Researchers devote considerable attention to allow non-written human-computer interactions (e.g., speech, graphics)

• Recognition of speech allows oral communication
• Difficulties related to accents, pitch, diction
• Most successful when application domain is limited or only one primary user
  • Amtrak uses automated system for telephone-based information and reservation system.
  • Dragon Naturally Speaking improves its transcription of speech, based on speech samples/training from a specific user, a review of user files to determine common word choices of a user, and on experience regarding past words used.
• Success of these systems typically mixed, but improving

Rather few attempts for one system to cover a wide range of applications,
BUT range of applications continually expands.

Current technology is far from passing the Turing Test
