About Dr Calvin Peter Baker

Dr Calvin Peter Baker is a voice scientist and singing-voice specialist (BAPAM equivalent Voice Rehabilitation Coach; NCVS equivalent Vocologist) based in Auckland, New Zealand. He completed a Bachelor of Music in classical voice performance and has first-class honours and master's degrees in the specialisation of studio pedagogy. Calvin conducted his interdisciplinary doctoral research (PhD, Speech Science) at the University of Auckland, working between the School of Psychology and the School of Music. His research explores the links between self-perceptual and instrumental voice analyses and seeks to determine which tools are effective for tracking subtle changes in the singing voice. This work has clinical implications for working with singers with voice complaints, particularly in preventative and rehabilitative care. Calvin collaborates with international industry leaders in voice research and has published works in leading scholarly journals.

Calvin is experienced in teaching a wide variety of repertoire across genres. He enjoys working with singers of all ages and backgrounds in secondary and tertiary contexts as well as his private studio. His voice-pedagogy research explores the connections (or misalignments) between traditional voice pedagogy practice and contemporary understandings of vocal function and acoustics. Currently, Calvin serves as a lecturer in Vocal Anatomy for Singers (MUS193b) and contributes as a guest lecturer for Musicians' Health (MUS744) and Voice and Fluency (SPEECHSCI746). He is a Professional Teaching Fellow in the School of Music and an Honorary Research Fellow in Speech Science (School of Psychology), UoA.
