PROBLEM TO BE SOLVED: To help a driver quickly understand a diversified "voice guidance".SOLUTION: A drive support device, for use in generating a reproduced sound near to an ear of a driver by using left-right parametric speakers 2, 3, provides the driver's right ear directly with "voice guidance", of "voice information useful for driving", from only a right speaker R1. A speech center is in the left brain and therefore "voice guidance" reaches the speech center in priority without being impeded by other sounds, helping quick understanding of "voice guidance". Further provision of rhythmic "voice guidance" facilitates hearing. Further, inclusion of "subliminal voice information" helps quick understanding of "voice guidance" by virtue of a subliminal effect. Additionally to above, combination of "different-content voice guidance" with "different alarm sound" helps understanding of "content of voice guidance" by hearing the beginning of "alarm sound" by the driver being accustomed (learning), enabling instant discrimination of diversified "voice guidance". |
