Abstract:
Temporal effects of focus in Swedish were studied in short sentences
with systematic variation of the length and prosodic pattern of target
words in different syntactic positions. Generally, focus caused an
average increase in word duration of about 25%. Variations of word
length, stress, or word accent pattern did not produce any systematic
effects on the amount of lengthening of the target word, but the lengthening
varied considerably between speakers and different positions in the
sentence. The most extensive lengthening occurred in combination with
the insertion of a boundary after the word in focus in those cases
when the word preceded a strong syntactic boundary. Within words,
stressed syllables were lengthened most, and lengthening of a primary
and following secondary stressed syllable was equal to that of a single
primary stressed syllable. As unstressed syllables were also affected,
the domain of focal lengthening is assumed to be the word.

Abstract:
This paper presents results from the analysis of segmental duration
in French in three different speaking styles, (a) 'reading'; (b) 'news
broadcast' ; (c) 'spontaneous interview'. A ten minute corpus was hand
segmented and labelled using six accent categories (i) unstressed (ii)
word-initial (iii) emphatic word-initial (iv) word-final (v) intonation
unit final before non-terminal boundary (vi) intonation unit final
before terminal boundary. Results show that when different accent
types and different speaking styles are taken into account there is
no uniform lengthening of prosodic constituents in French, whether
the syllable or some other suprasegmental unit is taken as the domain
for lengthening. Instead differential lengthening is observed consistently
with essentially greater lengthening towards the beginning of the syllable
for initial prominence and greater lengthening towards the end of the
syllable for final prominence. The degree of the different types of
lengthening was moreover significantly different across the speaking
styles.

Abstract:
The prosodic features of filled pauses (fillers) and self-repair are
investigated with a view towards the detection of disfluencies. First,
we compare the prosodic features of typical fillers and their fluent
homonyms using read sentences of identical phoneme sequences. It is
confirmed that the fillers (1) have at least 2 times longer duration
than their non-disfluent counterparts, (2) tend to be followed by definitely
longer pauses, and (3) have much smaller movement in their pitch contours.
Then, the spontaneous fillers segmented out from a dialogue corpus
are also analyzed. The same tendency is confirmed, but some samples
lie halfway between the read fillers and their fluent homonyms. The
abruptly cut-off endings in the self-repair are also analyzed by comparing
with the ordinary endings of words. It is found that a short phoneme
ending coupled with a relatively short succeeding pause indicates the
abrupt cutoff.

Abstract:
This paper proposes a computable, tone-driven method to model phrasal
pitch movements in standard Chinese by (1) formulating physical constraints
for phonetic control mechanisms, (2) defining four phrasal tones quantified
by model parameters for generating phrasal tunes, and (3) forming phrasal
pitch movements by mapping lexical tones onto phrasal tunes. Several
experiments confirm the method's validity. The proposed method is an
effective component technology for analyzing, synthesizing and understanding
spoken Chinese intonation.
