ONE
Human
Factors and Voice Applications
By
Ed Halpern
So
it's 2001 and most VoiceXML applications do not quite
sound like Space Odyssey's Dave and HAL. But there have
been giant leaps in speech recognition technology and
voice services over the last several years. While the
computer has not attained the sophisticated processing
power of a human, if you understand the rules of user
interface design and you know the limitations of the
technology, you can create effective human-machine speech
dialogues.

TWO
User-Centered
Deisgn for VoiceXML Applications
By
Mike
Farley
As
a growing audience is exposed to VoiceXML solutions,
will people use your applications while they quickly
abandon others? Part of the answer to that question
depends on how you address human factors issues during
application design and development. Your VoiceXML application
can avoid or address these issues - and retain more
first time users - by implementing human factors wisdom
in the context of a UCD (user centered design) process.

Turning
GUIs into VUIs: Dialog Design Principles for Making
Web Applications Accessible by Telephone
By
Bill Byrne
There's
no question that the compatibility of VoiceXML with
the familiar and ubiquitous web infrastructure has greatly
simplified the implementation of speech recognition
applications. Instead of a PC, you can use a telephone;
instead of HTML, you can use VoiceXML; instead of a
web browser, you can use a "voice browser"
(or VoiceXML interpreter). It follows, then, that a
reasonable way to develop voice applications is to simply
translate web pages into "voice pages", right?
Wrong. As we'll see in this article, good VUI design
starts with a solid understanding of the most important
differences between GUIs and VUIs and ends with the
application of linguistic and social principles to the
overall development effort.
