UNA DISTINCIÓN
Características como la sonoridad, el lugar y la manera de articulación pertenecen a fonos = segméntales.
Características como el acento pertenecen a un grupo de fonos = suprasegméntales o prosódicas.
La prosodia es el conjunto de inflexiones melódicas que hace la voz durante la producción de la cadena fónica. tono, intensidad (volumen), cantidad (duración)

KINDS OF LINGUISTIC PROSODY
Lexical and phrasal prosody, see next 2 slides
Sentence type and prosodic contour Contrastive (or emphatic or focal) stress Determining whether two sentences are
identical based on any of these stress patterns

LEXICAL PROSODY (CAPS MARK STRESSED SYLLABLE)
Noun vs. verb in English (±15) CONvert vs. conVERT
Thai naa with a rising pitch tone means “thick” naa with a falling pitch tone means “face”
LHD (but not RHD) affects both of these rules

PHRASAL PROSODY
Compound noun rule noun phrase: hot DOG (a dog that is hot) adjective+noun: HOTdog (a
frankfurter) noun+noun: SHEEPdog (a breed of dogs)
Stress retraction After eating FOURteen CAKES, he threw up. After eating fourTEEN, CAKES did not tempt him.
LHD (but not RHD) affects both of these rules

CONTRASTIVE (OR EMPHATIC OR FOCAL) STRESS [CLAUSAL PROSODY]
Examples The horses were racing from the BARN. The HORSES were racing from the barn.
LHD (but not RHD) affects this

SENTENCE TYPE AND PROSODIC CONTOUR
Types declarative: fall in pitch at end
I eat chocolate. interrogative: rise for yes-no question (a); fall for
interrogative pronoun (b) Do you eat chocolate? What do you eat?
imperative: even pitch throughout; rise in intensity at end Eat chocolate!
RHD (but not LHD) reduces accuracy and variation in pitch

MORE RECENT RESEARCH: LATERALIZATION OF ACOUSTIC CUES OR PARAMETERS Cue or parameter models seek hemispheric
specialization in some component of the acoustic signal which either flags a semantic construct (a cue) or constitutes a broad physical measure (a parameter).
I know of five well-articulated positions that have been set forth as the defining cue or parameter of hemispheric specialization: the acoustic transitions that make up a given
phonological segment the duration of the transitions the frequency of the spectral information the frequency of information in general the size of temporal integration windows categorical vs. graded relations
Normal speech confounds these hopelessly, so it will be quite a challenge to tease out and evaluate the contribution of any single one.
