IV. Explain the following terms.
1．Assimilation(南开大学2010研；武汉大学2008研；上海交大2005研)
【答案】It is a process by which one sound takes on some or all the characteristics of a neighboring sound. It is often used synonymously with coarticulation. Nasalization, dentalization and, velarization are all instances of assimilation. There are two possibilities of assimilation: if a following sound is influencing a preceding sound, it is regressive assimilation; the converse process, in which a preceding sound is influencing a following sound, is known as progressive assimilation. For example, in “mink”, “n”, which is originally pronounced as /n/, will be velarized by the following “k”/k/, and therefore the word will be pronounced as [mɪŋk].
2．Distinctive features of speech sounds (中山大学2008研；北师大2003研；北交大2005研，浙江大学2007研)
【答案】The distinctive feature is a property which distinguishes one phoneme from another. For example, “voicing” is a distinctive feature, since it plays an important role in distinguishing obstruents in English.
3．Syllable(四川大学2006研)
【答案】Syllable: It refers to a unit of spoken language that is bigger than a speech sound. It consists of one or more vowel sounds alone or of a syllabic consonant alone or of either with one or more consonant sounds preceding or following.
4．Cardinal vowel (四川大学2006研；大连外国语学院2008研)
【答案】Cardinal vowel: The cardinal vowels are a set vowel qualities arbitrarily defined, fixed and unchanging, intended to provide a frame of reference for the description of the actual vowels of existing languages.
5．Voiceless (西安交大2008研)
【答案】When the vocal folds are apart, the air can pass through easily and the sound produced is said to be voiceless. For example, consonants (p, s, t) are produced this way, so they are voiceless consonants. “Voiceless” is defined in contrast with “voiced”. Consonants (b, z, d) are voiced consonants.
6．Minimal pairs (武汉大学2005研；浙江大学2004研；四川大学2007研；上海交大2006研；北航2008研；北二外2006研)
【答案】The two words which are identical in every way except for one sound segment that occurs in the same place in the string. For example, the English words bear and pear constitute a minimal pair as they differ in meaning and in their initial phonemes /b/ and /p/.
7．Coarticulation (武汉大学2008研；四川大学2006研；南开大学2007研)
【答案】Coarticulation refers to the phenomenon of sounds continually show the influence of their neighbors. For example, as in lamb, when a is followed by m, the velum will begin to lower itself during the articulation of a so that it is ready for the following nasal. When such simultaneous or overlapping articulations are involved, we call the process coarticulation. If the sound becomes more like the following sound, it is known as anticipatory coarticulation. If the sound displays the influence of the preceding sound, it is preservative coarticulation.
8．Broad and narrow transcription (中山大学2006研)
【答案】Broad and narrow transcription: In broad transcription, one letter symbol is used for one sound. In narrow transcription, there are diacritics added to the one letter symbols to show the finer differences between sounds.
9．Complementary distribution (武汉大学2008研；南开大学2007研)
【答案】When two sounds never occur in the same environment, they are in complementary distribution. For example, the aspirated English stops never occur after (s), and the unaspirated ones never occur initially. Allophones of the same phoneme are usually in complementary distribution. The allophones of /p/, for instance, are also in complementary distribution. The unaspirated(p=) occurs after /s/, while the aspirated(ph)occurs in all other environments except after /s/.
10．acoustic phonetics (南开大学2011研)
【答案】Acoustic phonetics: It is one of the three branches of phonetics, it is the study of the physical properties of speech sounds.
11．SPEAKING (中山大学2011年研)
【答案】SPEAKING is a mnemonic way of summarizing certain components of speech which make possible the description and analysis of communicative behavior: S= Situation, P= Participants, E= Ends, A= Act sequence, K= Key, I= Instrumentalities, N= Norms, and G= Genres.
12．sonority scale
【答案】In English, consonant clusters in onset and coda positions disallow many consonant combinations, which is explained by the work of sonority scale. The degree of sonority of different classes of sound affects their possible positions in the syllable.
13．OCP
【答案】Tone sandhi leads to a general rule that also covers epenthesis in segmental phonology: Obligatory Contour Principle (OCP), which is the opposite of assimilation and applies to many cases involving phonological change due to adjacent occurrences of identical sound segments or suprasegmentals like tone and stress patterns.
