Dear
Readers,
The amount of activity in the industry that is centered
on the VoiceXML 2.0 and related specifications is enormous.
In terms of platforms alone, Ken Rehor’s
World
of VoiceXML website, lists over 40
VoiceXML platforms.
In this issue we bring you up close to a couple of VoiceXML
implementations.
In his article entitled
“The VoiceGenie VoiceXML Platform Solution”
Rob Marchand gives us a first
hand look at the VoiceGenie VoiceXML platform. The VoiceGenie
platform’s broad support of various off-the-shelf
ASR and TTS technologies makes it a very attractive
choice particularly in terms of flexibility and language
coverage. Rob also appears again in this issue in his
regular columnist role. This month’s
First Words
column brings together all the “theory”
on VoiceXML events that have been presented in the previous
two columns, by way of concrete code examples.
In
“The Motorola VoxGateway: Lessons Learned”,
Jim Ferrans shares some of the legend and lore behind
the Motorola VoiceXML implementation. The Motorola VoiceXML
browser has been integrated into a number of commercially
available VoiceXML platform offerings, and in this article
Jim shares some of the lessons learned along the way.
Of particular interest is a detailed look at how the
browser’s unique architecture and the use of Java
as the implementation language have made it very easy
to integrate and port across operating systems, and
at the same time provide blazing fast performance. If
you are implementing a VoiceXML browser, or about to
implement one, this article is definitely a must read!
Have you ever wrestled with how to add fast forward
and reverse functionality during audio playback in your
VoiceXML application? After all, this is a standard
feature in most voicemail systems. And by the way, the
solution better not rely on any platform-specific features
and/or warts! In the Q&A department this month,
Matt Oshry’s
Speak and Listen column presents
a rather clever server-side solution to this problem,
utilizing the ubiquitous sox
utility. They don’t
teach you this stuff in school!
Sincerely,
Jonathan
