Does spoken language consist of sentences?
Sheer facts: Spoken language is the primary form of
language Spoken language does not contain periods,
question marks and other explicit signals of sentence boundaries
Research question: Is sentence, as a theoretical construct, as
identifiable and as basic for the primary form of language as it is (or as it is thought to be) for written language?

Sentence in spoken language
Position 1: sentence is a universal and basic unit of language Assumption typically held by not only by linguists but
also by other cognitive scientists “With no more than 50 to 100 K words humans can
create and understand an infinite number of sentences” (Bernstein et al. 1994: 349-350)
Psycholinguistics: “Sentence processing” But sentence is very far from being obvious in spoken
language
Position 2: avoidance of the issue, typical of discourse-oriented linguists If so, how could sentences become so much entrenched
in written language?

Night Dream Stories
Corpus of spoken Russian stories Speakers: children and adolescents Subject matter: retelling of night
dreamsDiscourse type: monologic narrative
(personal stories) Speech act type: declaratives

Two basic features of spoken discourse
Segmentation Transitional continuity
![Page 6: IS SENTENCE VIABLE? The 3 rd International Conference on Cognitive Science Moscow, June 21, 2008](https://reader035.vdocument.in/reader035/viewer/2022062718/56812f39550346895d94cd39/html5/thumbnails/6.jpg)

Segmentation
Elementary discourse units (EDUs) Identified on the basis of a conjunction of
prosodic criteria: Tempo pattern Loudness pattern Integral tonal contour Presence of an accentual center Pausing pattern
Speakers tend to organize EDUs as clausal units

Transitional continuity
Term by J. DuBois et al. 1992 Alternative term by Sandro V. Kodzasov:
phase Discourse semantic category: ‘end’ vs. ‘non-
end’ (=expectation of a forthcoming end) Hierarchical nature of phase End of tentative sentence – falling tonal
accent Non-end – rising tonal accent
![Page 9: IS SENTENCE VIABLE? The 3 rd International Conference on Cognitive Science Moscow, June 21, 2008](https://reader035.vdocument.in/reader035/viewer/2022062718/56812f39550346895d94cd39/html5/thumbnails/9.jpg)

Rising (“comma”)Non-end
Falling (“period”)End
If things were that easy, sentence would be uncontroversial

The problem of two kinds of falling
The existence of non-final falling may call relevance of sentence into question
However, the distinction between two kinds of falling is very systematic
The two kinds of falling: are prosodically distinct have distinct discourse functions

Prosodic criteria of the final vs. non-final falling distinction
Primary criteria:1. Target frequency band2. Post-accent behavior
![Page 13: IS SENTENCE VIABLE? The 3 rd International Conference on Cognitive Science Moscow, June 21, 2008](https://reader035.vdocument.in/reader035/viewer/2022062718/56812f39550346895d94cd39/html5/thumbnails/13.jpg)
13
Criterion 1: Target frequency band
Final falling (“period”): targets at the bottom of the speaker’s F0 range
Non-final falling (“faling comma”): targets at level several dozen Hz (several semitones) higher

Final falling (“period”): steady falling on the post-accent syllables
Non-final falling (“comma”): lack of falling on post-accent syllables, often rise of tone (V-curve)

The final vs. non-final falling distinction
A speaker’s prosodic pattern must be identified
On its basis the difference between final and non-final falling distinction can be identified with a high degree of robustness

25
The status of sentence
In the speech of most speakers final falling is clearly distinct from non-final patterns
Final intonation, expressly distinct from non-final intonation (both rising and falling), makes the notion of sentence valid for spoken discourse
Speakers “know” when they complete a sentence and when they do not
Apparently, spoken sentences are the prototype of written sentences
![Page 26: IS SENTENCE VIABLE? The 3 rd International Conference on Cognitive Science Moscow, June 21, 2008](https://reader035.vdocument.in/reader035/viewer/2022062718/56812f39550346895d94cd39/html5/thumbnails/26.jpg)
26
Functions of sentences
Ease the processing by creating intermediate informational chunks
Chafe: superfoci of consciousness
![Page 27: IS SENTENCE VIABLE? The 3 rd International Conference on Cognitive Science Moscow, June 21, 2008](https://reader035.vdocument.in/reader035/viewer/2022062718/56812f39550346895d94cd39/html5/thumbnails/27.jpg)
27
However
Identification of sentences is possible only on the basis of a complex analytic procedure
It is dependent on prior understanding of a speaker’s prosodic “portrait”
There are prototypes of final and non-final fallings, but there are intermediate instances, therefore sentencehood may be a matter of degree
A significant tune-up is necessary to apply the procedure to a different discourse type or a different language
Therefore, sentence is an elusive, intermediate, non-basic unit of language

EDUs vs. sentences: degree of variability
Unlike EDUs, sentences are highly variable
Speakers with short sentences Speakers with long sentences
equaling stories Clause chaining

Conclusions
Sentence is an intermediate hierarchical grouping between a whole discourse and an EDU (roughly, clause)
Sentence is very far away from being a basic unit of spoken language
