  • Speech
    • Cutler & Clifton Model 1999
      • Recognition
        • Retrieval of Lexical information
        • Prosodic Cues and Parsing
          • Pitch, Stress, Intonation, Rhythm, Pauses
        • Utterance Interpretation
          • Syntactic Analysis
          • Thematic Processing
      • Integration
        • Integration into discourse model
      • Decode
        • Select Speech from background
        • Transform to abstract representation
      • Segmentation
        • Activation of lexical candidates
        • Competition
    • Segmentation Problem
      • Non Lexical
        • Speech sounds not heard together m&r
        • Stress of initial syllable
        • Coarticulation - word boundaries
      • Hierarchal
        • Lexical
        • Metrical Prosody
        • Sgemental
    • The Mcgurk Effect 1979
      • We all lip read as we listen
      • Ba/Ga/Da
    • Features of Speech Perception
      • Left Cerebral Hemisphere
        • Location for speech perception, but not other auditory perception
      • Categorical Perception
        • Ability to discriminate sounds belonging to different and the same categories (l and r in Japanese Speakers)
      • Phonemic Restoration Effect
        • Top down processing. the *eel was on the axel/ orange/ table/ shoe
    • Motor Theory
      • Mimic the articulatory movements
      • Shop/Chop experiment - due to speech musculature forcing us to pause for chop
    • Trace Model
      • Feature, phoneme and word nodes
      • Nodes influence is proportional to activation levels
      • Exhitation and inhibition spreads among nodes, and pattern of activation develops
      • Word recognition determindedby activation level
    • Cohort Theory
      • Lexical, syntactic and semantic knowledfe
      • Every phoneme = lots of possible word
      • Recognition and competition
      • Recognition Point
