 When looking at vowel quadrilaterals, what order will they be in from highest to lowest? | children, women, men |
| The gross differences in formant frequencies are related to the ... | different sizes in vocal tracts |
| What might be valuable cues that the brain uses to decode sounds? | timbre and pitch |
| The production of vowels can be influenced by the sounds that are adjacent to it. This is known as what? | coarticulation |
| What are the corner vowels? | a, i, u, ae |
| When a person is producing normal speech, it is common for the corner vowels (a,i,u,ae) to be what? | undershot or not quite achieved |
| When a vowel is undershot in normal speech, the position of the tongue is a little closer to the neutral vowel /ə/ (schwa) in the middle of the vocal tract. This is known as what? | vowel neutralization |
| In what type of motor speech disorder is it common for the vowels to be under-articulated too much, and the speech distorted? | dysarthrias |
| In research, what can be used to quantify how well a person is articulating? | vowel quadrilateral |
| If you look at a person's vowel space area within their vowel quadrilateral, and it has increased after some treatment, what is this indicative of? | larger articulator movements and increased intelligibility |
| What are vowel ellipses? | a reflection of how much variability there can be in the first and second formants, as you produce that vowel in different contexts |
| What is a reflection of how much variability there can be in the first and second formants, as you produce that vowel in different contexts? | vowel ellipses |
| Most languages have how many vowels? | 3-9 |
| T or F: Vowels on the outer edges of the quadrilateral are easier to distinguish, and those toward the middle of the quadrilateral are harder to distinguish. | T |
| What is meant by formant transitions? | a change in F1 and F2 as coarticulation occurs in C to V and V to C transitions |
| Are vowels steady states? | no, they are formant histories |
| What is a monopthong? | an ordinary vowel with a relative clear steady state |
| How is a dipthong defined? | by the change or movement of it's formant |
| What happens to formant frequencies during production of a dipthong? | they will change |
| What is an onglide? | the starting frequency before movement begins in a dipthong |
| What is an offglide? | the ending frequency after you finished making a dipthong |
| In between the onglide and offglide, what happens? | there is a transition where the formants are changing |
| It is the ____ __ __ _____ that really defines the dipthong that we perceive. | movement of the formants |
