Word Boundaries
Word Segmentation
What term refers to the challenge of distinguishing boundaries between words in spoken language?
Different speakers produce the same sound differently
Define interspeaker variability in phoneme pronunciation
Influence of information on speech perception
What does the McGurk effect demonstrate in speech perception?
Humans have a specialized phonetic module for speech processing
What is the core concept of the special mechanism approach in speech perception?
Context serve as a cue to resolve ambiguous sounds
How does context influence speech perception?
Phonemic Restoration
What phenomenon invloves our speech recognition system initially considering different hypothesis about dividing a phrase into words?
It occurs when pronouncing a phoneme and the mouth shape transitions from the previous prepares for the next, causing slight variations
How does coarticulation contribute to phoneme variability?
Superior Temporal Sulcus
Identify the location within the cerebral cortex associated with the McGurk effect
Special approach categorical for speech, not for non-speech; General approach - categorical for both
Contrast categorical perception in speech sounds according to the special mechanism approach and general mechanism approaches
Filling in the missing phoneme using contextual meaning
Define phonemic restoration and its role in speech perception
Less than 40% of the time
How often do clear-cut pauses mark word boundaries in actual acoustical stimuli?
Gender, age, regional dialect
Name a factor that influences variablity in the pitch and tone of speakers
Hearing "dad" while watching the lips say "gag" and hearing "bab"
Explain a scenario were auditory information and visual information conflict in the McGurk effect
Humans use the same neural humans mechanisms for speech and non-speech sounds
What does the general mechanism approach propose about speech perception?
Integration of visual cues with auditory cues enhances accuracy
How do visual cues aid speech perception, as illustrated in the McGurk effect?
