Exam 2 Part 4 Flashcards
What part of the brain does speechreading activate?
Auditory cortex
Using auditory and visual cues to recognize speech; for people with hearing loss, they rely more on visual cues
Speech reading
Absence of _____ signal decreases speech recognition
Visual
What are the 3 main predictors of speech reading success (3)?
Cognitive skills, age, type of hearing loss
What are other types of possible predictors of speech reading success?
Verbal inference, contextual cues, closure abilities, willingness to guess, mental agility, grammar/vocabulary, neurophysiologic measures
What are factors that influence the ability and difficulty of speechreading and their success (5)?
Visibility of sounds, rapidity of speech, coarticulation and stress effects, talker effects, visemes and homophones
____ latencies typically do better on speechreading
Shorter
What types of phonemes are more visible to those with hearing loss during speechreading?
Consonants with lip closure and tongue to front of mouth
What phonemes are not as visible to those with hearing loss during speechreading?
Vowels
__% of speech sounds in English are not visible during speechreading
60%
What are some factors that may influence the rapidity of speech (4)?
Emotion, social etiquette, fatigue, articulation style
What is the average amount of words do we produce during conversation?
150-250
What types of speech (fast or slow) is harder to understand?
Faster speech
Same phoneme may look different, influenced by vowel following consonant; same word looks different depending on speaker’s stress
Coarticulation
Groups of phonemes that look same on lips that are indistinguishable without voice
Visemes
