The interface between syntax,
prosody, and information structure:
What we can learn from L2 speech
Maria Luisa Zubizarreta
University of Southern California
October 2009
The grammatical relevance of
discourse-based distinctions.

The focus-presupposition divide


The new-given information divide


Grammatically encoded in terms of a
quantificational structure
Grammatically encoded in terms of anaphora
The topic-comment divide; e.g.
categorical vs. thetic statements

Grammatically encoded in terms of predication.
Grammatical identification
of focus

Scope of focus identified via:

Nuclear Stress --rhythmically most
prominent word in sentence --e.g. Germanic and
Romance.

Prosodic phrasing --e.g. Bengali (Hayes & Lahiri
1991), Korean (Jun 1993), Chitumbuka (Downing 2006) ,
French (Féry 2001).

Morpho-syntax: syntactic position and
morpho-syntactic markers (e.g. Chinese, WestAfrican languages).

Combination of above mechanisms.
Nuclear Stress and Focus.

The focused constituent must contain the
word with NS (Chomsky 1971, Jackendoff
1972).

NSR generates unmarked patterns, i.e.
patterns compatible with wide focus.
Q: What’s new?
A: John broke his leg. vs.
*John broke his leg
Marked prominence patterns:
deaccenting & NS-Shift
patterns.
 In English (& other lgs), NS aligns with
the Nuclear Pitch Accent (NPA): the last
PA in the Intonational Phrase
 In English, given information gets
deaccented (PA deletion or reduction)
 If deacc constituent is contained within
the focus, NS-Shift applies:

Words with no PA are less prominent than
words with PA (in English)
“Given” within the assertion
“Givenness”: explicit mention.
Q1: Why are you buying that old stamp?
A1: Because I [foc collect stamps].
 “Givenness” inferred from context (Ladd

1980,1996)
Q2: Why didn’t you read the article I
gave you?
A2: I [foc can’t read German]
Non-asserted “Given”:
Narrow focus cases
Wide focus:
Q1: What’s new?
A1: [John broke his leg].
 Narrow focus:
Q2 :Who broke his leg?
A2: [foc John ] broke his leg. (VP deacc)

Domain of Nuclear Stress.
A Caveat
Nuclear Pitch Accent aligns with NS.
 In core cases, domain of NS is the
sentence (= Intonational Phrase or InP)
 Symmetry “Sentence = InP” can be
distorted by phonological weight and
length, giving rise to “rephrasing” &
“restructuring” of NS domain.
 Core cases: primary linguistic data for
acquisition.

Determining Nuclear Stress.
Different Views.

Syntactic approaches:
NSR applies directly to the syntactic
structure: Chomsky & Halle 1968, Cinque
1993, Kahnemuyipour 2004
 NSR applies to a “metrically interpreted”
syntactic structure: Halle & Vergnaud 1984,
Zubizarreta 1998, Zubizarreta & Vergnaud
2003, Nava & Zubizarreta 2009, to appear.

Determining Nuclear Stress.
Different Views.

The prosodic phrasing approach (Selkirk
1986, Nespor & Vogel 1986):
Phonological phrase derived from syntactic
structure via mapping algorithms
 Phrasal stress assigned to (right or left)
edge of phonological phrase.
 NS identified as the stress on the last
phonological phrase.

Nuclear Stress: the relevance of
syntactic structure

Adjunct-argument distinction in
Germanic sentences and compounds
(1) a. Hans hat an seinem Papier gearbeitet.
Hans has on his
paper worked
b. Hans hat in seinem Büro gearbeitet.
Hans has in his
office worked (Krifka 1984)
(2)a. tree-eater ‘someone who eats trees’
b. tree-eater ‘someone who eats on a tree’
(3)a. toy-factory ‘factory that makes toys’
b. toy-factory ‘a toy that is a factory’
( Fudge 1984, Selkirk 1984, Giegerich 2004, among others )
Non-Phrase final NS in
Germanic

Unmarked stress patterns with nonsentence final NS (esp. with unacc verbs)
(1) Why are you so happy?
My friend arrived.
(100%)
(2) Why are the kids looking outside?
A rabbit appeared. (100%)
(3) What was that crashing sound?
A window broke.
(100%)
(Schmerling 1976, Selkirk 1984, 1995, Gussenhoven 1984. Exs
from Nava & Zubizarreta’s experimental protocol (in press)).
Nuclear Stress: final vs. nonfinal NS in intransitives
 NS on the subject
 The pizza arrived.
 SV
S
Adv V  NS rightmost (Gussenhoven
1984)
 The
pizza quickly arrived.
Nuclear Stress: the relevance of
semantico-pragmatic factors
Germanic
 Variability (esp. with unegartive verbs)
(4) How did the party end?
A guest sang. (57%)

