Ch 4- Vowels
Monophthongs
"one sound". sounds that have one primary articulatory position in the vocal tract.
Diphthongs
"two sounds" Two vowels that comprise one phoneme sound.
Categorized in relation to the position of the body of tongue in mouth during production. Ex. height and advancement of tongue
How are vowels categorized?
high mid front tense (unrounded) vowel. Referred to as high mid vowel.
Lower Case e
high mid back tense rounded vowel.
Lower Case o
high back tense rounded vowel. Usually has the j phoneme before it in some words such as "few" "fju"
Lower Case- u
high front lax (unrounded) vowel. Can be part of the end of a word that has unstressed that ends in -y and words with -ing in them. Also becomes this when have /r/ after the i, or ɪ sound.
Small Capital I
tongue height, tongue advancement, lip rounding, and tense/lax.
What are the characteristics of Vowels?
I, ə, ʌ, ɛ, æ, ɚ, ʊ
What are the lax vowels?
i, u, a, æ
What are the point vowels of the quadrilateral?
i, e, u, o a, ɔ, ɝ
What are the tense vowels?
æ ɪ i e ɑ ə ʌ ɛ
What are the unrounded vowel symbols?
vowels and dipthongs. Will appear darker on spectograms.
What have more intensity? Vowels or consonants?
tongue is placed in appropriate position for production of first element, then tongue moves to second element in continuous gliding motion. Tongue rises in mouth when moving from onglide to offglide. Therefore the offglide is produced at higher position in oral cavity that onglide.
What occurs in articulation during diphthongs?
The tongue moves positions and jaw position also changes depending on the sound. As tongue changes position for production of vowels, size and shape of pharynx does too. Airstream passes through oral cavity with virtually no obstruction by tongue or other major articulators.
What occurs in phonation of vowels?
Resonance
deals with the vibratory properties of any vibrating body. Frequency of vibration.
ɑʊ
diphthong like cow.
eɪ
diphthong of e vowel and is high mid front tense (unrounded) vowel. Usually occurs in stressed syllables and at the end of words regardless of stress when vowel is lengthened.
ɔɪ
diphthong sound as in boy or toy
ɑɪ
diphthong. like ice
Time
duration of any particular sound
oʊ
high mid back tense rounded vowel. occurs in stressed syllables and at end of words regardless of stress.
Lower Case i Vowel
high- front tense (unrounded) vowel
Tongue Advancement
how far forward or backward in the mouth the tongue is when making a certain vowel sound.
Tongue Height
how high or low in mouth tongue is when producing a certain vowel
Script a
low back tense unrounded. Also forms ar the r-colored vowel. can be confused with ɔ and vise versa.
Open o ɔ
low mid back tense rounded vowel.
Turned V "Wedge" ʌ
low mid, back central, lax unrounded vowel. Used in stressed syllables.
Right hook Schwa "Schwar" ɚ
mid central lax rounded vowel. occurs only in unstressed syllables
Right hook reversed Epsilon ɝ
mid central rounded tense vowel. occurs only in stressed syllables
Frequency
number of cycles a vibrating body completes in one second. It is perceived in terms of pitch. Are related and as it changes so does pitch.
Vowel Quadrilateral
oral cavity shape figure that gives an approximation of tongue position for the production of vowels.
Vowels
phonemes that are produced without any appreciable constriction or blockage of air flow in vocal tract.
Intensity
refers to amplitude of energy associatd with particular sound. The greater the energy, the greater this is. It is perceived in terms of loudness. As it increases of a sound, so does its loudness.
Formants
resonant frequencies of vocal tract. Each vowel has specific frequency due to the tongue positioning in the vocal tract.
Timbre
synonym often used for sound quality
Onglide
the first element in a diphthong when pronouncing the first phoneme
Low tongue
the jaw is dropped so the tongue is below the position that it would occupy in a non-speech activity (breathing)
Quality
the perceptual character of a sound based on its acoustic resonance patterns
offglide
the second element in a diphthong when pronouncing second sound.
Center Tongue
the tongue is close to the "rest" position during articulation. This is half way between the hard palate and the velum.
Front tongue
the tongue is forward in the mouth during articulation. But don't be fooled by this term. Front does not mean all the way to bilabial. Front for vowels means in the palatal area.
Back tongue
the tongue is pulled back during articulation to the velar area
high tongue
tongue is raised towards hard palate
mid tongue
tongues is slightly raised towards the hard palate
rhotic dipthongs or r-colored vowels
vowel has r quality or r coloring associated with it. ex. hear and ear.
Point vowels
vowels that represent an extreme corner of vowel quadrilateral.
Tense Vowels
vowels which are longer in duration and require more muscular effort.
Lax Vowels
vowels which are shorter in duration and require less muscular effort.
two vowels, /I/ (front vowel) or /ʊ/ (back vowel)
what do offglides consist of?
tongue
what is the primary articulator of vowels?
nasalization
when a vowel takes on a nasal quality due to phonemic environment of a word. Usually occurs when preceding or following a nasal consonant. Ex. "Rim"
Rounded/ Unrounded Vowel sounds
whether a vowel has lip rounding when producing it or not. Ex. "moon" and "mean"
most vowels produced in back of mouth are rounded
Are vowels produced in back of the mouth, rounded or unrounded?
unrounded
Are vowels produced in front of mouth rounded or unrounded?
low front lax (unrounded) vowel. Referred to as "ash". used before ŋ in words like "rank".
Ash æ
low mid front lax (unrounded) vowel. called epsilon. Usually occur before /r/.
Epsilon ɛ
mid central lax unrounded vowel. Commonly known as schwa.
Schwa ə
Spectrum
The frequency array, or energy pattern, associated with particular phoneme. Vowel have low frequency spectra or low spectral pitch.
high (lower than u) back rounded lax.
Upsilon ʊ
Can be in beginning and in middle of word but never at the end! ex. "had" "aloud"
What syllabic position can lax vowels be?
Can be in middle and at the end of syllable creating an open syllable. ex. "Hi" "feet"
What syllabic position can tense vowels be?
ʊ u o ɔ ɚ ɝ
What vowels are rounded?
i, e, eɪ, ɪ, ɛ, æ
Which are front vowels?
Spectogram
a graphic representation of the three major parameters that describe the acoustic characteristics of any sound, including speech sounds. Parameter include time, frequency, intensity
