← Language & CommunicationWhy does speech recognition software often struggle with consonant clusters in casual speech?
A)Vowels have greater articulatory variation
B)Coarticulation blurs consonant boundaries✓
C)Consonants carry less semantic weight
D)Users adapt to software limitations
💡 Explanation
Speech recognition struggles with consonant clusters due to coarticulation, a phonetic process where adjacent sounds blend, blurring acoustic boundaries. Because consonants have shorter durations and weaker amplitudes, their distinct features are smeared by neighboring sounds; therefore, recognizing them becomes harder, rather than other factors like semantic importance or user adaptation.
