7. A method of providing feedback for a speech recognition system of a computing device, the method comprising: displaying a graphical feedback indicator with an appearance indicating that the speech recognition system is in a passive listening mode, the graphical feedback indicator having a variable appearance depending upon a state of the speech recognition system; receiving a triggering input; in response to the triggering input, modifying the appearance of the graphical feedback indicator to have an appearance that indicates the speech recognition system is in an active listening mode; while in the active listening mode, receiving a speech input; when the speech input is heard, modifying the appearance of the graphical feedback indicator to indicate that the speech input is heard; when the speech input is understood, modifying the appearance of the graphical feedback indicator to indicate that the speech input is understood, determining a location of a user providing the speech input, and modifying the appearance of the graphical feedback indicator to indicate the location of the user by adjusting a location of a volume indicator in a direction corresponding to the location of the user, the volume indicator comprising a ring-shaped portion of the indicator having a bar that represents a volume, wherein adjusting a location indicator comprises moving the bar to a side corresponding to the location of the user providing the speech input; and when the speech input is not understood, modifying the appearance of the graphical feedback indicator to indicate that the speech is not understood.
