Chapter 2 Flashcards
Explain how vowels are produced (focus on the air obstruction)
Vowels are those sounds which are produced without any obstruction to the flow of air
in the vocal tract. They are speech sounds produced by a relatively free passage of breath through oral cavity, usually forming the most prominent and central sound of syllable.
Explain the terms pure and gliding vowels
Vowels can be divided into pure vowels (monophthongs) and gliding vowels (diphthongs and triphthongs). Pure vowels are speech sounds in which the tongue remains in a relatively fixed position during the entire duration of the vowel. Examples of pure vowels: /ɪ/, /ʊ/ ,/æ/,/ɜ:/…
Gliding vowels are diphthongs and triphthongs. Diphthongs are sounds which consist of a movement or glide from one sound to another within the same syllable. Examples: /aɪ/, /aʊ/, /ɔɪ/…
Triphthongs are glides from one vowel to another and then to a third, all produced fluently, without interruption. Examples: /aɪə/, /aʊə/
Define vowels from the phonetic and the phonological point of view.
Phonetically, vowels can be defined as voiced speech sounds produced by the relatively free breath, without any closure or narrowing in the vocal tract that would cause audible friction. From a phonological point of view, vowels can be characterized as those units which form the centre/ nucleus of syllables.
How do we describe vowels according to the length of vocal fold vibration?
Depending on how long the vocal folds vibrate during the production of vowels, we distinguish between (relatively) short and (relatively) long vowels. The absolute length of English vowels depends on the nature of the sounds that follow them.
How do we describe vowels according to the position of the soft palate
When the soft palate is raised (closing the entrance to the nasal cavity) the vowels produced are purely oral. When the soft palate is lowered, the vowels are nasalized.
How do we describe vowels according to the shape of the lips?
The shape of the lips or lip-rounding is another important variable of vowel quality. We distinguish three stages of lip-rounding. Lips can be rounded, as for /u:/, spread as /i:/, or neutral as for ə
How do we describe vowels according to the horizontal position of the highest point
of the tongue?
The tongue or more specifically its raised part can assume many different positions it the oral cavity. This mobility is usually horizontal that is the tongue can move from back to front and vice versa. According to this horizontal movement we distinguish three distinct tongue positions_ front, central and back vowels made it these positions can be respectively described as front, central and back.
How do we describe vowels according to the vertical position of the highest point of
the tongue?
The mandible, or lower jaw can assume different degrees of openness. These degrees play an important role in the production of vowels. Based on the degree of openness and the consequent vertical position of the tongue we distinguish 4 different types of vowels: close e.g. /i:/, close- mid (or half-close) e.g. /ɔ:/, open- mid (or half- open) /e/ and open /ɑ:/
How do we describe vowels according to the muscular tension of the tongue?
According to the muscular tension of the tongue English vowels can be divided into tense and lax. Tense vowels are those which are supposed to require greater muscular tension on the part of tongue, lax vowels are those in which the tongue is supposed to be held loosely. The terms tense and lax usually apply only to close vowels, i,e, /I/- /i:/.
Explain the cardinal vowel system.
Cardinal vowel system was devised by Daniel Jones. It allows to accurately define any vowel od any language. The vowels that form this system are called cardinal vowels. These are given as a standard reference system. They represent the range of vowels that the human vocal apparatus can make and this system allows us to describe, classify and compare the vowels of any language. Cardinal vowels are enclosed in square brackets, because they indicate the real physical articulations- speech- sounds. Cardinal vowels ate located on a specially shaped vowel diagram (quadrilateral) and they can be divided into primary cardinal vowels and secondary cardinal vowels. Primary cardinal vowels are very similar to the vowels in many European languages.
Describe/explain the cardinal vowel diagram.
Cardinal vowels no 1 has symbol [i] and it is produced by the front of the tongue raised as close as possible to the palate without any friction noise. It is the most front and close vowel that is possible to make Cardinal vowel no. 5 has the sybol [ɑ] and it is produced by the whole of the tongue as low as possible in the mouth, with a very slight raising at the extreme back. I tis the most open and back vowel that it is possible to make Cardinal vowel no. 8 has the symbol [u] and it is articulated by the back of the tongue raised as close as possible to the velum. It is a fully close and back vowel. Cardinal vowel no. 4 has the symbol [a] and it is a fully open front vowel. These four cardinal vowels represent extreme points it the pronunciation of vowels. Secondary cardinal vowels can be made by alternating the primary cardinal vowels in terms of lip rounding. (examples on the page 52 in book)
Explain the phenomenon of clipping concerning sound length.
The length of English vowels decreases when they are followed by a voiceless consonant. This phenomenon is called clipping and the rule applies to both short, long monophthongs and diphthongs.
Give the rules of clipping of English vowels
When English vowels are followed by a voiceless consonant it is slightly shortened- clipped. When it is followed by voiced sound or a pause it retains its original length- it is unclipped. Clipping is most noticeable with monophthongs and diphthongs in stressed syllables.
Explain the notions of falling and rising diphthongs and give examples.
English distinctive diphthongs are equivalent in length to the English long (relatively pure) vowels they consist of 2 vowel sounds, one of which is usually longer and more prominent. When the first part of diphthong is longer and more prominent, the diphthong is said to be falling (descending). When the second part is longer and more prominent, the diphthong is said to be rising (ascending). All English distinctive diphthongs occurring in a stressed syllable ale falling e.g. late, fight, here. In unstressed syllables however, diphthongs ɪə, ʊə are rising and the rest of the diphthongs are falling e.g. period, familiar, ambiguous.
Name English monophthongs.
/iː/ , /ɪ/ , /e/, /æ/, /ɑː/, /ʌ/, /ɒ/,/ɔː/, /ʊ/, /uː/, /ə/, /ɜː/
