Signal processing for computer-assisted instruction of sight singing [PDF]
The Journal of the Acoustical Society of America, 1995 SST (Sight Singing Tutor) is a computer-assisted instructional program to teach the skill of singing melodies at sight. The program displays a melody on the screen, accepts acoustic input from a user, then evaluates the user’s attempt to sing the melody. SST’s primary signal processing tasks are frequency identification, note segmentation, and matching
