title: [Preliminary experimental studies of whispered voice: subglottal pressure and postural aspects].
abstract: OBJECTIVE
  Whispered voice is investigated from the energetic point of view. Our hypothese is that whispered voice, and mainly the forced whispers are very similar to vocal effort, for non acoustic vocal parameters, and body movements.
  
  
  METHODS
  Two experiments are combined. The first experiment focused on the laryngeal aspects, mainly the subglottal pressure, and also the electroglottography. The second experiment analyzed the body movements associated with loud whispered voice.
  
  
  RESULTS
  No electroglottograhic wave was observed during the two experiments. The vocal intensity was always lower during whispered voice than during comfortable voice (p < 0.001). In experiment 1, subglottal pressure was significantly higher during forced whisper than during the other conditions (p < 0.001). In experiment 2, the amplitude of the trunk movements in the sagittal plane were greater during loud whisper than during comfortable voice (p < 0.001).
  
  
  CONCLUSIONS
  Whispered voice can be close to vocal loading, especially the loud whispered voice.
