The Introduction Types of Vocal Sound in Choir in Realtime Using Hankel Transformation and Macdonald Function

A group sang in the choir consists of several parts, among others soprano voice, alto, tenor and bass. Prior to the formation of choral group first performed the determination of the sound of each singer by coach or expert vocal choir. Voice recognition process carried out with samples of recorded voice input and voice samples realtime on the program. Sounds are included in the sample will produce energy weight values based on calculations using the Hankel transform and Function Macdonald. The results showed that the accuracy of the system depends on the accuracy of sound techniques trained and tested, and obtained an average percentage of successful recognition of sounds in record reached 66.87%, while the average percentage of the successful introduction of the type of voice in real time reaches 72%.
