1、Chapter Two Speech Sounds,As human beings we are capable of making all kinds of sounds, but only some of these sounds have become units in the language system. We can analyze speech sounds from various perspectives and

2、 the two major areas of study are phonetics and phonology.,Phonetics studies how speech sounds are produced, transmitted, and perceived.,,Articulatory Phonetics is the study of the production of speech sounds.Acoustic P

3、honetics is the study of the physical properties of speech sounds.Perceptual or Auditory Phonetics is concerned with the perception of speech sounds.,,Phonology is the study of the sound patterns and sound systems of la

4、nguages. It aims to ‘discover the principles that govern the way sounds are organized in languages, and to explain the variations that occur’.,In phonology we normally begin by analyzing an individual language, say Engl

5、ish, in order to determine its phonological structure, i.e. which sound units are used and how they are put together. Then we compare the properties of sound systems in different languages in order to make hypotheses ab

6、out the rules that underlie the use of sounds in them, and ultimately we aim to discover the rules that underlie the sound patterns of all languages.,1. How speech sounds are made,1.1 Speech organs,,Position of the voca

7、l folds: voiceless,Position of the vocal folds: voicing (initial & the widest aperture),Position of the vocal folds: glottal stop,1.2 The IPA,In 1886, the Phonetic Teachers’ Association was inaugurated by a small gr

8、oup of language teachers in France who had found the practice of phonetics useful in their teaching and wished to popularize their methods. It was changed to its present title of the International Phonetic Association (

9、IPA) in 1897.,One of the first activities of the Association was to produce a journal in which the contents were printed entirely in phonetic transcription. The idea of establishing a phonetic alphabet was first propose

10、d by the Danish grammarian and phonetician Otto Jespersen (1860-1943) in 1886, and the first version of the International Phonetic Alphabet (the IPA chart) was published in August 1888.,Its main principles were that the

11、re should be a separate letter for each distinctive sound, and that the same symbol should be used for that sound in any language in which it appears. The alphabet was to consist of as many Roman alphabet letters as pos

12、sible, using new letters and diacritics only when absolutely necessary. These principles continue to be followed today.,,The InternationalPhoneticAlphabet(Revised to 2005),,2. Consonants and vowels,Consonants are pr

13、oduced ‘by a closure in the vocal tract, or by a narrowing which is so marked that air cannot escape without producing audible friction’. By contrast, a vowel is produced without such ‘stricture’ so that ‘a(chǎn)ir escapes in

14、 a relatively unimpeded way through the mouth or nose’.,,The distinction between vowels and consonants lies in the obstruction of airstream.As there is no obstruction of air in the production of vowels, the description

15、of the consonants and vowels cannot be done along the same lines.,2.1 Consonants,In the production of consonants at least two articulators are involved. For example, the initial sound in bad involves both lips and its f

16、inal segment involves the blade (or the tip) of the tongue and the alveolar ridge. The categories of consonant, therefore, are established on the basis of several factors.,,The manner of articulation refers to ways in w

17、hich articulation can be accomplished: the articulators may close off the oral tract for an instant or a relatively long period; they may narrow the space considerably; or they may simply modify the shape of the tract

18、 by approaching each other.,,Stop (or Plosive) __ Oral & NasalFricative(Median) ApproximantLateral (Approximant)TrillTap or FlapAffricate,,The place of articulation refers to the point where a consonant is made

19、. Practically consonants may be produced at any place between the lips and the vocal folds. Eleven places of articulation are distinguished on the IPA chart:,BilabialLabiodentalDentalAlveolarpostalveolarRetroflex,

20、PalatalVelarUvularPharyngealGlottal,,2.2 Vowels,Cardinal Vowels, as exhibited by the vowel diagram in the IPA chart, are a set of vowel qualities arbitrarily defined, fixed and unchanging, intended to provide a frame

21、 of reference for the description of the actual vowels of existing languages.,Jones: An Outline of English Phonetics (1918),Black: IPARed: English,The problematic area is that the initial sound in hot gives little turbu

