Document Summary
Slips of the ear results from inattentiveness, or if auditory signal is ambiguous/noisy (ex- misheard song lyriccs. Identifying the phonemes present in the speech signal and attaching meaning to the sounds we hear; matching them to representations stored in memory. Listener needs to identify phonemes (smallest units of speech, speech sounds, that carry meaning; consonants/vowels) and attach correct meaning that he/she hear done by matching sound to representation in memory. When you make a sound, you"re making sound wave (like when rock is thrown in water) Sound creates sound waves, which consist of frequency and amplitude. -frequency + amplitude freq shows when sound peaks; higher frequency=higher pitched, lower freq=lower pitch. -amplitude=loudness (lower amp = lower sound, higher amp=higher sound) Each speech sound creates different sound wave differ because each sound is produced/articulated differently. Some harmonics resonate (be prominent/emphasized have more energy in them); these are called formants: (f1 lowest, f2 next, f3 highest)
