15. A non-transitory computer-readable medium storing software comprising instructions executable by one or more computers which, upon such execution, cause the one or more computers to perform operations comprising: receiving, by a given mobile device, audio data corresponding to a user utterance; while receiving the audio data corresponding to the user utterance, determining, by the given mobile device, that the given mobile device has changed position from a first pose to a second pose; in response to determining that the given mobile device has changed position from the first pose to the second pose, determining endpointing parameters for endpointing audio data received by a mobile device changing from the first pose to the second pose; using the endpointing parameters for endpointing audio data received by a mobile device changing from the first pose to the second pose, endpointing the received audio data; generating, by an automated speech recognizer, a transcription of the endpointed audio data; and providing, for output by the given mobile device, the transcription.