22、lence, depending on how forcefully it is said, and in yet and wet the initial segments are obviously vowels. To get out of this problem, the usual solution is to say that these segments are neither vowels nor consonants

23、 but midway between the two categories. For this purpose, the term ‘semi-vowel’ is often used.,Languages also frequently make use of a distinction between vowels where the quality remains constant throughout the articula

24、tion and those where there is an audible change of quality. The former are known as pure or monophthong vowels and the latter, vowel glides.,,If a single movement of the tongue is involved, the glides are called diphtho

25、ngs. Diphthongal glides in English can be heard in such words as way [we?], tide [ta?d], how [ha?], toy [t??], and toe [t??].,,A double movement produces a triphthong, which is ‘a(chǎn) glide from one vowel to another and the

26、n to a third, all produced rapidly and without interruption’. They are really diphthongs followed by the schwa [?], found in English words like wire [wa??] and tower [ta??].,2.3 The sounds of English,Received Pronunciat

27、ion (RP)General American (GA)English consonants,,,The consonants of English can be described in the following manner:[p]  voiceless bilabial stop[b]  voiced bilabial stop[s]   voiceless alveolar

28、 fricative[z]   voiced alveolar fricative,English vowels,The description of English vowels needs to fulfill four basic requirements: the height of tongue raising (high, mid, low);the position of the highest

29、part of the tongue (front, central, back);the length or tenseness of the vowel (tense vs. lax or long vs. short), and lip-rounding (rounded vs. unrounded).,,We can now describe the English vowels in this way:[??]high

30、 front tense unrounded vowel[?]high back lax rounded vowel[?]mid central lax unrounded vowel[?]low back lax rounded vowel,3. From phonetics to phonology,Speech is a continuous process, so the vocal organs do not mo

31、ve from one sound segment to the next in a series of separate steps. Rather, sounds continually show the influence of their neighbors. For example, map, lamb.,3.1 Coarticulation,When such simultaneous or overlapping art

32、iculations are involved, we call the process coarticulation.,If the sound becomes more like the following sound, as in the case of lamb, it is known as anticipatory coarticulation. If the sound shows the influence of th

33、e preceding sound, it is perseverative coarticulation, as is the case of map.,,The fact that the vowel [?] in lamb has some quality of the following nasal is a phenomenon we call nasalization. To indicate that a vowel h

34、as been nasalized, we add a diacritic to the top of the symbol [?], as [??].,,[?] is aspirated in peak and unaspirated in speak. This aspirated voiceless bilabial stop is thus indicated by the diacritic ?, as [??], wher

35、eas the unaspirated counterpart is transcribed as [?].,When we use a simple set of symbols in our transcription, it is called a broad transcription. The use of more specific symbols to show more phonetic detail is refer

36、red to as a narrow transcription. Both are phonetic transcriptions so we put both forms in square brackets [ ].,3.2 Phonemes,Phonology is not specifically concerned with the physical properties of the speech production

37、system. Phoneticians are concerned with how sounds differ in the way they are pronounced while phonologists are interested in the patterning of such sounds and the rules that underlie such variations.,,Crystal: ‘Phonolo

38、gical analysis relies on the principle that certain sounds cause changes in the meaning of a word or phrase, whereas other sounds do not’. Minimal pairs testPhonemes,The word ‘phoneme’ simply refers to a ‘unit of expli

39、cit sound contrast’: the existence of a minimal pair automatically grants phonemic status to the sounds responsible for the contrasts.By selecting one type of sound instead of another we can distinguish one word from an

40、other.,,Languages differ in the selection of contrastive sounds. In English, the distinction between aspirated [??] and unaspirated [?] is not phonemic. In Chinese, however, the distinction between /?/ and /??/ is phon

41、emic.,,By convention, phonemic transcriptions are placed between slant lines (/ /) while phonetic transcriptions are placed between square brackets ([ ]). In phonetic terms, phonemic transcriptions represent the ‘broad’

