11. A system comprising: a processor; and a computer-readable storage medium having instructions stored which, when executed by the processor, cause the processor to perform operations comprising: starting a current automatic speech recognition session for recognizing speech received from a user via a device; identifying a group of speech recognition models comprising a speaker independent model and a speaker dependent model; recognizing the speech via each model in the group of speech recognition models, to yield recognition results; selecting, based on the recognition results, a dominant speech model from the group of speech recognition models to yield a remainder set of dropped speech recognition models; and continuously using only the dominant speech model, without applying the remainder set of dropped speech recognition models, to recognize additional speech received from the user.