V. Short answer questions
1．For the following words, state the conditions under which the different forms of the past tense appear. What determines whether /t/, /d/, or /id/ is used? What distinctive features define conditioning environment? (南开大学2004研)
【答案】/t/ appears after these sounds: /ʃ,p,k,s,tʃ/, /id/, is found after /t,d/, and /d/ occurs after /g,l,b,v,ð,n,aʊ,m,ŋ,eɪ/. The general factor to determine whether /t/, /d/, or /id/ is used is the distinctive feature of voicing. Therefore, /t/ occurs after a voiceless sound, except /t/; /d/ occurs after a voiced sound, except /d/; and /id/ occurs after either the consonant /t/ or /d/.
2．How are the vowels described usually? (北二外 2009研)
【答案】
Usually, the description of the vowels needs to fulfill four basic requirements:
(1) The height of tongue raising (high, mid, low);
(2) The position of the highest part of the tongue (front, central, back);
(3) The length or tenseness of the vowel (tense vs. lax or long vs. short), and
(4) lip-rounding (rounded vs. unrounded).
3．Why do we say language is primarily vocal? (厦门大学 2009研)
【答案】Language is system of arbitrary vocal symbols used for human communication. Language is primarily vocal, because sound or speech is the primary medium for all human languages, developed or “new”. Writing systems came much later than the spoken forms. The fact that small children learn and can only learn to speak (and listen) before they write (and read) also indicates that language is primarily vocal, rather than written. The term “human” in the definition is meant to specify that language is human specific.
4．What are the criteria used in phonetic description of vowels? (厦门大学2010研)
【答案】
As the vowels can not be described in the same way as the consonants, a system of cardinal vowels has been suggested to get out of this problem. The cardinal vowels are a set of vowel qualities arbitrarily defined, fixed and unchanging, intended to provide a frame of reference for the description of the actual vowels of existing languages. The cardinal vowels are abstract concept. The cardinal vowel diagram is a set of hypothetical positions for vowels used as reference points.
The description of English vowels needs to fulfill four basic requirements: (1) the height of tongue raising(high, middle or low); (2) the position of the highest part of the tongue (front, central , back); (3) the length or tenseness of the vowel(tense vs. lax or long vs. short); (4) lip-rounding(rounded vs. unrounded). For example,
[i:]: high, front, tense, unrounded vowel.
[u]: high, back, lax, rounded vowel.
5．In English, the phoneme /p/ is pronounced differently in pat, spat, and tap, can you form a rule that can generalize this linguistic phenomenon? (南开大学2010研)
【答案】
In English, there is a rule that /p/ is unaspirated after /s/ but aspirated in other places. So /p/ in pat, tap is aspirated but unaspirated in spat since it is after /s/. To bring out the phonetic difference, an aspirated sound is transcribed with a raised “h” after the symbol of the sound. So a phonetic transcription for peak is [phi:k] and that for speak is [spi:k]. So [p, ph] are two different phones and are variants of the phoneme /p/. Such variants of a phoneme are called allophones of the same phoneme. The allophones are said to be in complementary distribution because they never occur in the same context: [p] occurs after [s] while [ph] occurs in other places. We can present this rule as:
/p/: [p] / [s]____
[ph] elsewhere
(note: ____ is the position in which /p/ appears.)
In addition, sometimes a phoneme may also have free variants. The final consonant of tap may not be released by some speakers so there is no audible sound at the end of this word. Such phenomenon is called free variation.
6．What are the differences between voiced sounds and voiceless sounds in terms of articulation? (南开大学2004研)
【答案】When the vocal cords are spread apart, the air from the lungs passes between them unimpeded. Sounds produced in this way are described as voiceless, consonants [p, s, t] are produced in this way; but when the vocal cords are drawn together, the air from the lungs repeatedly pushes them apart as it passes through, creating a vibration effect. Sounds produced in this way are described as voiced [b, z, d] are voiced consonants.
7．Phoneme is the smallest meaningful unit of sound and morpheme is the smallest meaningful unit in grammar. (中山大学2011年研)
【答案】
A phoneme is a phonological unit; it is a unit that is of distinctive value. It is an abstract unit. It is not any particular sound, but rather it is represented or realized by a certain phone in a certain phonetic context. For example, the [P]sound in peak is called an aspirated [p], and the [p] sound in speak is an unaspirated [p]. Its distinctive features of a phoneme are capable of distinguishing meaning.