42、 transcriptions.,3.3 Allophones,[?, ??] are two different phones and are variants of the phoneme /?/. Such variants of a phoneme are called allophones of the same phoneme. In this case the allophones are said to be in c

43、omplementary distribution because they never occur in the same context: [?] occurs after [?] while [??] occurs in other places.,,/?/ ? [?] / [?] _____ [??] elsewhereThis phenomenon of variation in t

44、he pronunciation of phonemes in different positions is called allophony or allophonic variation.,,Velarization: clear l and dark l/?/ ?[?] / _____ V[?] / V _____Think about tell and telling!,,Phonetic similari

45、ty: the allophones of a phoneme must bear some phonetic resemblance. Free variants and free variation,4. Phonological processes, phonological rules and distinctive features,4.1 Assimilation,Nasalization, dentalization

46、, and velarization are all instances of assimilation, a process by which one sound takes on some or all the characteristics of a neighboring sound. If a following sound is influencing a preceding sound, we call it regre

47、ssive assimilation; the converse process, in which a preceding sound is influencing a following sound, is known as progressive assimilation.,English Fricative Devoicing,/v/ ? [f] /z/ ? [s] etc.voiced fricative ? voi

51、 Elsewhere ConditionThe more specific rule applies first.,4.3 Distinctive features,The idea of Distinctive Features was first developed by Roman Jacobson (1896-1982) in the 1940s as a means of working out a set of phon

52、ological contrasts or oppositions to capture particular aspects of language sounds. Since then several versions have been suggested.,Some of the major distinctions include [consonantal], [sonorant], [nasal] and [voiced]

53、. The feature [consonantal] can distinguish between consonants and vowels, so all consonants are [+consonantal] and all vowels [–consonantal].,[sonorant] distinguishes between what we call obstruents (stops, fricatives

54、and affricates) and sonorants (all other consonants and vowels), with obstruents being [–sonorant] and others [+sonorant]. [nasal] and [voiced] of course distinguish nasal (including nasalized) sounds and voiced sounds

55、respectively.,These are known as binary features because we can group them into two categories: one with this feature and the other without. Binary features have two values or specifications denoted by ‘ + ’ a

56、nd ‘ – ’ so voiced obstruents are marked [+voiced] and voiceless obstruents are marked [–voiced].,The place features are not binary features – they are divided up into four values: [PLACE: Labial], [PLACE: Co

57、ronal], [PLACE: Dorsal], and [PLACE: Radical], which are often written in shorthand forms as [Labial]p, [Coronal]p, [Dorsal]p, and [Radical]p.,A useful feature for consonants not found here is [±spread] (for ‘spr

58、ead glottis’), which distinguishes between ‘a(chǎn)spirated’ and ‘unaspirated’ voiceless obstruents. Aspirated sounds are [+spread] and unaspirated sounds are [–spread]. Now we can represent the rule that governs the unaspir

59、ation of /p/ after [s] in terms of features:,,This is a more general rule, which also applies to /t/ and /k/. It means that /p, t, k/ ([–voiced, –cont]) are all unaspirated ([–spread]) after [s] and aspirated ([+spread])

61、, decided, guided,The regular past tense form in English is pronounced as [?] when the word ends with a voiceless consonant, [?] when it ends with a voiced sound, and [??] when it ends with [?] or [?].,5. Suprasegmentals

62、,Suprasegmental features are those aspects of speech that involve more than single sound segments. The principal suprasegmentals are: SyllableStressToneIntonation,5.1 The syllable structure,σ Onset

65、 the degree of force used in producing a syllable. In transcription, a raised vertical line [?] is often used just before the syllable it relates to. A basic distinction is made between stressed and unstressed syllables

66、, the former being more prominent than the latter, which means that stress is a relative notion.,,At the word level, it only applies to words with at least two syllables. At the sentence level, a monosyllabic word may b
