ENG 528: Language Change Research Seminar Sociophonetics: An Introduction Chapter 10: Sound Change And Related Articles Linguistic vs. Social Factors Two common assumptions: 1. They can be distinguished 2. They perform different functions: a) linguistic factors determine how sound changes get started b) social factors determine how they spread Are they really separable? Issues from Weinreich et al. (1968) Well return to these when we read the article later this semester: 1. Constraints 2. Transition 3. Embedding 4. Evaluation

5. Actuation Teleology The word means happening for a purpose Is sound change ever teleological, or does it always happen by accident? Ohala is staunchly against any teleological account of sound change, but doesnt that go against sociolinguistic findings that adolescents adopt changes as social markers? Ease of Articulation Also called economy of effort This idea goes back a long, long way (19th century) It says that changes that make things easier to pronounce are favored It can be teleological if you assume that saving effort is a goal for speakers: increased efficiency Conditioned changes usually involve ease of articulation: assimilation, deletion especially Lenitions of various kinds also involve ease of articulation

Clarity The opposite of ease of articulation is clarity Clarity involves making things easier for addressees to understand That would mean expending a greater effort when speaking Various fortition processes qualify as improving clarity Ease vs. Clarity Various linguists, particularly Maurice Grammont, have seen ease of articulation and clarity as two forces that balance each other Maximal Dispersion Related to the clarity position Notion that sounds tend to become evenly dispersed in the acoustic space

Moultons (1962) demonstration of how it applied to long low vowels in Swiss German is an interesting case Push chains and pull chains are consequences of maximal dispersion Martinet (1952), Function, structure, and sound change (1) Martinet notes that the causes of morphological, syntactic, and lexical change are often transparent What about phonological change? Its causes are more opaque Martinet (1952), Function, structure, and sound change (2) He talks about the development of allophones (conditioned shifts), e.g. OE ceosan, freosan (modern choose, freeze) house/houses, louse/lousy, loss/lose, etc., in which /s/>[z]. In this case, the phonetic explanation is obvious: voiceless consonants often become voiced between vowels (assimilation)

But what Martinets really interested in is when a whole phoneme shifts. How does that happen? That leads him to chain shifts Martinet (1952), Function, structure, and sound change (3) pp. 6 & 19, hes critical of the slot-filling approach of functionalists In its place, he talks about margins of security, which suggest perceptual factors That is, when one sound shifts out of the way, chance deviations would no longer conflict with communicative needs This would allow the range of dispersion to expand into the void Martinets explanation is compatible with Ohalas aversion to teleology Martinet (1952), Function, structure, and sound change (4) Note the emphasis on push vs. pull (drag) chains Its still a popular topic today, though in my

opinion an overblown one On p. 11, he says that they can be hard to tell apart In fact, Im not sure there is a real difference in practice much of the time Martinet (1952), Function, structure, and sound change (5) discusses functional loadthe notion that certain oppositions are more important than others. E.g., there are more minimal pairs for /p/-/b/ than for //-/ / or //-// in English In contrast to the traditional approach to functional load, he says that functional load is dependent on orders and serieswhat are essentially phonological features (e.g., voiced/voiceless)not on individual contrasts This relates to the notion of economy of gestures Martinet (1952), Function, structure, and sound change (6) Holes in the pattern: he says that they tend to be filled. Its unlikely that youd find a

pattern like this: p t k b d A new /g/ would be likely to develop. Well, maybe Apparently, there are some languages with that stop inventory. Martinet (1952), Function, structure, and sound change (7) He shows how this concept applies to Hauteville vowels. Here he seems to emphasize articulation as opposed to perception He then goes into a discussion of why gaps in the system are ubiquitous: e.g. nasal fricatives are hard to pronounce; nasals can be hard to distinguish from each other (hence // is often absent) Phonetic factors lead to some asymmetries. E.g. its easier for [] to turn into a stop than for [f] or [s] to do so Economy of effort also comes up Lindblom (1986), Phonetic universals in vowel systems (1) The Crothers study that he mentions was a

comparison of the sound systems of 209 languages, with a comparison of how many languages had a certain sound [a], [i], and [u] are the most common; [], [o], [], [e], and [i] show up next most often (see table 2.2 on p. 16) Lindblom (1986), Phonetic universals in vowel systems (2) Principle of Maximal Contrast: it should sound familiar from Martinet On p. 21 (stamped as p. 392), Lindblom says that vowel systems tend to evolve to maximize perceptual contrast, or at least to provide sufficient contrast Why? to ensure speech intelligibility under a variety of conditions and disturbances. (p. 21) He says what the problem with functional load is: it cant be quantified Lindblom (1986), Phonetic universals in vowel systems (3) After that, he goes into the math used in an earlier study, Liljencrants & Lindblom (1972); dont worry about the mathjust note that Liljencrants & Lindbloms formula predicted

