Introduction: Training is an integral part of learning any skill. The vocal training helps singers 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.
Methods: Group 1 consisted of 30 trained male Carnatic singers with lower vocal training, and group 2, thirty 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 2-week interval between the tests. Cross-sectional study design was applied.
Results: The statistical analysis revealed significantly decreased frequency-related parameters (semitones) such as the mean fundamental frequency, lowest fundamental frequency, highest fundamental frequency at the low register and the highest fundamental frequency at the middle register in group 2 during "mkaram" task (p ≤ 0.05). Similarly, one of the spectral-related measures 1st harmonic-2nd harmonic (dB) during lyrical task and one of the noise-related measure harmonic-to-noise ratio (dB) at the middle register during "mkaram" task showed a significant decrease in group 2 compared to group 1 (p ≤ 0.05). Test-retest reliability revealed that most of the parameters had "acceptable to excellent" internal consistency (Cronbach's α >0.7 to 1).
Conclusion: Few frequency and noise measures during "mkaram" task and a spectral measure during lyrical task showed to be sensitive in distinguishing the impact of vocal training on the voices of male Carnatic singers. The higher vocal training was found to help the singers to perform more efficiently with enhanced vocal range particularly in the low register and to some extent in the middle register. Indeed, the study highlighted the positive effects of vocal training on male Carnatic singers.

This study develops an innovative method for analyzing and clustering tonal trends in Chinese Yue Opera to identify different vocal styles accurately. Linear interpolation is applied to process the time series data of vocal melodies, addressing inconsistent feature dimensions. The second-order difference method extracts tonal trend features.

Background: Echolocating bats face an intense arms race with insect prey that can detect bat calls and initiate evasive maneuvers. Their high closing speeds and short biosonar ranges leave bats with only a few 100 ms between detection and capture, suggesting a reactive sensory-motor operation that might preclude tracking of escaping prey. Here we test this hypothesis using greater mouse-eared bats (Myotis myotis) as a model species.

In otolaryngology, training often involves simulation in animal specimens, human cadavers, and artificial models to facilitate learning surgical procedures, reducing the time needed to acquire essential skills. Simulated training has become integral to medical education, particularly in microsurgical techniques, such as microlaryngeal surgery. These procedures, also known as phonomicrosurgery, are performed on the vocal folds using microscopic visualization and precision instruments with long shafts and millimetric tips.

The current study has revealed a unique sexual selection pattern in , a species renowned for its ultrasonic communication, which differs from the patterns observed in other anuran taxa. Typically, females listen to male vocalizations and exhibit phonotaxis towards preferred traits for mate selection. In contrast, female do not actively approach displaying males for mate selection; instead, they use courtship calls to attract potential mates and incite male competition for access to them.

This study aims to provide a comprehensive picture of auditory emotion perception in cochlear implant (CI) users by (1) investigating emotion categorization in both vocal (pseud-ospeech) and musical domains, and (2) how individual differences in residual acoustic hearing, sensitivity to voice cues (voice pitch, vocal tract length), and quality of life (QoL) might be associated with vocal emotion perception, and, going a step further, also with musical emotion perception. In 28 adult CI users, with or without self-reported acoustic hearing, we showed that sensitivity (d') scores for emotion categorization varied largely across the participants, in line with previous research. However, within participants, the d' scores for vocal and musical emotion categorization were significantly correlated, indicating similar processing of auditory emotional cues across the pseudo-speech and music domains and robustness of the tests.