A guest sang. (43%)
Pragmatics (predictability & noteworthiness)
(5) Why are those children screaming?
Because a dog is barking.
(71%)
(6) Why does everybody look so surprised?
Because a dog is singing.
(81%)
(Exs. from Nava & Zubizarreta’s in press)
Categorical vs. thetic marking
via NS

Categorical/thetic distinction can be marked
via NS in Germanic (Sasse 1987).
 Unacc (due to their lexical semantics) tend
to be construed as thetic (or eventive): SV
 Unergatives tend to be variable: SV
(thetic) or (SV) (categorical)
 Pragmatics (predictability or
noteworthiness) can influence construal
of statement as categorical or thetic
P-phrasing: categorical vs. thetic

No one-to-one correlation between NS
placement and p-phrasing
(S V) ‘my friend arrived’ (unacc)
 (S) (V) ‘a guest sang’
(uneg)
 (S V)
‘a guest sang’
(unerg)


Stress retraction: (ANne Marie BYcicled)
Cf. Inkelas & Zec 1993
Nuclear Stress:
Germanic vs. Romance

Germanic: flexible NS
sentence-final and non-sentence final NS
patterns.
 variability in the positioning of NS in certain
structures (SV intransitives)


Romance: rigid NS (e.g. Hualde 2006, 2009,
Sosa 1999, Zubizarreta 1998 for Spanish)
phrase-final NS patterns
 no variability

Theticity marking:
Germanic vs. Romance

Categorical / thetic distinction encoded
syntactically in Romance, ie. via word in Span
 VS (thetic) vs. SV (categorical)
 Theticity can also be expressed syntactically in
English (there-construction).
 Cross-linguistic difference remains (not
explainable by discourse-considerations).
 There’s a dolphin swimming.
 Hay un delfin nadando.
The NSR: our view.
A grammatically encapsulated algorithm.
 Generates “unmarked” rhythmic patterns
–compatible with wide focus.
 In Germanic, NSR generates variable
patterns in certain structures.
 Speaker chooses a particular NS
pattern depending on:
 Sentence thetic or categorical;
information highlighting

Cross-linguistic differences:
Prosody of function words
categories
 Prosodic nature of function words at the
heart of the Romance/Germanic NSR
parameter.
 Germanic: function words may be
unstressed/reduced  functional
categories may be metrically invisible.
 Spanish: function words not reduced
 functional categories metrically
visible.
The prosodic status of
(semi)-function verbs.
Non-lexical verbs are intrinsically
unstressed/reduced (Inkelas & Zec 1993)
 Becomes metrically strong: (Altenberg p. 172-3)

If clause final. “Wherever she was, always a
letter came through, asking how she was.”
 If followed by deaccented anaphoric
complement. I […] asked him how he was
doing it.”
 If emphatic. “It had to be a well.”

A two-layer NSR.
NSR applies to a metrically interpreted
syntactic tree & assigns Strong vs. Weak
to sister nodes (Liberman 1975).
 Given two metrical sister nodes A and B:

(i) If A is a head and B is its argument, assign
S(trong) to B. (specific NSR)
(ii) Otherwise, assign S(trong) to the rightmost
constituent node (general NSR).

Anaphoric Deaccenting
 A-deaccenting:
 pitch-range reduction
 interacts directly with discourse
 not gramm constraint
 variable & gradient

Output of A-deacc (as well as Emphasis)
affects metrical structure  NS-Shift.

non-pitch accented syllables always
metrically weaker than pitch-accented ones

Recapitulation

2 distinct types of phenomena:
Type 1: Phenomena to be described at an
abstract grammatically-encapsulated level
(e.g. NSR)
 Type 2: Phenomena to be described at the
interface level between signal & discourse
(e.g. A-deaccenting, Emphasis)

A-deacc: English vs. Spanish

Spanish does not use A-deacc
No grammatical reason
 Rather, stylistic reasons.


Spanish uses other grammatical
resources instead, such as cliticization
and dislocation.
Implications.

Typological differences:
Type 1: deeply rooted in the grammar of the
language (e.g. type of NSR depends on the
metrical status of functional categories)
 Type 2: merely stylistic; it has no
grammatical “raison d’être”.


