VoiceXML

• "Logic" can be implemented in multiple ways
• logic of grammar
• grammars or menu
• if statements
• script
• variables (assign, etc.)
• Ways we aren't covering server-side program

VoiceXML is

• an XML language, but very different from XML used
  for holding data in a structured way.
• Very close to a procedural programming language
• Forms are set up with grammars or equivalent and
  indications of what to do when grammar(s) is
  satisfied or not

VoiceXML

• 'human-like' behavior, namely conversation
• directed speech recognition and
• speech synthesis
• Artificial intelligence sometimes defined as
  'surprisingly human behavior'

not so good example

• Today I called American Airlines Advantage
• Voice asked me for my AA (frequent flyer) number
• Confirmed it
• Directed me to agent who
• Asked me for the number again (sigh)
• (very good service)

VoiceXML

Project II

• This is a classan opportunity to learn!
• Consider doing something different, perhaps
  creating a (pilot) application for a real
  function not your own.
• It is up to you.

  'bullets'.
• Function, audience
• Prepare presentation
• Function, audience, way to assess success, plan
  for work (including what the difficult part is)
