Measuring the distortion of speech by a facemask
JASA Express Letters, 2022 Most prior research focuses on the reduced amplitude of speech caused by facemasks. This paper argues that the interaction between the acoustic properties of a facemask and the acoustic properties of the vocal tract contributes to speech distortion by changing the formants of the voice. Speech distortion of a number of masks was tested by measuring the

Henceforth, facemasks' "therapeutic" role against SARS-CoV-2 must be explored because personal "therapeutic" environments may get created ...
