| Research Abstract |
Changes in the singing and speaking voices of children (six male and six female) over a three-year period were observed and recorded. The results of acoustic analysis indicate that, for girls, those whose third formant (shown at 24kHz) is 10kHz and above will become sopranos, while those whose is 9kHz and below will become altos. This can be very useful from the standpoint of determining the future voice type. The study also showed that teaching the use of portamento and mixed voice in addition to differentiating between modal and falsetto register when singing, is effective in vocal training in and around the period of voice change.
