The vocal training helps singers to attain proficiency as they are the most demanding vocal group of all professional voice users. Hence, it is necessary to evaluate the influence of training on the singer's voice. The current study objective was to investigate the influence of vocal training on voice measures (Acoustic and Aerodynamic) between male Carnatic singers with lower (6 months - 5 years) and higher (6 - 10 years) training using novel task 'mkaram' along with lyrical task.</p><p><strong>Methods: </strong>Group 1 consisted of 30 trained male Carnatic singers with lower vocal training, and group 2, 30 trained male singers with higher training in the age of 18-45 years. The acoustic (frequency-related parameter, cepstral, spectral, perturbation and noise) and aerodynamic measures (Maximum Phonation Time and s/z ratio) of voice were obtained. The test-retest reliability was conducted on a sample of 10% of the population from each group, with a two-week interval between the tests. Cross-sectional study design was applied.</p><p><strong>Results: </strong>The statistical analysis revealed significantly decreased frequency-related parameter (ST) such as mean fundamental frequency, lowest fundamental frequency, highest fundamental frequency at low register, highest fundamental frequency at middle register in group 2 during 'mkaram' task (p ≤ 0.05). Similarly, one of the spectral-related measure 1st Harmonic - 2nd Harmonic (dB) during lyrical task and one of the noise-related measure Hormonic-to-Noise Ratio (dB) at middle register during 'mkaram' task showed significant decrease in the group 2 compared to group 1 (p ≤ 0.05).

However, the treatments for these two types of lesions differ significantly. Therefore, it is imperative to use a multidisciplinary approach to properly recognize suspicious lesions. This study aimed to determine the important acoustic characteristics specific to benign and malignant VFLs.</p><p><strong>Methods: </strong>The acoustic model of voice quality was utilized to measure various acoustic parameters in 157 participants, including individuals with normal, benign, and malignant conditions. The study comprised 62 female and 95 male participants (43 ± 10 years). Voice samples were collected at the Shanghai Eye, Ear, Nose, and Throat Hospital of Fudan University between May 2020 and July 2021. The acoustic variables of the participants were analyzed using Principal Component Analysis (PCA) to present important acoustic characteristics that are specific to normal vocal folds, benign VFLs, and malignant VFLs.

The presence of formant dispersion (FD) as a weighted factor in PCA was exclusively noted in individuals with Reinke's edema. The amplitude ratio between subharmonics and harmonics (SHR) and its coefficients of variation were evident exclusively in the polyps group.
