PM (EST)

In oder to test conditionals with the builtin "boolean" grammar, you do indeed test "true/false". However, you do it NOT as a string, (note: usage of the <log> statement for the lastresult$ return allows you to see exactly what any field returns. As such, I suggest the following in this case:

<if cond="is_ready== true">

Note the lack of single quotes around the value of "true".

Hi

With the built in 'digits' grammar you can specify length. Can you do this with letters and words? My aim is to speed up response times. Thanks

Regards

Daniel

MattHenry

3/15/2007 6:08 PM (EDT)

Daniel,

In order to do so, you would need to construct your own grammar, and specify that some rules are optional. For instance, assume the rulename "MY_ALPHA" will return one alphabetic character:

TOP_LEVEL_RULE [(
; 1-4 alpha characters
MY_ALPHA
?MY_ALPHA
?MY_ALPHA
?MY_ALPHA
)]

Check our subgrammar docs for additional information on this toopic.

~Matthew henry

danielvinson

3/15/2007 8:42 PM (EDT)

Hi Matt

Thanks for your prompt reply. I think I went a bit over the top asking about words of various length, I'm more concerned about returning a single character. Does this still require a top level rule or can I do something like so:

<field name="F_1" length=1>

Examples are much appreciated.

Regards

Daniel

jbassett

3/16/2007 7:42 AM (EDT)

Hi,

<field name="F_1" length=1> would not work as length is not an attribute of the field statement.

Just so everything is clear, you are trying to make an application that has a grammar that is looking to capture a single user utterance and assign a single letter value to it ? Could you please elaborate the exact logic behind your app ?

For instance are you trying to get the user to say a single letter and have it be recognized?

Thanks

2 questions

1. How cand I find out how many dtmf entries the user makes in a response.

2. Also I have a situation of the following:

<prompt>
Enter the stop id followed by the pound key. If you don't know, press # and I'll list all the stops ids for you
</prompt>

How do I allow the user use the pound key as an input and also allow the user to use it as a term char?

Hi there,

Allow me to address your questions one at a time:

Q: How cand I find out how many dtmf entries the user makes in a response.

[b]A: Here is a simple VXML script which makes use of the String.length javascript property, which will allow you to count the number of DTMF entries:[/b]

<?xml version="1.0" encoding="UTF-8"?>
<vxml version = "2.1" >
<form id="Form1">

<field name="F_1" type="digits">

<prompt>
Please press some digits, then press pound.
</prompt>

<catch event="noinput">
<prompt>
I'm sorry, I didn't get that.
</prompt>
<reprompt/>
</catch>

<catch event="nomatch">
<prompt>
Was that a number?
</prompt>
<reprompt/>
</catch>

<filled>
<prompt>
Thank you.
<say-as interpret-as="number" format="digits"><value expr="F_1" /></say-as>
</prompt>
<log expr="'Number of DTMF keypresses: ' + F_1.length"/>
</filled>
</field>
</form>
</vxml>

Q: Also I have a situation of the following:

<prompt>
Enter the stop id followed by the pound key. If you don't know, press # and I'll list all the stops ids for you
</prompt>

How do I allow the user use the pound key as an input and also allow the user to use it as a term char?

[b]A: Unfortunately, this is not possible. You simply cannot have the pound key as a DTMF input and the termchar. For this, I would suggest changing the termchar property to something different, or changing the "press # and I'll list all stop ids" to "press * and I'll....".[/b]

can it be achieved by building a special grammar file?

You can certainly specify a grammar file that lists dtmf-pound as a valid input, but I don't think you can have it as both an input AND a termcharacter.

hello,
i need to ask about the time gap for the input.i.e, when the field is executed it waits for a time period before it collects the input.for example if i have a field element which takes in a pin code of type digits and say the length is 8 then after entering the 8 digit number it takes some time to execute the filled element.What i wanted to ask is can I alter this time gap?hope my question is clear.please respond asap!!!

Thnx
Rishvi

voxeojeff

4/11/2008 11:20 AM (EDT)

Hello Rishvi,

If you have something like <field name="XXXXX" type="digits?length=8">, theoretically the filled processing time should be very minimal (~.25s). You *can* alter this, if you wish, by manually setting the "completetimeout" property. Per our VXML documentation,
[color=blue]
"The 'completetimeout' property specifies the length of time after a user utterance where the interpreter will consider the utterance complete. Changing the default value of '.25s' upwards offers more reliability in catching a user's complete utterance, at the cost of sacrificing response time. This property will only be active when set to a lesser value than the incompletetimeout property."
[/color]
That being said, you may set this property by specifying <property name="completetimeout" value="?"/> where '?' is the value you specify.

Hope this helps,

Jeff

4/17/2008 9:15 AM (EDT)

Hi Rishvi,

You can put in in a couple places depending on the scope of what you would like to change:

If you put it under the <vxml> tag and before your first form it will have the effect of being global for all your forms in that document. If you put in under the <form> tag it will only be used inside that form. Once you leave that form, it will go back to the default.

Here is an example:
<?xml version="1.0" encoding = "UTF-8"?>
<vxml version="2.1">
<property name="completetimeout" value=".50s"/>
<form>
<block>
<field name="guess">
<grammar type="text/gsl">
[one two three four five six seven eight nine]
</grammar>

<grammar type="text/gsl">

</grammar>
<prompt>
<audio src="audio/1.wav">

Now, the problem is the time gap between the user typing the alphabet and repeating that alphabet.For alphabets like 'r' ,'s','z' ...it's instant but for others like 'a','d' the time gap is more,the user had to wait for 4 or 5 secs.So How can i cut down that time gap??.

Please reply asap.It'll be of great help.

Hi Rishvi,

You can try setting the incompletetimeout property. It looks like this:

<property name="incompletetimeout" value=".5s"/>

Here are the details for incompletetimeout:
Details: The 'incompletetimeout' property allows you to change the setting of when, after a caller pauses in mid-utterance, the interpreter will start to process said utterance. After the period of time specified, (2s default), the interpreter will process the utterance and return either a valid grammar match, or a 'nomatch' condition.

You can find more about all the properties at this link:
http://docs.voxeo.com/voicexml/2.0/w3cprops.htm#start

The one thing that you have to be careful is that if the caller means to enter 'v' and they pause a bit after pressing 8 8, it will be taken as 'u'. So it may take some tuning to dfind out what is too short of a delay versus too long a delay.

Another tactic that I have seen people use is to use the pound sign as a terminator. So the caller would press 8 8 # and the '#' would stop the ASR engine from gathering any more information, and the grammar would just return 'u'.

If you have any questions, just let us know.

Thanks,
Jeremy Richmond

Hi there,

I am not totally clear on what it is that you are asking, as your question didn't have much in the way of explicit details. How I am reading this is "how can i make sure that the user utterance matches one of the two values defined in the 'timings' variable?"

If this is correct, then I would think that the following actions would be required:

1 - Use client side scripting to break up the string into 2 separate values: I would think that either the 'slice' method, or perhaps the 'split' method would be a good start:

2 - Use conditional logic within the <filled> section of your code to validate whether or not the user utterance matched one, or both of the values within variable name 'timings'

Hope this helps out,
