morphology
syntax
semantics
pragmatics
phonetics
the study of sound of human speech
components of phonetics
words can be treated as a sequence of unit sounds
speech production systems
consequences of phonetics
can't cut and paste sounds (co-articulation)
separation between words isn't always obvious
ambiguity at phonetic level
identification of words out of context
ambiguity at word level
"he saw the flies. he files the saw"
ambiguity at sentence level
visiting relatives can be a nuisance
problems in phoneme identification (4)
competing signals (cocktail party)
segmentation problems
degradation of the speech signal
variability of the speech signal
McGurk effect
influence of visual information on phoneme identification
Co-articulation advantages
-information about different segments is spread across time
-you know that a /u/ is coming because of the type of /s/ you heard
co-articulation
overlap between articulation of neighboring phonemes also causes variation
co-articulation disadvantage
there are no constant acoustic targets in speech
the same phoneme can be presented as different sounds in different contexts
conversely, the same sound can be heard as different sounds in different contexts
factors that make it hard for machines to recognize speech (4)
co-articulation
rapid speech
different vocal-tract sizes
different dialects
Sequential model of word recognition
words are recognized left to right with identification of one word leading to the identification of the onset of the next
Sequential model evidence
preceding context can facilitate effect on mispronunciation detection, but following context does not have a facilitation on the detection of mispronunciations
