Voice-related Biomarkers in Singing: Suggested Clinical Measurements Standards of Voice Complaints, Listeners’ Evaluation, Acoustical Measurement and Airflow

The routine use of voice-related biomarkers of basic acoustic parameters, fundamental frequency (F0), Jitter, Shimmer and Harmonics to Noise Ratio (HNR), Voice Handicap Index (VHI), GRABAS test and Maximum Phonation Time (MPT) in singing pedagogy is suggested. These measures make it possible to evaluate voice pedagogy methods in a way that opens for a valid discussion of scientific evidence in future Randomized Controlled Studies (RCTs). In the modern era, voice educators face a new set of technical computer-related challenges and there is a need to safeguard vocal health in diverse performances. The abundant literature of singing pedagogy should be revised and seen from these approaches. The history of singing pedagogy was therefore studied. This article traces the development of singing pedagogy in practice in cooperation with medical doctors. The evaluation was that routinely measuring the voice with voice-related biomarkers, also with the help of artificial intelligence, especially during the training period and also in periods of voice hazards, will not only add substantially to the dialogue between laryngologists/phoniatricians and singing pedagogy, but also be a great help.