Hypothesis: Type 2 is more amenable
to change than Type 1.
L2 Speech: ideal testing
grounds

L1 Spanish/L2 English speech ideal
testing grounds (Nava & Zubizarreta 2009, 2010;
Zubizarreta & Nava to appear)

L1 & L2: Grammars in competition (Yang
2003)
Dominant L2 (L2 “acquired”)
 Dominant L1 or oscillation between L1 and
L2 grammar (L2 “not acquired”)

Our L2 study
Production of target-like Germanic NS
(as a measure of acquisition of Germanic
NSR)
 Production of vowel reduction (as a
measure of metrical invisibility)
 A-deaccenting & NS-shift in wide focus
and narrow focused contexts.

Studies on L2 rhythm

Studies on L2 rhythm: e.g. Carter 2005, White
& Mattys 2007, Carter 2005, Gut 2003
 Gut 2003 investigated L1 rhythmic influence
on vowel duration across populations.

Compared L1 Romance (French, Italian,
Romanian) and L1 English learners of L2 German.

English: general vowel reduction in unstressed syllables.
German: vowel reduction in inflectional morphemes & in
syllables in final position in lexical words

Romance: no vowel reduction.

Gut 2003: L2 vowel duration

Gut’s results:
L1 Romance native populations showed
evidence of L1 transfer via their low level of
vowel reduction in L2 German.
 L1 English natives reduced vowels in more
contexts in German than German natives.

Acquisition of Germanic NS

Acquisition of Germanic NS patterns involves
two aspects: the formal and the functional
 acquisition of metrical invisibility of
functional categories (i.e.Tense)
 measured by production of reduced Aux
 Acquisition of NS as marker of theticity
 measured by distinction between
unacc. (thetic) and unergatives
(variable).
Timing of acquisition of
Germanic NS & Aux-reduction
Acquisition of metrical invisibility of Aux
is a necessary (although not sufficient)
condition for acquisition of Germanic
NSR.
 Prediction: acquisition of Auxreduction should precede acquisition
of Germanic NS.

Timing of acquisition of
Germanic NS vs. A-deaccenting
Acquisition of Germanic NS requires
“restructuring” of deep-rooted L1
grammatical properties
 Acquisition of A-deacc requires a stylistic
change (no grammatical restructuring
involved)
 Prediction: Acquisition of A-deacc
should precede acquisition of
Germanic NS.

Summary & conclusion.

All +NS L2ers produced more than 75% of Aux
Red, but also significant number of –NS L2ers
have 75% or more of Aux Red.
 Acquisition of Aux Red precedes
“acquisition” of Germanic NS.
 +NS L2ers produce signif. more SV than SV
patterns with unacc. than with unergatives.
 +NS L2ers have acquired the function of
Germanic NS (as marker of theticity).
English: Anaphoric-deaccenting
& NS-shift (wide focus contexts)


In English (but not in Spanish), “givenness” can
trigger significant pitch-reduction at the grammardiscourse interface.
If deaccented material includes NS-bearing word, NSShift applies (shifting NS onto metrical sister)


Why are you buying that old stamp?
Because I collect stamps. (75%)
Why are these notebooks missing their covers?
Because I’m drawing pictures on the covers. (88%)
Anaphoric-deaccenting
& NS-shift (wide focus)
Q&A protocol contained
 4 transitives with “given” DO
 4 ditransitives with “given” PP
 Above chance-level production of Aanaphoric deacc & NS-shift:
 16 (out of 27) High Prof. learners
 3 Intermediates
 Recall: only 9 High Prof. learners
produced unmarked Germanic NS.

English: Anaphoric-deaccenting &
NS-Shift (narrow focus).

Aligning NS with narrow focus via Adeaccenting & NS-Shift:
Who was crying?
An actress was crying.
 Who arrived?
My friend arrived.
 Who broke his leg?
A boy broke his leg.

Summary & Conclusion.

A-deacc is acquired earlier than
Germanic NSR (i.e. easier to acquire)

Lers switch to A-deacc especially early
when it is required for focus-identification
Results support our expectations
regarding ordering of acquisition.
 Anecdotal evidence: English influence
on deacc patterns in Eng-Span
bilinguals.

Germanic NS in compounds vs.
sentences. Future research.
Germanic NS at the phrasal level.
 Requires acquisition of metrical
invisibility of functional categories
 Germanic NS in compounds.



Metrical invisibility of functional categories
irrelevant.
Expectation: Acquisition of Germanic
NS in compounds precedes acquisition
of Germanic NS in phrases.
Germanic NS in compounds vs.
sentences. Future research.

Germanic NS should be acquired earlier
in compounds than in sentences.


No correlation between Aux reduction &
Germanic NS in compounds.
Prosodic patterns in compounds
serve as cue for acquisition of the
formal part of Germanic NS; i.e.
trigger switch from L1 to L2 algorithm
