“…In contrast, the current preventative recommendation mainly provided by voice clinicians is to use personal voice amplification systems (Bovo et al, 2013;Jónsdottir et al, 2001Jónsdottir et al, , 2002Jónsdottir et al, , 2003McCormick & Roy, 2002;Roy et al, 2003). However, it has been empirically demonstrated that personal voice amplification devices actually worsen voice-related outcomes, ostensibly due to the relationship between amplification devices and increased room noise (a risk factor for voice disorders) (Banks et al, 2022;Nudelman et al, 2023). In addition to voice amplification, other devices exist to help speakers, such as sound field amplification (SFA), which aims to help speakers' voices reach listeners.…”

Purpose: Altered auditory feedback research aims to identify methods to strengthen speakers' awareness of their own voicing behaviors, diminish their perception of vocal fatigue, and improve their voice production. This study aims to compare the effects of two bone conduction devices that provide altered auditory feedback. Method: Twenty participants (19–33 years old, age: M [ SD ] = 25.5 [3.85] years) participated in a vocal loading task using a standard Forbrain device that provides filtered auditory feedback via bone conduction and a modified Forbrain device that provides only sidetone amplification, and a control condition with no device was also included. They rated their vocal fatigue on a visual analog scale every 2 min during the vocal loading task. Additionally, pre- and postloading voice samples were analyzed for acoustic voice parameters. Results: Across all participants, the use of bone conduction–altered auditory feedback devices resulted in a lower vocal fatigue when compared to the condition with no feedback. During the pre- and postvoice samples, the sound pressure level decreased significantly during feedback conditions. During feedback conditions, spectral mean and standard deviation significantly decreased, and spectral skew significantly increased. Conclusion: The results promote bone conduction as a possible preventative tool that may reduce self-reported vocal fatigue and compensatory voice production for healthy individuals without voice disorders.
