1. A vehicle comprising:
- at least one memory configured to store a plurality of grammar elements associated with audible commands for the vehicle;
at least one microphone;
at least one user input capture device, wherein the at least one user input capture device comprises a sensor that detects a proximity of an arm, a hand, or a finger of a user to a vehicle function control input element; and
one or more processors configured to;
identify, based upon information received from the sensor, a user input associated with the vehicle function control input element;
select, based at least in part upon an evaluation of the identified user input, a function associated with the vehicle function control input element, wherein the function is associated with a subset of the plurality of stored grammar elements;
receive audio input from the at least one microphone;
identify, based upon an evaluation of the received audio input, a grammar element associated with the selected function; and
output information associated with the identified grammar element.

Abstract
Speech recognition systems and/or techniques are provided in which grammar elements and/or speech inputs are targeted to selected functions. One or more input capture devices facilitate the collection of user input associated with a vehicle, and a vehicle function may be selected based upon received user input. A subset of available grammar elements that are associated with audible commands for the selected function may then be identified and utilized to evaluate received audio input. In this regard, speech recognition may be targeted to the selected function.

24. One or more non-transitory computer-readable media storing computer-executable instructions that, when executed by one or more processors, cause the one or more processors to perform operations comprising:
-
identifying a plurality of stored grammar elements associated with audible commands for a vehicle; identifying a user input associated with the vehicle function control input element, based at least upon information received from a sensor, wherein the information is indicative of a proximity of an arm, a hand, or a finger of a user to the vehicle function control input element; selecting, based at least in part upon an evaluation of the identified user input, a function associated with the vehicle function control input element, wherein the function is associated with a subset of the plurality of stored grammar elements; receiving audio input; identifying, based upon an evaluation of the received audio input, a grammar element associated with the selected function; and outputting information associated with the identified grammar element. - View Dependent Claims (25, 26, 27, 28, 29, 30)
