Creating interfaces

• XML XSL review
• VoiceXML grammar
• Homework postings, presentation, study guide

2
XML

• General format for data. Intended for use between
  people and applications and between applications
  and applications.
• XSLT language (itself XML format) for
  transforming XML,
• one use being XML to HTML. The resulting HTML
  can use JavaScript.
• XML to WML
• XML to VoiceXML (probably less common, but this
  use could grow)

3
XML

• Used server side with php or asp or ColdFusion
  or older technologies cgi/perl
• Used with/by Flash
• Used client side by JavaScript
• Used with 'Web services'

Preview

• Next Fall, new course on Java and connections
  (title not set)
• Peter Ohring
• probably evening
• upper-level math/cs elective

XML

• format for holding content (independent of
  formatting and use)
• Not the only one! Consider
• relational databases
• linked lists
• general graphs (nodes with any number of links,
  possibly cycles)
• ?

"XML Languages"

• XSLT
• WML
• VoiceXML
• There are now also XML specifications for books,
  purchase orders, math, etc.

VoiceXML Grammars

• Use / study grammars in Tellme studio
• Note GRXML, alternative form of grammar that is
  an XML format will probably replace GSL,
  currently used by Tellme
• Look up bargein, n-best
• Specifying numeric keys dtmf
• Setting multiple values

8
Grammars

• Parentheses indicate and (sequence of words)
• Square brackets (within an option) indicate or
• ? Indicates optional zero or 1 occurrence
• indicates any number of occurrences
• indicates one or more occurrences
• (math ?(computer science)) accepts
• math
• math computer science
• purchase pace accepts
• purchase
• pace

9
Questions

• Give a grammar that accepts "Tom", "Dick", or
  "Harry"
• Give a grammar that accepts "Bill Clinton",
  "Hilary Clinton", "President Clinton"
• Give a grammar that would distinguish between the
  41st president and the 43rd president.

10
DTMF

• The grammar mode default setting is both voice
  and dtmf.
• dtmf-1 means to accept caller hitting 1 key
• Use grammar tools in My Studio for help
  generating the keys to represent letters

Letter correspondences

• In My Studio, click on Grammar Tools and then
  DTMF and the system will generate sequences (and
  let you know if there are problems)
• Here are 3 letter sequences for these two
  choices
• dtmf-6 dtmf-2 dtmf-8 math
• dtmf-6 dtmf-3 dtmf-9 new media

13
Setting multiple values

• (math ?computer) ltmajor math"gt ltbuilding
  NS"gt
• (new media) ltmajor nm"gt ltbuilding Music"gt

• MyStudio 1-800-555-VXML You need to give 5
  digit plus 4 digit pin

  turn in (hardcopy) description and,
• if you are doing VoiceXML, your URL
