Perception of Speech
-we extract words from a stream of speech
Recognition of Speech Soundsknow difference between phoneme and morpheme
-human vocalization is distinguished from other sounds
-auditory system recognizes the patterns of speech rather than the sounds themselves
-when analyzing detailed information of speech the left hemisphere plays a large role
-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)
Recognition of words in continous speech: the importance of learning and context
-a special electrical signal (N100 Wave) appears after people hear onset of a word
-we use context to interpret meaning
Understanding the Meaning of Speech
Syntax – grammar
Relationships between Semantics and Syntax
-sentences can be
Deep structure – sentence representation in terms of meaning
Surface Structure – grammatical features of a sentence
Knowledge of the world
-comprehension of speech requires knowledge about the world and particular situations
which we encounter
-this knowledge is organized into
SCRIPTS – characteristics that are typical of a situation

Document Summary

We extract words from a stream of speech. Recognition of speech sounds know difference between phoneme and morpheme. Auditory system recognizes the patterns of speech rather than the sounds themselves. When analyzing detailed information of speech the left hemisphere plays a large role. 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) Recognition of words in continous speech: the importance of learning and context. A special electrical signal (n100 wave) appears after people hear onset of a word. Deep structure sentence representation in terms of meaning. Surface structure grammatical features of a sentence.
