Method of automatic processing of a speech signal |
摘要 |
Method of automatically processing a speech signal which comprises the steps of: determining a sequence of probability models corresponding to a given text; determining a sequence of acoustic strings corresponding to the diction of the given text; aligning between the sequence of acoustic strings and the sequence of models; and determining a confidence index of acoustic alignment for each association between a model and an acoustic segment. Each determining step of an alignment confidence index is carried out at least from a combination of the model probability, a priori model probabilities and the average duration of occupancy of the models. |
