Abstract
An acoustic model adaptation system includes a memory device and a model selector engine coupled to the memory device. The model selector engine is configured to compile information of environmental conditions to identify a current speech environment for audio input into a speech recognizer on a device. The model selector engine is further configured to compare the information of the environmental conditions with profiles of acoustic models. Each profile associates with an acoustic model. Each acoustic model compensates for background noise or acoustical distortions of the audio input. The model selector engine is further configured to select a first acoustic model for the speech recognizer based on the information of the environmental conditions exclusive of audio input from the user.