small vowel systems better than large ones Lindblom then goes into a discussion of auditory systems: mels, Bark, Fletcher-Munson curves, SPL (sound pressure level) Dont worry about the math here, either. The point is that he got better results this time by paying attention to perceptual factors of the auditory system: 1. He used Bark 2. He noted masking effects (low-frequency sounds mask high-freq. sounds more than vice versa) 3. He noted the nonlinearity of frequency response, which decreases the influence of lower frequency components of the signal 4. He found that loudness scales (phones, sones) were useful He also mentioned formant levels. Basically, the general amplitude of a formant is more important than exactly where its peak is. (This is related to the issue of whether listeners identify vowels by peak-picking of formants or by spectral prominence. Evidence suggests the latter.) Lindblom (1986), Phonetic universals in vowel systems (4) Lindblom (1986), Phonetic universals in vowel systems (5) Maximum vs. sufficient contrast: it may explain a variety of vowel systems, especially large ones

That is, Lindbloms formula still didnt predict the composition of large vowel systems perfectly, so maybe sufficient distances between vowels, not optimal distances, are good enough Note that phonetic pressures can outweigh social factors (pp. 37-38) in shaping vowel systems Lindblom (1986), Phonetic universals in vowel systems (6) Lindblom mentions Ohala with regard to featureschild language learners learn to focus on particular cues (Ohala wondered whether that worked for consonants but not for vowels; Lindblom suggests that it does work for vowels) Also note that he says at the end that articulation plays a role, too difficult articulations are rare Overall, Martinet seemed to emphasize production while Lindblom emphasized perception Lindblom doesnt take historical accident into account; it can explain peculiarities of vowel systems, such as why one language as a high back unrounded vowel while another has a high front rounded vowel (both of which fill the space between [i] and [u]) and why some 7vowel systems have a vowel between [i] and [u] and others dont Problems with Maximal Dispersion

Mergers occur Some contrasts represent much less than maximal dispersionand such minimal contrasts are actually pretty common across languages, e.g., English // & /f/, German // & [], Turkish /], Turkish // & [], Mandarin [t] & [] Languages dont maximize contrasts to the fullest extent, by adding secondary articulationshere we come back to economy of gestures and to sufficient, not maximal, dispersion Problem with Ease vs. Clarity No predictive power Linguists can always attribute changes to them hindsight, but they cant predict when a change will happen based on them On the other hand, is that really a problem if sound change is probabilistic, as Ohala says? Ohalas Misperception Model Hes careful to note that certain changes are production-based, such as

tonogenesis or spontaneous nasalization However, many others are perception-based, such as [kw]>[p], and [kj] or [pj]>[t], and lowering of nasal vowels One example he likes to cite is fronting of [u] next to coronals, as in Tibetan (e.g., Ohala 1981) coarticulation speakers target: /ut/ actual realization: [y(t)] listener produces [y]

listener interprets as /y/ John J. Ohala (1993), The phonetics of sound change (1) On p. 238, he notes that sound change can result from various factors, including social ones, but he says that hes interested in changes that are widely attested because theyre more likely to have linguistic causes He says that he wont try to answer the question Why did sound change X happen where and when it did? He sees sound change as probabilistic, not absolutely predictable John J. Ohala (1993), The phonetics of sound change (2) Although he recognizes both production-based and perception-based kinds of change, he considers the listener the key player in both kinds On pp. 246-47, he explains how it has to be

language learners (either children or adult L2 learners) who misinterpret what they hear That view is open to question, as well see later. That is, language learners undoubtedly produce some innovations, but do they produce all of them? John J. Ohala (1993), The phonetics of sound change (3) Ohala emphasizes the difference between the phonetic target (=competence) and the actual production (performance) He says that listeners can do one of three or four things: 1. Correction: Listeners correctly recover the intended target (perceptual normalization) 2. Hypo-Correction: The listener is unable to perceptually adjust. This leads to assimilation, as well as to misperceptions like kw>p 3. Hyper-Correction: The listener adjusts perceptually when theyre not supposed to. This leads to dissimilation. a) Ohala used the example of Grassmanns Law, e.g. PIE *bhandh>bandh in Sanskrit and Greek; b) he also mentions Latin familialis>familiaris, populalis>popularis (cf. liberalis, mortalis)[l] and [r] are especially prone to this. We have some words in English such as caterpillar, surprise, governor, temperature, reservoir, and veterinarian in which the first /r/ is commonly lost even in r-ful

