Overview
"Stridency" refers to the perceptualintensity of the sound of a sibilant consonant, or obstacle fricatives or affricates, which refers to the critical role of the teeth in producing the sound as an obstacle to the airstream. Non-sibilant fricatives and affricates produce their characteristic sound directly with the tongue or lips etc. and the place of contact in the mouth, without secondary involvement of the teeth.
