Tutorial: VoiceXML Hello World Phone Application

This simple tutorial will step you through the creation and deployment of a "hello world" application. When we're done, you'll have a basic understanding of creating phone applications using web technologies, and you can call the resulting Hello world application.

Step 1: Write the Main VoiceXML File

Open up your favorite text editor to write a few lines of VoiceXML.

First you'll need to put in the file a standard XML header. Every XML document you write, including VoiceXML documents, will need a header like this.



<?xml version="1.0" encoding="UTF-8"?>

Next, you will need to specify the proper version number for your VXML document. If you plan on using any of the newer 2.1 application features, such as the <data> element, then you will want to make certain that you specify version "2.1".



<?xml version="1.0" encoding="UTF-8">

<vxml version="2.1">



</vxml>

Since we are starting small, we will partake in the time-honored tradition of true 'Hello World' applications.



<?xml version="1.0" encoding="UTF-8"?>

<vxml version = "2.1" >



  <form>

    <block>

     <prompt>

      Hello World. This is my first telephone application.

     </prompt>

    </block>

  </form>

</vxml>

That is all there is to it. Notice that even at this most basic level of scripting, we still see evidence of some required code structure. The <form> tag is not unlike the HTML <form> tag, as it groups sections of input and output together on your page (remember, this is just a "web page" for the telephone). But the similarity between the two tags ends there -- in more complicated scripts the <form> can also serve as a named section that can be jumped to (not unlike a HTML anchor tag). In a similar way, the <block> tag in our example seems somewhat unimportant because we are performing but a single function; however, VoiceXML requires structure inside the <form> tag, which is what the <block> provides for us. So how does VoiceXML know to convert "Hello World. This is my first telephone application"? No extra tags are required to read text-to-speech -- VoiceXML assumes any non-tagged value is text to be read over the phone. How simple is that?

Your VoiceXML file is now done. Go ahead and save it as "helloworld.xml".

Step 2: upload your VoiceXML file to the web

Next you need to post or upload your VoiceXML file to a web server. In this example, we might put the file into http://www.myserver.com/helloworld, so that your VoiceXML file would be at http://www.myserver.com/helloworld/helloworld.xml in the VAM. If you don't have access to a web server, you can use the new Voxeo File Manager to upload your code to our servers. As a member of the Voxeo Community, you get 10MB of free hosting space on our servers in which to test your applications. See our How-To Guide on the Voxeo File Manager for more details.

Step 3: sign up for a voxeo account

If you have already signed up for a voxeo account, you can skip forward to the next step.

Signing up for a Voxeo account is absolutely free. The link below will pop-up a new window where you provide basic contact information to sign up for an account. When you're done signing up for an account, just close the pop-up window and return here to move on to step 5.

Click here to sign up for a voxeo account

Step 4: link a phone number to your VoiceXML URL

Not sure how to map an application to a phone number? Check out the Quick Start Mapping Guide for info!

Step 5: upload, and call your application

You are now ready to try out your application. Call the number you received in step 4. You should hear "hello world" read to you over the phone!

Hello Diogo,

I see you have already created an Evolution account, therefore, all that is necessary is to point your .war file to your external server which will support and execute this file.

This can either be as a StartURL in Evolution or a route in a local installation of Prophecy. As we do not allow any server-side components in our staging environment, you will need to point the URL of you .war file to external web server which can execute this.

In the instance of a local installation of Prophecy, built in support exists for php/jsp exists, and you will need to place your scripts in the \webapps directory. So the route you specify for your .war file must be direct there as well.

Hope that clears things up a bit, but if you have any additional questions or concerns please feel free to let us know.

Best Regards,

Brian Lehnen

Can we have nested form ?

voxeojeremyr

6/30/2009 10:16 AM (EDT)

Hello,

No you cannot nest Forms, they are meant to be standalone entities. The only valid parent of <form> is <vxml>. If you give us an idea of what you would want to nest forms for, I am sure we can come up with a solution that would fit your needs.

how is Voxeo's voice browser able to interpret an .xml file when VoiceXML files must have a .vxml extension?

dpinter

8/5/2009 5:36 PM (EDT)

what is the purpose of the pin? does it redirect you to the specified server?

VoxeoDustin

8/5/2009 5:42 PM (EDT)

Hello,

The VoiceXML browser does not look at MIME type or file extension, but rather looks at the XML header in the file and for the <vmxl> element to determine it's the proper type. This allows us to use non-standard file extensions as well as server-side - it will still parse a .php file as a VoiceXML file and as long as the output it valid VoiceXML(like your web browser is with HTML), it does not care.

In regards to the PIN question, I assume you are referring to the PIN you enter in the 800 PIN application. This PIN is the DNIS(the dialed number) attached to the application and is used to route to the appropriate application in our hosted environment.

Hello,

I have just tried my first application and it worked really well. It was successful at my first attempt and I give you guys a big thank you.

Now, I have a few questions. I am doing this work at my brother's house and I do not want to accumulate any phone bill for him before I leave his place. Is any of these phone numbers we are given to call free? What about this one (800) 289-5570 then PIN: 9991436201? Another question, how can I use my own audio file?

Thanks,
Luis

VoxeoDustin

9/10/2009 6:16 PM (EDT)

Hello Luis,

The (800) 289-5570 then PIN: 9991436201 number is a free number to dial within the United States. If you're outside the US, you may want to dial in via the SIP address provided for your application via a SIP softphone.