dialects John J. Ohala (1993), The phonetics of sound change (4) Ohala thinks that vowel dispersion can account for misperception; psychological tests have shown that people think that similar but different objects are more different than they really are, and he thinks that this notion could be applied to the fact that vowels seem to repel each other in vowel space. This would be a case of hyper-correction John J. Ohala (1993), The phonetics of sound change (5) On p. 268, about sociolinguistic factors, he says: At their best, they are accounts of why these changes spreadbecause at any given time all languages are flooded by all applicable mini-sound changes. This sounds appealing; dont social groups pick what sound changes they want to identify with? It would also explain why its phonetically favored changes that take hold But doesnt that go against most sociolinguistic findings, that certain people deliberately innovate?

Anthony Kroch (1978) tried to find a way of justifying these conflicting factors (sociolinguistic findings vs. the fact that only phonetically favored changes occur). He theorized that phonetic factors are always at work producing new sound changes, but that the high socioeconomic groups actively repress these changes Boersmas response to Ohala Boersmas name ought to ring a bell He said that [] is expected to be perceptually most similar to [k], but [] is more likely to shift to [d] or [] Hence languages tend to preserve distinctions, which is teleological Lindblom, Guion, Hura, Moon, and Willerman (1995), Is sound change adaptive? (1) Background: H&H Theory Continuum from clearly enunciated to poorly enunciated speech

Hyper-speech: clearly enunciated Hypo-speech: poorly enunciated (These terms are not to be confused with Ohalas hypercorrection and hypocorrection) e.g. The next word is _____. Here, youd have to enunciate carefully A stitch in time saves ______. Here, you dont have to enunciate carefully because the listener knows what to expect You enunciate only as carefully as you need to in order to get your message across; otherwise you default to low-cost behavior The hyperspeech/hypospeech continuum means that theres always going to be lots of variation present (note that this is all production-based variation). Note that they have a very monolithic approachall variation is treated as hyper/hypo (only once do they acknowledge other variation) Lindblom, Guion, Hura, Moon, and Willerman (1995), Is sound change adaptive? (2) Lindblom et al. go over one of Ohalas favorite examples, the potential confustion between /ut/-[yt] and [yt]-/yt/ They say that theres a paradox in Ohalas reasoning: How can a speaker misperceive a pronunciation and still know what word it is?

This could be circumvented by noting that Ohala cites language learners, who dont have a preconceived picture of what sounds a word consists of Lindblom et al. do mention language learners on p. 19, but only to say that sociolinguists think sound change happens with older kids (competent adults) Lindblom, Guion, Hura, Moon, and Willerman (1995), Is sound change adaptive? (3) They say that theres only one way to resolve the paradoxto propose that listeners have two modes: WHAT mode: focus on whats being said HOW mode: focus on how its being said Then they said that the HOW mode is where sound change happens (here they agree with Ohala) Finally, they say that speakers can go into HOW mode, notice unusual pronunciations, and manipulate them (unlike Ohala, who focuses on misperception) Lindblom, Guion, Hura, Moon, and Willerman (1995), Is sound change adaptive? (4) Some of their arguments are assailable. The German example (p. 21) could also be explained by fricatives being more perceptually

salient. The Guion (1994) experiment on greater length of unfamiliar words could also be explained as a product of familiarity it takes longer to recall an infrequently used word After going through a bunch of examples, they get to sociolinguistics (p. 28). Here, they tie their idea of selective adoption of pre-existing variants in with the sociolinguistic notion of solidarity This would explain why its phonetically favored variants that spread: listeners who are using variants for peer identification can choose only from variants that already exist, and those variants are formed by phonetic factors (we said the same thing regarding Ohala) Ohala vs. Lindblom et al. issue stance of Ohala (1993) stance of Lindblom et al. (1995) Why does variation occur in the Variations are always present

Variations are always present first place? because of coarticulation and because speakers adjust their own numerous other phonetic factors. articulation according to the communicative needs of listeners, enunciating more carefully (hyperspeech) or less carefully (hypospeech). How do sound changes originate? Many (not all) sound changes Variations originate teleologically originate by misperceptions:

for a purpose. (They maintain, listeners (usually language learners) though, that hypospeech is not make mistakes in reconstructing the teleological.) target pronunciation of a sound. Ohala vs. Lindblom et al. issue stance of Ohala (1993) stance of Lindblom et al. (1995) Whats the purpose of sound The origin of sound changes is non- Speaker/listeners test natural change? teleologicali.e., its not purpose- variations for their communicative

driven. Speakers dont intend (even value. subconsciously) to make speech easier to pronounce or easier to understand, or to make the grammar simpler. How are sound changes Sound changes may spread Speaker/listeners deliberately take propagated? teleologically because social factors advantage of variations and select such as prestige provide a certain variants to use as social motivation. symbols.

