11. Natural Language Interface

Advantages and Disadvantages
Advantages	Disadvantages
The user does not need to be trained in how to use the interface	Reliability remains an issue - the interface can only respond to commands that have been programmed
More flexibility than a dialogue interface	Highly complex to program and so only warrants this kind of interface where other types of interface are unsuitable
Suitable for physically handicapped people	Not widely available as other forms of interface are often superior
	A voice interface might need training in order to get the software to recognise what the user is saying
