IBM Interface Projects:

The IBM Corporation has initiated a variety of natural language
and voice recognition projects, including:  

Tangora: recognizes and responds to 20,000 words of human speech;

Newselector: natural language processing to help the computer
understand text and provide intelligent archiving and retrieving;

Translator: English to Spanish or Chinese; translation systems
require particular sensitivity to language context because of
colloquialisms and idiomatic expressions;

Paper-like interface: recognize handwriting entered on a
digitizing tablet (Rogers, 1988).
