1. An image manipulation apparatus comprising: means for reproducing an image; a speech recognition user interface for allowing a user to input a speech signal comprising a description of a desired change to be made to the reproduced image; means for interpreting a recognition result output from the speech recognition interface; and changing means responsive to the interpreting means for changing the colour of one or more parts of the reproduced image in order to affect a manipulation desired by the user; wherein said description comprises a number of continuously spoken words; wherein said speech recognition user interface comprises: a memory for storing a plurality of reference word models, each representative of a word, and for storing a language model which defines sequences of the reference word models which can be matched with the input speech signal, in order to define input speech commands; matching means for matching the input speech signal with selected sequences of said word models, selected in accordance with the stored language model; recognition means, responsive to said matching means, for providing a recognition result based upon a likely sequence of reference models that corresponds to an input utterance; receive means for receiving a new input speech command comprising two or more whole words; means for generating a word model for each of the words contained within the new input speech command, if they do not already exist; and means for adapting said language model to incorporate said new input speech command.
