Thank you very much for this comment. The autonomic influence on the motor
systems of swallowing might be relevant to the adduction of the false vocal
folds or aryepiglottic folds, which prevent food from entering the lung.
This may explain that one feels supraglottal structures 'pressed' while in
anger or danger. From this standpoint, rough voices is a by-product of the
'fight or flight' reaction about swallowing.
Is there any reference about that emotional-stress-induced adduction of
FVFs or AFs could be related to autonomic influence on the motor systems of
It is my feeling that rough voices due to FVFs or AFs adduction should not
be regarded as a by-product of 'fight or flight' reactions. Such rough voice
qualities are paralinguistic cues in human acoustic communication. FVFs and
AFs may receive sub-cortical influence - just like that many muscles in
the face receive sub-cortical influence - to reveal one's emotional state.
Of course, facial expressions are not just side effects of emotions.
