Artificial language generation and evaluation
First Claim
1. A method of automatically generating candidate artificial-language words, the method involving a process that is specifically set to favour artificial-language words which are more easily correctly recognised by a speech recognition system and have a familiarity to a human user.

Abstract
A method is provided of generating an artificial language for use, for example, in human speech interfaces to devices. In a preferred implementation, the language generation method involves using a genetic algorithm to evolve a population of individuals over a plurality of generations, the individuals forming or being used to form candidate artificial-language words. The method is carried in a manner favouring the production of artificial-language words which are more easily correctly recognised by a speech recognition system and have a familiarity to a human user. This is achieved, for example, by selecting words for evolution on the basis of an evaluation carried out using a fitness function that takes account both of correct recognition of candidate words when spoken to a speech recognition system, and the similarity of candidate words to words in a set of user-favourite words.

26. A method of evaluating words of an artificial language in respect of their usage as a spoken human language for a man-machine interface, the method involving applying a fitness function to each artificial-language word where said fitness function comprises a combination of:
-
a measure of the ease of correct recognition of a candidate artificial-language word when spoken to a speech recognition system; and
a measure of the similarity of a candidate artificial-language word to any constituent word of a set of reference words as measured by a speech recognition system to which said word is spoken.
