What does the auditory analysis system do?
Identify phonemes in sound wave (small units of sounds)
- Distincitive sounds that language uses
Describe the function of the Auditory input lexicon
Stores sound patterns of known words

- output string of phonemes
Describe the phoneme level
Leads to speech production
What is the nemonic associated with the speech comprehension and production pathway?
What is the progressive flow of the pathway and the systems associated with each step?
HAASSPS
1) Heard word
2) Auditory analysis
3) Auditory Input Lexicon
4) Semantic system
5) Speech Output Lexicon
6) Phoneme Level
7) Speech
What are the three pathways through which you can repeat a word
1) Auditory Input Lexicon -> Speech Output Lexicon (No processing through semantic system)
2) Auditory Analysis System -> Phoneme Level
3) Go through the longer route which includes the semantic system
