Page 3: Faithfulness, Registers and Lexical  Representation

Starting PointVan Oostendorp (1998) works out the idea that styles and registers of one language (informal, formal, etc. – and we include speed as well) represent related systems and not self-contained grammars. This is to

1. simplify the set of assumptions that we need on the acquisition side (avoid an “empowered” logical problem of language acquisition).

2. make inconsistent that two registers would differ like two random grammars do (on the empirical/typological side).

We produce extra evidence in support of this claim, using data of slow, medium and fast speech from the dialect of Rome and from Serbo-Croatian.

Page 4: Faithfulness, Registers and Lexical  Representation

Theoretical frameworkOT Prince and Smolensky (1993/2004): ⟶Surface forms are the result of the evaluation by

conflicting constraints that interact with one another, dependently on their ranking (a language-specific hierarchy);

⟶a grammar consists of the ordering of this universal set of constraints, and the way of accounting for any variation is the manipulation of their ranking.

Van Oostendorp (1998) suggests a principle to account for cases of register variation:→ The more formal the register, the higher ranked the

faithfulness constraints

Example 1 Allegroform: speed and the dialect of

RomeIn the dialect of Rome, speed has a clear impact on phonology. From slow to fast speech many phenomena arise. One is, for instance, the deletion/lenition of [l] followed by vowel assimilation.

We suggest that:• formal levels behave symmetrically to slow speech, • semi-formal levels behave symmetrically to medium speech • informal levels behave symmetrically to fast speech

There is a continuum between perception-oriented speech (i.e. listener-friendly) and production-oriented speech (i.e. speaker-friendly).

Deletion of [l] followed by vowel assimilation

Prepositions: /de/ “of, from” /da/ “from, to” /a/ “to”

Articles: /lo/* “themasc.sing”, /la/ “thefemm.sing”, /i/ “themasc.plur”, /e/ “thefemm.plur”

Data Sample

[slow] [de lo] [de la] [a la] [a lo][medium] [de.o] [de.a] [a.a] [a.o][fast] [doo] [daa] [aa] [ao]

[slow] [da lo] [da la] [da le] [da i][medium] [da.o] [da.a] [da.e] [da.i][fast] [doo] [daa] [dee] [dii]

*/lo/ is the article that precedes words starting with /z/, /pn/, /ɲ/, /ps/, /ʃ/, /ks/, /s/+consonant (and vowels). Elsewhere /er/.

Example 2 (from van Oostendorp 1998)

Vowel reduction in three registers of Dutch

fonologie (phonology) is pronounced:1. [ˌfo.no.lo.ˈxi] formally 2. [ˌfo.no.lə.ˈxi] semi-formally3. [ˌfo.nə.lə.ˈxi] informally

Constraint set

• Parse (F)• Reduce-1:Weak and semi-weak positions should be

schwa.• Reduce-2: Weak positions should be schwa.

All otherunstressed

postions

position

New data – Example 3Opacity, Coda-l vocalisation and a-Epenthesis

in Serbo-CroatianIn Serbo-Croatian, there is a historicized process which turns coda-l into [o].

Coda-l vocalisation /del/ → [de.o] “partnominative” /del + a/ → [de.la] “partgenitive” (It does not apply to any non-native items: kanal, rival, interval.)

There is another process which disrupts all coda clusters by inserting an epenthetic [a].

a-Epenthesis /visk/ → [visak] “pendulumnominative” /visk + a/ → [viska] “pendulumgenitive”

Page 18: Faithfulness, Registers and Lexical  Representation

Example 3 - Opacity and Registers

These two processes interact opaquely: Coda-l vocalisation bleeds the environment of a-Epenthesis. /petl/ → /petal/ → [petao] “cocknominative”

(a-epenthesis) (l-vocalisation) /petl + a/ → [petla] “cockgenitive”

Important!Fast/very informal has the transparent mapping /petl/ → [peto].

Page 19: Faithfulness, Registers and Lexical  Representation

Our contributionPotential problem: Registers are rankings of constraints i.e. OT grammars. However, informal/faster registers could, in principle, be unlearnable by themselves because, as we have seen, they rely on representations which are made available by formal/slower registers.

Solution: Other representations another language.So registers are full rankings, but not full, self-sufficient languages.

Generalization: registers are part of a broader phenomenon of related forms (e.g. speed, dialects, cognates, interspeaker variatios, etc.)

Acquisition Accomodation Principle: when speakers are building their lexicon/grammar, they rely on all the available forms.

Bottomline: representations matter (not contra RotB, rather pro RotS)

Page 20: Faithfulness, Registers and Lexical  Representation

In other words, a direct consequence of the data: what if

a register is missing? • What is the representation in a Dutch speaker who has

only ever been exposed to [ˌfonələˈxi]? But then, this speaker would have to be exposed to [ˌfonəˈlox] “phonologistinformal”?

• Can there be a Roman fast-register-only speaker? Would this speaker lack any representation of [de la]?

• How does the Serbo-Croatian “informal speaker” compute the opaque forms of the type [petao]?

Bottomline: Representations depend on the available forms.

Page 21: Faithfulness, Registers and Lexical  Representation

Beyond the primacy of the slow/formal?

• What we have seen is really part of the Dutch/Italian/Serbo-Croatian speakers’ competences.

• So it is worthwhile to move beyond the “anthropological” bias (encoded in van Oostendorp’s principle):

Slow/formal gets it right by definition:the lexicon relies on slow/formal speech. So, it is not surprising that FAITH is high in slow/formal ranking.

• But: do we need to encode that much?

Page 22: Faithfulness, Registers and Lexical  Representation

Our alternative or

On how van Oostendorop is (more) right (than he thinks)

• Every surface form (produced or perceived) participates in the construction of the underlying representation.• This clearly plays a role in the comprehension of

e.g. other dialects/sociolects (see Benders 2011).

• Due to physical properties of slow/formal speech, such forms will contain more contrast/information than other forms; these will always be closer to underlying forms.

Page 23: Faithfulness, Registers and Lexical  Representation

Residual questionsAs pointed out to us by Birgit Alber (voce), this could be a domain of Output-Output relations. So, do different style/register forms constitute paradigms of some sort?

• Is there cross-style uniformity?• Is there blocking from above?

• e.g. in lexicalizations, borrowings, etc.
