Description

態様の一例では、発声される音声を検知する音声センサと、音高指定キーの操作状態に基づいて第１の音高を決定する第１の音高決定手段と、前記音声センサにより検知された音声に基づいて第２の音高を決定する第２の音高決定手段と、前記第１の音高の楽音を発生させる第１の楽音信号を生成するとともに、前記第２の音高の楽音を発生させる第２の楽音信号を生成する音源手段と、前記第１の楽音信号及び第２の楽音信号を合成して出力する出力手段と、を備える。 In one example embodiment, the first pitch determining means for determining a voice sensor, a first pitch on the basis of the operation state of the pitch designation key for detecting a voice to be uttered, is detected by the voice sensor A second pitch determining means for determining a second pitch based on the voice; a first musical tone signal for generating a musical tone of the first pitch; and a musical tone of the second pitch. It comprises a tone generator for generating a second tone signal for generating an output means for outputting the first tone signal and the second tone signal synthesized and, the.

ボイス閾値検出手段５０３は、第２エンベロープ抽出手段２０２が抽出したボイス・エンベロープが所定の閾値であるボイス閾値を超えたか否かを判定し、超えた場合に、第２発音指示手段５０４に対して発音指示を行うように通知する。 The voice threshold value detection unit 503 determines whether or not the voice envelope extracted by the second envelope extraction unit 202 exceeds a predetermined voice threshold value. Notify you to give pronunciation instructions.
