<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>Although I’m not an active FS user,
I’ve been following the discussions for some time…I have some
previous experience with VXML (and even with SALT, if you still remember the
misguided attempt by MS to highjack the standard…). Here are some
thoughts:<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:

<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>VXML was created mainly for speech
applications, i.e. ASR and TTS. It comes with quite a bit of overhead, which,
in my opinion, is not justified for the “classic” IVR development.
Yes, the “big guys” use VXML, but many do so for reasons that are
more political than technical. If you are a big company, you simply can’t
“ignore open-standards”. A bit like the government…<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:

<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>Very few projects are developed
“directly in VXML”. Most use RAD tools that give a much better
programming environment, and actually “hide” VXML. <o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:

<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>In reality, very few projects rally care
about “vendor independence”. In fact, I’ve never heard of a
significant voice app ported from one VXML gateway to another...<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:

<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>In my opinion, the combination of
speech-rec engines, VXML gateways and RAD tools, because of all this extra cost
and complexity, does not fit well with the FS philosophy. So, unless there is a
specific requirement for speech-rec, the FS developers would be better off
using the great tools already available in FS.<o:p></o:p></span></font></p>

Well if it's for marketing reasons then maybe that's why FS should do it.<br>
After all, the idea is to get people to try something. Plus it is fast in<br>
making up a dialogue so someone can quickly test if this will work for what<br>
they want.<br>
<br>
In a previous post, Steve said many don't use it but Voxeo Forums do have<br>
posts daily on vxml. Maybe it's the first-timers getting their feet wet.<o:p></o:p></span></font></p>
