In this upgraded version of Voice de Onchicchi, a simple movie found under "Game Explanation" will explain how to play the game. The pitch gauge has also been improved to be easier to see. This version also features Unchicchi! The Chinese and English language versions have been released simultaneously. First, select from "Voice or Piano," then when Onchicchi appears, select the pitch of the sound that is made. Next, choose from "Child or Adult," to choose the play style. Select Adult to match the pitch to long voice playback, or select Child to take on short voice playback within the time limit as many times as you like. Please watch the "Game Explanation" movie for how to play the game. If you have 4 or more sound mistakes on the results screen, you can't proceed to the next stage. If you fail to proceed twice in a row, Onchicchi will change into Unchicchi. Clear two consecutive stages and Unchicchi will turn back into Onchicchi. This app is useful for children's sound training and adult voice training.
