In a distributed automated speech recognition (ASR) system, speech models may be employed on a local device to allow the local device to process frequently spoken utterances while passing other utterances to a remote device for processing. Upon receiving an audio signal, the local device compares the audio signal to the speech models of the frequently spoken utterances to determine whether the audio signal matches one of the speech models. When the audio signal matches one of the speech models, the local device processes the utterance, for example by executing a command. When the audio signal does not match one of the speech models, the local device transmits the audio signal to a second device for ASR processing. This reduces latency and the amount of audio signals that are sent to the second device for ASR processing.
