Abstract
A method for performing speech recognition of a user's speech includes performing a first speech recognition process on each utterance of the user's speech, using acoustic models that are based on training data of non-discrete utterances. The method also includes performing a second speech recognition process on each utterance of the user's speech, using acoustic models that are based on training data of discrete utterances. The method further includes obtaining a first match score for each utterance of the user's speech from the first speech recognition process and obtaining a second match score for each utterance of the user's speech from the second speech recognition process. The method also includes determining a highest match score from the first and second match scores. The method further includes providing a speech recognition output for the user's speech, based on highest match scores of each utterance as obtained from the first and second speech recognition processes.
