Changes of Voice Production in Artificial Acoustic Environments

The physical production of speech level dynamic range is directly affected by the physiological features speaker such as vocal tract size and lung capacity; however, regulation these systems perception communication environment auditory feedback. current study examined effects room acoustics in an artificial setting on voice terms sound pressure relationship with perceived comfort control. Three independent acoustic parameters were considered: gain (alteration sidetone or playback one’s own voice), reverberation time, background noise. An increase led to a decrease levels, thus increasing This effect was consistent different times considered. Mid-range (T30 ≈ 1.3 s) along control, time smaller than gain. presence noise amplified aforementioned for variables analyzed.
