This paper describes an experimental verification of the lip-synchronization effect in the auditory compensation system for the elderly people. Because the aging effect to the human sensory mechanism, the functionality of the elderly people's sensation is declined. The auditory sensation is also declined. Many of the elderly people have difficulty with a listening in the radio or TV program. Recent digital media technology can compensate such declined auditory functionality. The compensation mechanism regulates a speech speed. However, in the television system, there is well known problem, that is called lip-synchronization problem. Our previous related work already evaluated the efficiency of the speech speed controlled compensation method for the broadcasting equipments, but we also confirmed unnatural feelings with the lip-synchronization skew. So we intend to verify the lip-synchronization effect in the speech speed controlled compensation method, by using a subjective assessment. In this assessment, we used psychological index for evaluating the unnatural feelings corresponding to lip-synchronization skew. As a result of this assessment, we can evaluate the unnatural feelings quantitatively, also discuss the relationship between the lip-synchronization skew and the subjective impression.
