Abstract
The present invention relates to a method and arrangement for speech to text conversion. A string of phonemes is identified from a given input speech. The different phonemes are identified and are joined together to form words and phrases/sentences. The words are checked lexically, any words which are not found in the language concerned being excluded. The phrases/sentences are checked syntactically, any word combinations which do not occur in the language concerned being excluded. A model of the speech is obtained by the process. The intonation patterns of the model and of the input speech are determined, and compared, the words and phrases/sentences of the model, whose intonation patterns do not correspond with those of the input speech, are excluded from the model. A representation of the words, and/or word combinations, which best corresponds with the input speech is then provided, preferably in the providing in the form of a print out of the related text.
