Abstract:
1. A lexical stress prediction system for receiving data representing at least part of a word and outputting data representing the position of lexical stress of the word, the system comprising a plurality of stress prediction model means for finding matches between model data and received data, the plurality of model means comprising: a first model means for receiving the received data and searching for a match between the generated model data and the received data, and if a match for the received data is found, outputting prediction data representative of a prediction of lexical stress corresponding to the received data; and a default model means for receiving the received data if no match is found in any other of the plurality of model means, and outputting prediction data representative of a prediction of lexical stress corresponding to the received data, wherein the first model means is an automatically generated first model means which is trained automatically using a dictionary with phonetic transcriptions and primary stress as a training corpus by searching the words of the dictionary for possible affixes and determining the affixes which correlate with the position of primary stress in the words, the first model data comprising affixes stored with stress and priority information the system being configured such that when more than one match is found by the first model means of the received data the prediction data output corresponds to the lexical stress prediction with the highest priority.
