Spectrographic data are presented to exemplify effects of segmental reduction on utterance length, measured in terms of number of phonetic syllables per utterance. The speculation is put forward that segmental reorganization in ‘fast speech’ is partly constrained to preserve speaking rate, specified as number of phonetic syllables per unit time.

In earlier work, we have shown that articulation rate in Swedish child-directed speech (CDS) increases as a function of the age of the child, even when utterance length and differences in articulation rate between subjects are controlled for. In this paper we show on utterance level in spontaneous Swedish speech that i) for the youngest children, articulation rate in CDS is lower than in adult-...

In this paper, an algorithm performing automatic reconstruction of utterance boundaries time marks in speech database re-grabbed from DAT recorder is presented. Originally, the database was grabbed from DAT and, after down-sampling, processed at 16 kHz. Utterance boundaries were manually found, each utterance was stored to a separate file and orthographic and phonetic transcriptions were perfor...

Automatic speaker verification is susceptible to various manipulations and spoofing, such as text-to-speech synthesis, voice conversion, replay, tampering, adversarial attacks, so on. We consider a new spoofing scenario called "Partial Spoof" (PS) in which synthesized or transformed speech segments are embedded into bona fide utterance. While existing countermeasures (CMs) can detect fully spoo...


 This work presents the prosodic analysis of Parenthetical Units in spoken Italian and German within theoretical framework Language into Act Theory (L-AcT), which defines such textual units as Parentheses (PARs), i.e. devices used by speaker to add information utterance on a secondary level text. Data were extracted from Minicorpus DB-IPIC resource FOLK corpus. Linguistic content distribu...

This paper explores how the inand out-domain probabilistic linear discriminant analysis (PLDA) speaker verification behave when enrolment and verification lengths are reduced. Experiment studies have found that when full-length utterance is used for evaluation, in-domain PLDA approach shows more than 28% improvement in EER and DCF values over out-domain PLDA approach and when short utterances a...

This paper deals with F0 declination in Russian. The study was conducted using statistical data derived from the Corpus of Professionally Read Speech. The results confirm the relationship between F0 slope and the utterance length for Russian. At the same time they reveal a) individual strategies in preplanning declination slope of the phrase or utterance; b) strong dependency of the F0 slope on...

We have developed a method to determine whether a user utterance is directed at the system or not. A spoken dialogue system should not respond to audio inputs that are not directed at it (i.e., a user’s mutter), and it therefore needs to detect such inputs to avoid unsuitable responses. We classify the two cases by logistic regression based on a feature set including utterance timing, utterance...