Let me know if we can be of further assistance.

Hello,

You can use the provided U.S. based numbers, but you will probably incur long distance, international rate charges. There are also Skype numbers to use with a Skype client and iNum numbers for use with a Gizmo softphone. If you wish to use a SIP phone you can download X-Lite or SJphone for free.

Hello,

For your application I see you have the Start URL set as "helloworld.wav". You'll need this to be set to an XML file. You'll need to place any application files under the "www" directory. I see there is a Voice folder you created. Just create that folder under the "www" directory, and put your hello.xml file there.

Then in your application settings:

* Voice URL: file manager | edit file | view

Click "file manager" and select the hello.xml, click the Map button, and Update the application.

Hello,

Currently, the buttons in the application debugger are only active for the Prophecy 8 VoiceXML platform. When using this platform you will see your individual sessions in this box, which you can then click on and apply the applicable filters.

If you are indeed using this platform and still do not see the active sessions, please let us know.

Hi,

I looked great in the beginning but stopped working at all later. :(

In my first try, I built a new application for "Hello World" and then tried calling through SJPhone. It worked fine. However, on trying it later, it stopped giving any response. When I call from SJPhone now, it just keep on ringing & the vxml is not read at all.

Could you please help me understand the reason for such a behaviour?
Also, the debugger does not show any progress while the call is in process.

Thanks.

Hi

Is there way if I can access my VXML application through a number of my choice?
Problem is that I do not want to dial a USA number from India to access my application and Voxeo doesn't have a number in India.

I need to know how the VXML browser interacts with Telephony hardware?

Regards
Vineet

VoxeoDustin

12/1/2010 6:18 PM (EST)

Hello Vineet,

The easiest way to accomplish this is by simply dialing the Prophecy server using a SIP phone. For a local installation of Prophecy, you would just dial sip:address@prophecyIP, where 'address' is the address you created for your application and 'prophecyIP' is the IP address of the Prophecy server. If you're using our hosted platform, we provide a SIP address you can use to dial into your app under the Contact Methods section of your application settings.

If you wish to call your applications using a landline or cellphone, you can use an analog-to-SIP gateway to connect standard phone lines to the server. We recommend the Audiocodes MP-114 (four lines), MP-118 (eight lines) or Mediant 1000 (up to 24 lines).

Let me know if we can be of further assistance.

Cheers,
Dustin

I have prophecy 9 installed on my local machine. Now I want to test the application helloword.I want to know how to process.In which folder do I put the VoiceXML file? Which url I have to call via the sip phone to test the application.
Thanks for the help.

voxeoJeffK

7/22/2011 8:35 AM (EDT)

Hello,

First, we would recommend using Prophecy 10 rather than 9 since it includes additional functionality, and is a newer version. For setting up the application itself, and then calling it you can use our QuickStart Guide here:

Thank you Jeff !!!
the test is working properly. Now can I make an application in French because I use a trial version of prophecy.

VoxeoDante

7/25/2011 4:02 PM (EDT)

Hello Mozak,

If I am understanding your most recent post correctly, it sounds like you are asking if you can create an application in french using the trial version of Prophecy. This is possible, but the trial version of Prophecy does not ship with French language packs. You would need to get these packages and install them separately.

You also have the option of using the Voxeo hosted network which does have French available in the staging environment.

If you would like to continue working with your local installation of Prophecy for this, please let us know your applications requirements, and we can work with you to get the proper packages.

7/26/2011 12:44 PM (EDT)

Hello,

I noticed in your account that your "hello" application is correctly prompting French. For your local installation you would need to install French language packs. Since our Hosted environment is already configured successfully for French it may be more convenient for you to continue using your hosted account to develop further if desired.

Let us know though if you require trial French TTS/ASR for you local install.

Hello Infogain2011,

Sadly we are not able to provide numbers in India due to local regulations in that country which do not allow us to acquire numbers there. We are also not able to dial out to India from the US in the staging network.

You best option for testing would be to using either Skype or SIP to test as we provide both Skype and SIP inbound numbers for every application.

There is a lot to learn here. If you are interested in using VXML with .net, I would honestly recommend reading through the tutorials here. There are a number of things about VoiceXML that you will need to learn, and I do not think that I can pass along all that information in one posting.

Specifically for use with server-side like ASP, you would want to take a look here;

In regards to your questions on Prophecy, I think it is best to direct you here for additional information:

Hello,

Looking at your code everything seems to be good. In regards to your HelloWorld.java we would recommend that you declare the variables outside of the scope of your try catch as global variables as this will allow you to call them in more than one method. Additionally, you will not be able to reference these variables within the try catch if you don't declare them as global variables, outside the scope of the try catch.

Please feel free to contact us if you have additional questions or if you need further assistance.

Best regards,

Hello,

I am from Bangladesh and trying to implement a simple IVR application. But I'm failing to call my application as I don't reside in US or any other country provided in the list.

Is there any other way that I can emulate my app?

Hello,

While dialing your application from a standard phone is best to simulate standard calling conditions, being that you have a US based application you get a specific Skype number that you can call your application through. This number can be found under the "Contact Methods" tab and typically can be easily used by clicking on the number. As a warning, there are known issues with the integrity of using Skype in calling our hosted IVR applications, so if you have issues with Skype there is also a SIP VoIP number you can also call with your own web-enabled SIP phone.

Using one of these calling method in conjunction with the hosted debugger you can verify the validity of your application.
