Computer-Aided Learning System Employing a Pitch Tracking Line

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.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS [0001] This is a continuation-in-part of pending patent application Ser. No. 11 / 137,025, filed May 25, 2005, scheduled to issue on Sep. 18, 2007 as U.S. Pat. No. 7,271,329, which claims priority from provisional application 60 / 576,233, filed May 28, 2004, the disclosures of each of which are hereby incorporated by reference herein.BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] This invention relates to computer-aided learning systems for facilitating the annunciation of human voice. More particularly, this invention relates to computer-aided learning systems that facilitates vocalizations such as singing. [0004] 2. Description of the Background Art [0005] Presently, there exist many systems for teaching a person how to sing in tune and on beat. Commonly, the prior art systems focus more on the technology employed than the visual presentation to the singer. Accordingly, without an appropriate visual interface for the singer...

AI Technical Summary

Benefits of technology

[0026] For the purpose of summarizing this invention, this invention comprises a computer-aided learning system to facilitate a human to control the pitch of their voice such as in singing a song. The invention further facilitates a human to control the rhythm of their voice. Accordingly, the software of the invention teaches one to “sing in tune” and “in rhythm”.

[0031] The invention further comprises a custom vocal range feature that allows a user to set their personal vocal range. The user sings first up and then down. The distance between the high and low pitch tracking lines is then used to establish the top and bottom of the user's vocal range. Once the range is set, it is preferably depicted graphically in the Sing Window by colored horizontal (e.g., green) lines. Each song and exercise is automatically transposed into a key that makes the song easy for the user to sing.

[0033] The invention further includes a tempo change feature that allows slowing the tempo of more difficult songs (without changing the key) which will allow the user to more easily learn to sing the song. After he learns to sing it, the tempo can be returned to normal.

[0035] Finally, from “pitch-matching” to “a cappella”, the invention allows the user to begin learning a song with only the melody and metronome playing (he turns off the accompaniment). In this way the user may focus on matching the pitch of the melody and the proper rhythm only. Once the user can get a good score in this operating mode, the user can add the accompaniment. When that mode is mastered, the user can mute the melody and sing only with accompaniment and metronome. Upon mastering the accompaniment and metronome, the user can mute the accompaniment (and metronome if desired) and sing “a cappella” which means without the support of any audible musical reference points.

Problems solved by technology

However, this patent fails to disclose a meaningful visual representation of whether the singer is singing in tune.

However, ™“Sing”, ™“Karaoke Revolution” and ™“Audio Mirror” systems do not display a real time tracking line.

However, none of the prior art systems visually quantifies the accuracy of a singer singing in tune or out-of-tune in a manner that teaches the singer how much to raise or lower the tone of their voice as the song is being sung.