Browman and Goldstein (1991) they agree with Lindblom et al that production, not perception, is primary they agree with Ohala that change is accidental, not deliberate Blevins (2004), Evolutionary Phonology: The Emergence of Sound Patterns She started out life as a generative phonologist CCC model: CHANGE = misperception, a la Ohala CHANCE = reinterpretation of an ambiguous signal; some metatheses might qualify (e.g., brid>bird, drit>dirt) CHOICE = processes such as undershoot result in multiple realizations, and listener chooses a different one from what the speakers underlying

form was (e.g., off>of) Origin and Actuation In contrast to the authors weve been looking at so far, Labov said that origin and spread cant be separated His reasoning was that a change isnt a change until the population using it begins to increase My objection to Labov: why cant an innovation by one person be a change? Romaines objection to Labov: it obscures the actual origin; i.e., actuation wouldnt be such a riddle if you didnt exclude individual innovations My reasoning for why origin and spread cant be separated: linguistic factors make any potential change occur part of the time in various peoples speech, so by the time the number of people using the change starts to increase, there will already be lots of people who do it at least sometimes How compatible are the theories with sociolinguistic findings? Sociolinguistic findings offer clear evidence that children adopt features from their peers and may even exaggerate them

The evidence suggests that children do that deliberately for identity reasons (however, cognitive experiments are needed to prove that its deliberate) That, in turn, suggests that Lindblom et al. and Blevinss CHOICE explain sound changes better However, misperception could still be plausible and might explain how the exaggeration pushes sound changes to new levels Questions for Discussion 1. How would you go about tracking potential sound changes before they take on social identity functions? 2. What are some experimental ways you could test whether speakers deliberately innovate or innovate by misperception? Does your choice of method depend on the kind of variable youre examining? Labovs Theories about Sound Change [i] [u]

Pe rip he ral Peripheral ral he rip Pe A central assumption in Labovs theorizing is that the vowel space is divided into peripheral and nonperipheral tracks He even proposed [peripheral] as a phonological feature Non-peripheral

[a] Labovs Background Evidence In Labov, Yaeger, & Steiner (1972), a systematic survey of known vowel shifts around the worlds languages (actually, mostly in European languages) was conducted LYS then synthesized the recurrent patterns they found into a series of principles Labov has reformulated these principles in various ways in subsequent publications (Labov 1991, 1994, 2001; Labov, Ash, & Boberg 2006) Labovs Principles of Vowel Shifting (1) The first three principles are the basic ones: Principle I. In chain shifts, tense nuclei rise along a peripheral track (Labov 1994:176); reformulated from In chain shifts, long vowels rise (1994:116). Principle II. In chain shifts, lax nuclei fall along a nonperipheral track (Labov 1994:176); reformulated from In chain shifts, short vowels fall (1994:116). Principle IIA. In chain shifts, the nuclei of upgliding diphthongs fall (1994:116). This principle accounts, e.g.,

for the lowering of Middle English and Middle High German /u/, after diphthongization to [u], through the stages [ou>u>u>au]. Labovs Principles of Vowel Shifting (2) Principle III. In chain shifts, tense vowels move to the front along peripheral paths, and lax vowels move to the back along non-peripheral paths (1994:200). Principle IV. In chain shifting, low non-peripheral vowels become peripheral (the lower exit principle; 1994:280). That is, a vowel that falls will eventually hit bottom and enter the peripheral space when it reaches an [a] value. Principle V. In chain shifting, one of two high peripheral morae becomes non-peripheral (1994:281). This principle accounts for the diphthongization of long high vowels e.g., /u/ shifting to [u]. Labovs Principles of Vowel Shifting (3) Principle VI. In chain shifts, peripheral vowels rising from mid to high position develop inglides (1994:284). This accounts for shifts such as /o/ becoming [u]. Principle VII. Peripherality is defined relative to the vowel system as a whole (1994:285).