Morpheme is the smallest unit of language in terms of the relationship between expression and content, a unit that cannot be divided into further smaller units without destroying or drastically altering the meaning, whether it is lexical or grammatical. For example, the word “tourists” contains three morphemes. There is one minimal unit of meaning, tour, another minimal unit of meaning -ist (meaning “person who does something”), and a minimal unit of grammatical function -s (indicating plural).
Therefore, phoneme is the smallest meaningful unit of sound and morpheme is the smallest meaningful unit grammar.
(此题考查音素与词素的概念。)
8．In the African language Manika, the affix, the meaning of which is similar to that of the suffix-ing in English, has two phonetic forms, as shown in the data given below. You are required to
(1) give the two phonetic forms of the affix;
【答案】The two phonetic forms are: [ni] and [li].
(2) give the underlying form of the affix;
【答案】The underlying form is [ni].
(3) write a formal phonological rule to derive the underlying form of the affix to its phonetic forms, using the words [dumuni] “eating” and [sungoli] “sleeping” to illustrate the process of derivation (南开大学2011年研)
【答案】
[ni] → [ni] / [- vowel] ______
[ni] → [li] / [+ vowel, -u] ______
In the word sungo, the last sound [o] is vowel so -ing form of the word is sungoli. While the last sound of the word dumu is [u], which is quite an exception, the -ing form of the word is dumuni.
9．What are suprasegmental features? How do the major suprasegmental features of English function in conveying meaning?
【答案】
A suprasegmental feature refers to the phonemic features that occur above the level of sound segment. The major suprasegmental features in English include word stress, sentence stress, tone, and intonation. The location of stress in English distinguishes meaning.
For example, a shift of stress may change the part of speech of a word from a noun to a verb although its spelling remains unchanged. Tones are pitch variations, which are caused by the differing rates of vibration of the vocal cords. Pitch variations can distinguish meaning just like phonemes. When pitch, stress and sound length are tied to the sentence rather than the word in isolation, they are collectively known as intonation. Intonation plays an important role in the conveyance of meaning in almost every language, especially in a language like English.
10．What is free variation?
【答案】
Free variation is a linguistic term used both in phonology and sociolinguistics. In phonology, if two sounds occurring in the same environment do not contrast. For example, the substitution of one for the other does not generate a new word but merely a different pronunciation of the same word, the two sounds are said to be in “free variation”.
For instance, both either and direction are pronounced differently in British English and American English without changing their meaning, which are often caused by the regional differences.
11．What are vowels glide about? What differentiates pure or monophthong vowel from vowel glides?
【答案】When pure or monophthongs are pronounced, the quality remains constant throughout the articulation. In contrast, those where there is an audible change of quality are called vowel glides. Vowel glides are produced by moving from one vowel position to another through intervening positions. If a single movement of the tongue is involved, the glides are called diphthongs. A double movement produces triphthongs.
12．What is assimilation? Is it similar to coarticulation? What does it include?
【答案】Assimilation is a process by which one sound takes on some or all the characteristics of a neighboring sound. It is often used synonymously with coarticulation. Nasalization, dentalization and velarization are all instances of assimilation. There are two possibilities of assimilation: if a following sound is influencing a preceding sound, it is regressive assimilation; the converse process, in which a preceding sound is influencing a following sound, is known as progressive assimilation.
13．Please explain why *lkaps, *hlpe are not allowed in English.
【答案】In English, consonant clusters in onset and coda positions disallow many consonant combinations, which can be explained by the work of sonority scale. The degree of sonority of different classes of sound affects their possible positions in the syllable. According to the sonotiry scale, the most sonorous sounds are vowels, the least sonorous ones are stops, and between them are approximates, nasals and fricatives from the more sonorous to less sonorous. In *lkaps and *hlpe, it is clear that the vowels are put behind the stops which do not follow the normal sequence of the sonority scale, thus they are not acceptable in English.
14．What is stress and what factors may influence stress?
