User Interface - Natural Language User Interface

This kind of interface seeks to allow you to instruct the computer simply by talking to it. This is called "Natural Language Interface"

The ideal concept of a natural language interface is for you to say something like "Computer - Open the last document I used" and machine would carry out the task - no pointing, clicking or typing!

Voice-activated interfaces are now appearing in cars.

It needs a very specific, carefully spoken commands so, there are difficulties

Examples:

- People speak differently with accent, language etc
- Language is often ambiguous
- Understanding speech in a noisy environment is difficult.
