[L. pectoralis, chest, + loqui, to speak]
The distinct transmission of vocal sounds during auscultation of the chest with a stethoscope. The words seem to emanate from the spot that is auscultated. Pectoriloquy is heard over cavities that communicate with a bronchus and areas of consolidation near a large bronchus, over pneumothorax when the opening in the lung is patulous, and over some pleural effusions.
