Abstract:
A method for modelling a sound in at least two languages, comprising the steps of:(a) identifying a first feature vector for a first spoken sound in a first language;(b) identifying a first hidden Markov sound model, from among a plurality of standard Markov sound models in a Markov sound model library, which most closely models said first feature vector;(c) identifying a second feature vector for a second spoken sound, comparable to said first spoken sound, in a second language;(d) identifying a second hidden Markov sound model from among said plurality of standard Markov sound models in said Markov sound model library, which most closely models said second feature vector;(e) employing a predetermined criterion to select one of said first and second hidden Markov sound models as better modelling both of said first and second feature vectors; and(f) modelling said first and second spoken sounds in both of said first and second languages using said one of said first and second hidden Markov sound models.