【答案】Stress refers to the degree of force in producing a syllable. The stresses may change in different situations. First, some suffixes may change the position of the stress. For example, the stresses change in words like 'chaos, cha'otic, com'municate, communi'cation, and 'humid, hu'midity. But the suffix -ive does not make such a change, so we have com'municative, not communi'cative. Second, alternations of stress also occur between compounds and phrases as well. A 'blackboard is used in the classroom for teachers to write on whereas a black'board is any piece of board that is black in color, so different stresses can influence the meanings of the words.
VI. Essay questions
1．Is English a language that uses a phonetic alphabet system? Explain briefly why or why not with examples. (北外2004研)
【答案】
The Phonetic Alphabet is a system of letters and symbols that are used to represent the individual sounds of a language. English is a language that uses a phonetic alphabet system because it is a phonographic language by nature.
There are mainly three types of language concerning its writing system: ideographic language which uses symbols (ideograms) to represent whole words or concepts (ideas), with Chinese as an example; syllabic language which word or concepts are represented by syllable, with Japanese syllabic system as an example; phonographic language which uses special alphabetic or other typographical characters to express the sounds of an actual spoken utterance in writing, with many European languages as examples. English uses alphabetic script to represent certain single type sound. For example, the sound which is written sh in English can be expressed by symbols of (∫) ship; and the sound that is written in c can be expressed by the symbol of(k)cup.
2．What are the differences between voiced sounds and voiceless sounds in terms of articulation? (南开大学2004研)
【答案】When the vocal cords are spread apart, the air from the lungs passes between them unimpeded. Sounds produced in this way are described as voiceless, consonants(p, s, t)are produced in this way; but when the vocal cords are drawn together, the air from the lungs repeatedly pushes them apart as it passes through, creating a vibration effect. Sounds produced in this way are described as voiced(b, z, d)are voiced consonants.
3．What are phonemes, phones and allophones? Explain their relationship with examples from English or Chinese. (北外2005研)
【答案】
A phoneme is a minimally distinctive set of sounds in a language that can signal a difference in meaning. It is an abstract phonological unit represented or realized by a certain phone in a certain phonetic context.
A phone is an individual phonetic unit or segment that occurs in speech. The speech sounds we hear and produce during linguistic communication are all phones. Each of the set of phones which correspond to a single phoneme of a language is called an allophone.
Phonemes are placed between slant lines (//) and phones are placed between square brackets ([ ]). Allophones of the same phoneme generally occur in different contexts and never distinguish one word from another.
For example, when we pronounce the two words peak and speak, we are aware that the sound [p] is pronounced differently, in the word peak, the sound [p] is pronounced with a strong puff of air stream; but the same stop sound is pronounced slightly differently in the word speak, the puff of air is withheld a little. The [p] sound in peak is called an aspirated [ph] and the [p] sound in speak is an unaspirated [p=].
There is a slight difference in the way they are pronounced, but such a difference does not give rise to difference in meaning. So /p/is a phoneme in the English sound system, and it can be realized differently as aspirated or unaspirated in different contexts. The phoneme /p/ in English can be realized as aspirated [ph] and unaspirated [p=], which are allophones of the phoneme /p/.
4．What are suprasegmental features? (西安外国语学院2006研)
【答案】
Suprasegmental features refer to the phonological features above the sound segment level. They are the phonological properties of such units as the syllable, the word, and the sentence. The major suprasegmental features in English are syllable, stress, tone and intonation.
The syllable refers to the phonological unit that is composed of one or more phonemes. Every syllable has a nucleus, which is usually a vowel. The nucleus may be preceded by one or more consonants called the onset and followed by one or more consonants called the coda.
Stress refers to the degree of force used in producing a syllable. For words of more than one syllable, one is more stressed than the other. The more stressed syllable is the primary stress while the less stressed syllable is known as the secondary stress.
Tones are pitch variations, which are caused by the differing rates of vibration of the vocal cords. Different rates of vibration produce what is known as different frequencies, and in auditory terms as different pitches. Pitch variations may be distinctive like phoneme, that is, when they may contribute to distinguish between different words.
When pitch, stress and sound length are tied to the sentence rather than the word in isolation, they are collectively known as intonation. When we speak, we change the pitch of our voice to express ideas. The same sentence uttered with different intonation may express different attitude of the speaker. In English, there are four intonation patterns: the falling tone, the rising tone, the fall-rise tone, and the rise-fall tone.
