7-4 For the Senses
FOR ALL THE SENSES
Technologies that will help you work with
information in various forms that appeal to all the
senses. These technologies include:
Automatic Speech Recognition
7-5 For the Senses
3-D - TECHNOLOGY FOR REAL
THREE-DIMENSIONAL (3-D) technology
presentations of information give you the
illusion that the object you抮e viewing is
actually in the room with you.
Real 3-D technologies extend beyond pseudo
3 dimensions that you see in software such as
It抯 really only a matter of time before 3-D
technologies become commonplace.
7-6 For the Senses
RECOGNITION (ASR) SYSTEM
not only captures spoken words but also
distinguishes word groupings to form sentences.
Beware - ASR differs from automatic speech
For example, what does, 揊ruit flies like a
We have a long way to go before computers
really understand what we抮e saying within the
context of a paragraph or conversation.
7-7 For the Senses
STEPS IN ASR
1. FEATURE ANALYSIS - eliminates other noise
and converts the digital signals of your speech
into phonemes. See Figure 7.5, page 267.
2. PATTERN CLASSIFICATION - attempts to
recognize your spoken phonemes by locating a
matching sequence among words stored in an
acoustic model database.
3. LANGUAGE PROCESSING - makes sense of
what you抮e saying by comparing the possible
word phonemes with a language model
7-8 For the Senses
TYPES OF ASR SYSTEMS
DISCRETE ASR - requires you to pause
between each spoken word.
CONTINUOUS ASR - processes continuous
streams of words - that is, normal speech.
SPEAKER-INDEPENDENT ASR - can be
used by anyone, but have limited vocabularies
that cannot be expanded.
SPEAKER-DEPENDENT ASR - lets you 搕
rain?it to recognize your voice. These have
expandable vocabularies but can be used only

WHAT IT WILL TAKE FOR ASR
TO BECOME STANDARD
Greater storage for an expandable vocabulary
Better feature analysis to support continuous
More dynamic language models to support

advantage of multimedia to publish items such
as books and magazines in an electronic
format rather than in the print-on-paper format
associated with traditional publishing

applications are not inexpensive to develop) and
creativity. Then, follow these six steps.

5. Testing and documentation
7-13 For the Senses
1.ANALYSIS - Identify (1) the subject matter, (2)
target audience, (3) setting, (4) why
multimedia, and (5) other needed developers.
2.DESIGN - Develop content by creating
STORYBOARDS (a visual representation of
your multimedia objects) and define the
navigation methods (including linear, menu,
hierarchy, network, and hybrid). See Figures
7.9 & 7.10 on pages 275 & 276.

special forms of media - usually sound and
7-15 For the Senses
5.TESTING AND DOCUMENTATION - allow
users to experiment with the application and
make changes as necessary.
6.DELIVERY - place multimedia application on
some type of storage device, usually CD-ROM
because of its durability and ample storage
