A method of routing communications from a mobile device to a target device. A non-whispered speech target device routing list and a whispered speech target device routing list are stored at a memory that is accessible by the mobile device. The mobile device identifies speech characteristics associated with a speech input and further determines whether the speech input corresponds to a whispered speech based on the speech characteristics. When it is determined that the speech input corresponds to a whispered speech, the mobile device routes communications corresponding to the speech input to each target device included in the whispered speech target device routing list. When it is determined that the speech input does not correspond to a whispered speech, the mobile device either routes or refrains from routing communications corresponding to the speech input to each target device included in the non-whispered speech target device routing list.
