Minimum error rate training of combined string models

Abstract From the Canadian patent

A method of making a speech recognition model database is disclosed. The database is formed based on a training string utterance signal and a plurality of sets of current speech recognition models. The sets of current speech recognition models may include acoustic models, language models and other knowledge, sources. In accordance with an illustrative embodiment of the invention a set of, confusable string models is generated each confusable string model comprising speech recognition models from two or more sets of speech recognition models (such as acoustic and language models). A first scoring signal is generated based on the training string utterance signal and a string model for that …
