Patent ID: 8023666

Claim:
A non-transitory computer-readable medium storing a program causing a computer to execute a process for assisting voice input under a noisy environment the process comprising: obtaining a measured noise level value by measuring a noise level; obtaining route information concerning a drive route of a vehicle equipped with the computer; calculating a predicted noise level value by predicting a noise level on the drive route based on the route information; and outputting an instruction about at least one of a voice level at which voice should be spoken and speak timing, based on at least one registered voice level reference value and the measured noise level value, wherein the outputting determines a threshold noise level value as a threshold value under which proper voice input is possible, based on the at least one registered voice level reference value, and if the measured noise level value exceeds the threshold noise level value, the outputting predicts and notifies the speak timing when proper voice input is possible, based on the predicted noise level value.
