Phonological representation

What is a lemma?
Assigned gender of a word
Processes required for speech production?
Semantic (conceptualisation)
Syntactic (formulation)
Phonological (articulation)
Semantic (conceptualisation)
Intention to create speech links desired concept to the particular spoken words to be expressed, intended messages are formulated
Syntactic (formulation)
Linguistic form required for expression of the desired message is created, including grammatical encoding, morphology-phonological encoding and phonetic encoding
Phonological (articulation)
Execution of the articulatory store by the lungs, glottis, larynx, tongue, lips, jaw and other parts of the vocal apparatus
Levelt et al’s Speech Production Model (1999)
Conceptual stratum - information about ideas of a particular concept and how they relate to each other, word selection occurs
Lemma-stratum - information about the syntactic function of individual words including tense and function, makes sure words are placed in the correct place in sentence to make sense
Form stratum - syllabic information which is sent to the motor cortex where vocal apparatus physically produces speech sounds
