15. A mobile computing device comprising: one or more computer processors; a pose identifier that is programmed to identify a first pose with which the mobile computing device is being held by a user and a second pose with which the mobile device is being held by the user, the first and second poses being identified from among a plurality of predetermined poses, and the first pose being distinct from the second pose; a microphone that is programmed to initiate a first audio recording process after identification of the first pose and a second audio recording process after identification of the second pose; a speech detector that is programmed i) to select a first set of one or more parameters from among a plurality of parameters based on the first pose, wherein the first set of one or more parameters define settings that are specific to the first pose to differentiate between, at least, speech and background noise when the mobile computing device is being held in the first pose, ii) to detect, using the first set of one or more parameters, that the user has started speaking during the first audio recording process, iii) to select a second set of one or more parameters from among the plurality of parameters based on the second pose, wherein the second set of one or more parameters define settings that are specific to the second pose to differentiate between, at least, speech and background noise when the mobile computing device is being held in the second pose, and iv) to detect, using the second set of one or more parameters, that the user has started speaking during the second audio recording process; and a speech endpointer that is programmed i) to determine, after the user has started speaking and using the first set of one or more parameters, whether the user has stopped speaking during the first audio recording process, ii) to stop the first audio recording process based on determining that the user has stopped speaking during the first audio recording process, iii) to determine, after the user has started speaking and using the second set of one or more parameters, whether the user has stopped speaking during the second audio recording process, and iv) to stop the second audio recording process based on determining that the user has stopped speaking during the second audio recording process.
15. A mobile computing device comprising: one or more computer processors; a pose identifier that is programmed to identify a first pose with which the mobile computing device is being held by a user and a second pose with which the mobile device is being held by the user, the first and second poses being identified from among a plurality of predetermined poses, and the first pose being distinct from the second pose; a microphone that is programmed to initiate a first audio recording process after identification of the first pose and a second audio recording process after identification of the second pose; a speech detector that is programmed i) to select a first set of one or more parameters from among a plurality of parameters based on the first pose, wherein the first set of one or more parameters define settings that are specific to the first pose to differentiate between, at least, speech and background noise when the mobile computing device is being held in the first pose, ii) to detect, using the first set of one or more parameters, that the user has started speaking during the first audio recording process, iii) to select a second set of one or more parameters from among the plurality of parameters based on the second pose, wherein the second set of one or more parameters define settings that are specific to the second pose to differentiate between, at least, speech and background noise when the mobile computing device is being held in the second pose, and iv) to detect, using the second set of one or more parameters, that the user has started speaking during the second audio recording process; and a speech endpointer that is programmed i) to determine, after the user has started speaking and using the first set of one or more parameters, whether the user has stopped speaking during the first audio recording process, ii) to stop the first audio recording process based on determining that the user has stopped speaking during the first audio recording process, iii) to determine, after the user has started speaking and using the second set of one or more parameters, whether the user has stopped speaking during the second audio recording process, and iv) to stop the second audio recording process based on determining that the user has stopped speaking during the second audio recording process. 18. The mobile computing device of claim 15 , wherein the first pose that is identified by the mobile computing device comprises a telephone pose that indicates that the mobile computing device is being held up to the user's ear.
