Formant converting apparatus modifying singing voice to emulate model voice

A karaoke apparatus for producing a karaoke music to accompany a singing voice while modifying the singing voice to emulate a model voice, comprising:

• a tone generating section that generates the karaoke music according to karaoke data;
• an input section that collects the singing voice created by a karaoke player along with the karaoke music;
• an analyzing section that sequentially analyzes the collected singing voice to extract therefrom actual formant data representing resonance characteristics of a karaoke player's own vocal organ which is physically activated to create the singing voice;
• a sequencer section that operates in synchronization with progression of the karaoke music for sequentially providing reference formant data which indicates a vocal quality of the model voice and which is arranged according to the karaoke data in matching with the progression of the singing voice;
• a comparing section that sequentially compares the actual formant data and the reference formant data with each other to detect a difference therebetween;
• a modifying section that modifies frequency characteristics of the collected singing voice according to the detected difference so as to emulate the vocal quality of the model voice;
• and
• a mixer section that mixes the modified singing voice to the generated karaoke music in real time basis.

A method for modifying a singing voice to emulate a model voice, comprising the steps of:

• collecting the singing voice created by a singer;
• sequentially analyzing 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;
• sequentially providing in synchronization with progression of the singing voice 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;
• sequentially comparing the actual formant data and the reference formant data with each other to detect a difference therebetween during the progression of the singing voice;
• and modifying frequency characteristics of the collected singing voice according to the detected difference so as to emulate the vocal quality of the model voice.
