<p>Statistical speech models are used to improve the recognition rate of automatic speech recognition systems. The inventive method makes it possible to construct speech models with small volumes of text or without a text. Linguistic classes are formed and the speech model, i.e. an a-priori probability of word sequences, is determined based on the grammatical structure of the text and depending on the vocabulary of the text. Set probabilities for words and for linguistic classes are determined for this purpose. In addition to creating a new speech model for a predetermined area of application, the inventive method also provides a means of adapting a pre-existing speech model to a new area of application.</p> |
