-analysis of speech begins with Phoneme (minimum unit of sound in language)
-one distinction we can make in sounds is voice-onset time ( delay of the initial sound of
a consonant and the onset of vibration of the vocal chords)
-perception of a phoneme is affected by the sound that follows it
-phonemes cobind to form Morphemes (smallest unit of meaning in language)
