ABSTRACT:
In a voice modifying apparatus for modifying a singing voice to emulate a model voice, a microphone collects the singing voice created by a singer. An analyzer sequentially analyzes the collected singing voice to extract therefrom actual formant data representing resonance characteristics of a singer's own vocal organ which is physically activated to create the singing voice. A sequencer operates in synchronization with progression of the singing voice for sequentially providing reference formant data which indicates a vocal quality of the model voice and which is arranged to match with the progression of the singing voice. A comparator sequentially compares the actual formant data and the reference formant data with each other to detect a difference therebetween during the progression of the singing voice. An equalizer modifies frequency characteristics of the collected singing voice according to the detected difference so as to emulate the vocal quality of the model voice.
