1. A method of aiding a visual search in a list of learnable speech commands by making less frequently-used commands more salient and more frequently-used commands less salient comprising:

presenting a display list of commands to a user;

monitoring whether the user has uttered one of said commands;

measuring an evidentiary value related to the utterance of said uttered one of said commands, wherein said measuring comprises determining an initial time that a previous utterance uttered by the user ended, determining a succeeding time that the utterance of said uttered one of said commands started, and computing a time elapsed between the initial and succeeding times, said evidentiary value being the time elapsed between the initial and succeeding times, said evidentiary value being the time elapsed between the end of a previous utterance and the start of the utterance of said uttered one of said commands;

comparing the measured evidentiary value to a programmed value;

if the measured evidentiary value is less than the programmed value, decreasing a salience of the command; and

if the measured evidentiary value is equal to or greater than the programmed value, maintaining the salience of the command unchanged or increasing the salience of the command.
