Why Whispering Breaks Speech Recognition Physics

Whispering is far more than quiet talking: the vocal folds stop vibrating, pitch completely disappears, and vowel formant frequencies shift upward while vowel space compresses. This deep acoustic change turns speech into turbulent noise, stripping key periodicity cues that separate sounds like 's' and 'z'. Speech recognition models manage the shift surprisingly well despite lacking training data, but understanding the biomechanics reveals why whispered vowels survive while stop consonants suffer.