Principle VIII. In chain shifts, elements of the marked system are unmarked (1994:288). This principle is designed for languages that have a series of creaky or nasal vowels, which count as the marked system. By Principle VIII, such vowels would tend to lose the secondary articulation. Objections to Labovs Principles Can be applied only to languages with a tense/lax or long/short distinctionLabovs answer is that marked series of vowels can function like tense vowels Exceptions to the principles (Cox 1999): Labov says that his principles werent meant to be exceptionless, and Coxs example is problematic anyhow Is peripherality the motivating factor (never actually stated by Labov, but certainly implied) or just an incidental by-product of shifting? See diagrams on next slide Peripherality: Motivator or By-Product of Vowel Shifting? Motivations for the Principles

Theoretically speaking, this may be a bigger problem for the principles than any of the objections listed earlier Youve got to have a motivationin science, theres got to be a reason for everything! Labov has provided a possible explanation for Principle III (asymmetry of articulatory space) Principles IV and VII dont require much explanation The other principles are more problematic Gussenhoven (2007) offered an explanation for Principles I and II, and I offered one (2003) for Principle V, but nothings been tested Chain Shifting Patterns across Languages Pattern 1: Principles I & IIA, with help from V; a long high vowel diphthongizes and lowers, another one rises to fill its place Pattern 2: Principles I, II, & III; fronting & raising of long vowels, falling of short vowels Pattern 3: Principles I & III; fronting of back vowel(s) (usually just /u/), raising of other back vowels to fill in behind Pattern 4: Peripheral and non-peripheral vowels switch places

Shift for Canada, and its been found in parts of the U.S. with the low back merger since then III KIT II DRESS II I TRAP II, IV LOT=THOUGHT Mergers Proving that somebody really has a merger can be a problem The flip side, which some sociolinguists forget, is that it can be equally hard to prove that somebody makes a distinction In speech production data, you have to make sure that tokens from the two classes occur in comparable phonetic contexts In a near merger, a speaker says they dont make a distinction

when in fact they do However, speakers will sometimes erroneously report that they make a distinction when they dont Various cognitive experiments have been devised to test for mergers in speech perception; we covered them in chapter 3 Principles of Mergers (after Labov 1994) 1. Mergers are irreversible by linguistic means (1994:311 Gardes Principle) 2. Mergers expand at the expense of distinctions (1994:313Herzogs Principle). Apparently for cognitive reasonsthe simpler configuration is cognitively easier for language learners. Both can be violated by social factors, but only by social factors a) demographic swamping b) pressure from prestige forms Mechanisms of Merger (1): Merger-by-Approximation Two classes get closer together until the distance between them disappears Its not necessary for both classes to moveonly one of the

classes has to move Time 1 Time 2 Time 3 /a/ /a/ /a=b/ /b/ /b/ Mechanisms of Merger (2): Merger-by-Transfer Words are transferred from one class to another until the losing class gets bled to death Time 1 Time 2 Time 3

Division between plantation (/ai/ split, r-lessness) and

non-plantation (monophthongal /ai/ in all contexts, rfulness) regions. 2. Southern drawl. Much remarked on, but little studied. 3. Southern Shift. Weve been over it already. 4. Front-gliding /o/ and /u/: This recent pattern has spread widely in the Southeast but seems to have started around the Pamlico Sound.

factors It immediately stirred up a firestorm in linguistics; are sound changes really exceptionless? Since then, however, there have been two challenges to it: 1. Whether morphological or syntactic factors can condition sound changes 2. Lexical diffusion: the notion that sound changes can spread word-byword through a language. Main proponent has been William S.-Y. Wang The Neogrammarian Controversy (2) Labov spent a lot of time sorting it out He concluded that most sound changes followed the Neogrammarian Hypothesis He allowed for several kinds of changes to be lexically conditioned, however (e.g., shortening/lengthening, deletions of obstruents) Propagation of Changes I wont say much about it here, but theres a bunch of terminology Note internal and external motivations for changes Weve already discussed language contact

Keep in mind what the Wellentheorie (wave model) and Stammbaum (genetic model) are; well come back to Stammbaum in chapter 12 Spatial diffusion can be hierarchical, contrahierarchical, or contagious (though both dialect geographers and sociolinguists have assumed hierarchical to be the norm) Recall what change-from-above and change-from-below are Questions for Discussion 1. How does the opposition of least effort vs. clarity relate to the controversy over the Neogrammarian Hypothesis vs. lexical diffusion? 2. What methods could be used to test Labovs principles of vowel shifting? Fun with Vowel Formant Plots 400 r i
