The number of Japanese consonants are more than the vowels, overwhelmingly. The Japanese consonants are de¯on;ned by ones articulated manner and articulated place, and a phonetic, change of them are quite complex. We remark a transient from stationary signal (like vowel) to nonstationary signal (consonant) which an amplitude of its time domain waveform has not uniform, and try to visualize a behavior of dynamics of some Japanese consonants in phase-space. A Recurrence Plot (RP) imaging analysis is surpassing method where we confront with non-stationary (or like) signals. In this report, we try to analyze particular signals in the between C-V (Consonant-Vowel) phonemes through using the RP analysis. As a result, we can show a quantitative measure from phase-space geometry of some Japanese consonant.
