Effects of different levels of training on singing power ratio and singers formant in classical singers

This paper presents the two parameters such as Singing power ratio (SPR) and Singer's
formant (Fs) for objectively evaluating singing talent/quality among three levels of singers.
Thirty singers' (10 junior level, 10 senior level and 10 vidwath level) sung sample of
'Lambodara' song was analysed using LTAS of CSL 4500 software to extract SPR. The
sample was sung at three conditions including (1) singing without background music, (2)
singing with background music at listening comfortable level and (3) singing with
background music at more than listening comfortable level. SPR and presence or absence of
F was analysed among the singers at three conditions. No interaction between conditions S
and levels of singing was found for SPR. Fs was not observed at all the three conditions
among three levels of singers. There was a gradual increment in the SPR value with the
increase in the years of training. Thus, SPR would be an objective tool to measure the
singing voice quality in Carnatic singers.
