In music, the ability of pitch-correcting software to adjust the sound of a voice or instrument to the desired pitch is crucial. Unlike older software that trained on pairs of corrected and original vocals, Diff-Pitcher analyzes the visual representation (spectrogram) of original vocals requiring correction. According to Hai, Diff-Pitcher is notable not only for its ability to create authentic and controlled voices but also for the method used to achieve it. They believe Dif-Pitcher has a wide range of potential applications, including aiding those undergoing voice rehabilitation, particularly those with vocal impediments.
