We have been studying how to stimulate a fingertip in order to improve our tactile aid for deaf people. In previous study, we have proposed the usage of tactile sensation that was caused by vibratory or Braille-like convex stimulation. In this study, we have designed new stimulation method that stimuli of consonant or vowel part of speech were presented with vibratory or convex stimulation pattern. From the experimental result, the consonant identification rate became the highest when vibratory stimulation was used for consonant part and convex stimulation was used for vowel part. So, we considered that the consonant identification became easier when the quality of tactile sensation was utilized to tactile aid.
