Hi everyone, Did someone ever try and implement a VXML interface on freeswitch? Or do you think it's a good idea? Or not? Since it is an actual standard, I guess there might be a market for application service providers. Remko

To the best of my knowledge no one has created an interface for this. I'm sure one will be created if and when the market demand gets high enough.

Great Idea.
Try setting up the exact same dialogue with say Voxeo's VoiceXML system and then with Javascript/Lua and pocketsphinx. It's an order of magnitude faster with VoiceXML.
I don't know went demand will pick up for VXML on FS but one issue that I think will block it is how robust the FS embedding of pocketsphinx is to the harsh noisy enviroment of telephony.
Currently, it lacks this "robustness" compared to vendor products but once that happens then more will want to use it and VXML will become more in demand ... hopefully.

FreeSWITCH has a generic ASR interface to plug into any asr engine. The quality of the integrated free asr has little to do with VXML. If you want more robust asr, you will likely need to pay for it.

I was initially turned off by VXML when it came out because the first way they tried to make money off it was to
sell the clients that let you build the actual xml.  I was not really motivated to pay money to be able to
just generate xml just so i could code a free server for it so I lost interest.

I did hear there is now finally a free one out there. so that may make it a little more reasonable.

I've commented in the past that I'm totally open to supporting VXML but we have never had the public interest, time or resources
to work on it thus far.

Isn't ASR optional in VXML?

Directly in vxml.

You can use VXML without ASR, but ASR and TTS are both required parts
of the specs.

I agree that the original commercial model used for VXML gets in the way of it's own success. It's also focussed way too much on ASR/TTS. I think we can all agree this technology is still a future promise, even after 10+ years. But technically VXML is an interesting concept, especially together with related standards like ccxml (dave@3c.co.uk (dave@3c.co.uk)> wrote: On Tue, 2009-04-21 at 14:35 -0400, mszlazak@aol.com (mszlazak@aol.com) wrote:> Great Idea.> Try setting up the exact same dialogue with say Voxeo's VoiceXML> system and then with Javascript/Lua and pocketsphinx.

I ask because VoiceXML strikes me as being a bastardabomination of the highest order, whose sole saving grace is thatit's a standardised bastard abomination.Or is Pocketsphinx the problem?Cheers --Dave _______________________________________________Freeswitch-users mailing listFreeswitch-users@lists.freeswitch.org (Freeswitch-users@lists.freeswitch.org)MSN:anthony_minessale@hotmail.com ([email]MSN%3Aanthony_minessale@hotmail.com[/email])GTALK/JABBER/PAYPAL:anthony.minessale@gmail.com ([email]PAYPAL%3Aanthony.minessale@gmail.com[/email])IRC: sip:888@conference.freeswitch.org ([email]sip%3A888@conference.freeswitch.org[/email])googletalk:conf+888@conference.freeswitch.org ([email]googletalk%3Aconf%2B888@conference.freeswitch.org[/email])pstn:213-799-1400

For compliance it's needed to support it, but it's not actually needed
to make a working application. You can just use wave files like this:

<form id="MainMenu">
<block>
<audio src="helloworld.wav"/>
</block>
</form>

Voxeo actually has a nice set of tutorials and reference material on it:

VXML is not only interesting but required concept.
I'm not talking about VXML itself, but presence of specification. I still remember my confusion, when initially thinking about media and call control dialogs and interfaces I found out XML based languages such as VXML and CCXML.
Nevertheless VXML clearly defines media dialogs: entities, state machines and transitions, which is just good.
More over VXML 3.0 is under the way
http://www.w3.org/TR/vxml30reqs/
If you check the authors list, it will be clear this is going to be another standart we should live with.
3.0 is rework of 2.1 version, added native support of audio/video dialogs, speaker identification/verification.

FreeSWITCH as a platform is almost ready for that, what it is still missing is VXML interpreter itself.

The latter supports call transfer and conferencing. Every VoIP and TDM
product I've worked with in the past has it's own application interface
or is bound to an interface that's tailored for a special use (like
pbx). I've also used voxeo's callxml, that's implemented with the
CosmoCom ACD product. It's implementation is crappy, but the concept is
nice. The idea of separating callcontrol+media (voice/swithing core) and
application+ivr logic (vxml webserver cgi scripts) sounds rather
appealing to me.

Do you known the name of the free VXML editor/client that's out there?

I've used vxml on Voxeo's system and it's really nice to work with. "Underneath" it's tags is Javascript so a FreeSWITCH with a fast TraceMonkey engine and vxml would be great. Your MRCP project would help connect things to other ASR/TTS systems if pocketsphinx isn't good enough. Nice package.

If you don't like vxml then here is a post on voicePHP

http://www.speechtechblog.com/2009/04/22/voicexml-to-go-down-in-the-third-says-voicephp

It's from a vendor but there might be some good ideas to get from what they
are doing.

FreeSWITCH needs demand to get vxml and it's not there yet. For now, it
looks like the FS community is waiting for demand instead of trying to
create it.
