New sing software has proven to fix most pitchy voice problems with improvements beginning within just a few minutes. Sing software can be divided into several categories. First, there are basic effects that can be applied to the voice just as to any instrument. Next, the voice can be modified after performance in the post recording and production cycle. Even earlier, the voice can be adjusted during performance to improve a variety of oddities, including pitchy voice. However, the latest wave of sing software is a line of products that actually train a singer to sing on pitch.
It may seem hard to believe that software could fix a pitchy voice, but the experimental data shows that most people can benefit. At the core of this software is a real time graphic visual display of the singers pitch. This bio feedback empowers the singer to correct their pitch immediately. Furthermore, the improvement in pitch lasts after the software is turned off. Though, to be clear, the improvements begin to fade over time and regular use of the software is encouraged. One theory about why this software is so effective is that commonly people listen to their voice from the audio signal that travels through the head, which is the loudest signal. But, there is additional audio information that reaches the ears from the outside, by reflection from the environment. The theory is that the visual feedback helps the singer focus attention on the outer or incoming audio signal.
