Abstract
A computer-aided learning system to facilitate a human to control the pitch and rhythm of their voice. In a preferred embodiment for learning how to sing a song in tune, a display provides visual, real-time depiction of the singer's actual pitch compared to the “target” pitch they should be singing, thereby allowing the singer to interactively raise or lower the pitch of their voice.
Claims39
A method for learning, comprising the steps of:
- displaying a series of target pitch lines representative of target pitches on a display;
- displaying a target pitch box encompassed about each target pitch line;
- computing a pitch tracking line from an audio input;
- and
- displaying the pitch tracking line on the display;
- whereby the pitch tracking line visually appears within respective target pitch boxes when the pitch of the audio input is substantially in tune with the targeted pitch of the target pitch line therein by a predefined amount.
