In this paper, we presented a semantic speech segmentation approach, in particular sentence segmentation, without speech recognition. In order to get phoneme level information without word recognition information, a novel vowel/consonant/pause (V/C/P) classification is proposed. An adaptive pause detection method is also presented to adapt to various background and environment. Three feature se...

Increasing interest in multimedia research has been drawn upon the development of video indexing and content-based image retrieval techniques. In this report, we proposed several pause detection algorithms, which instead of searching for signi cant visual transitions, the algorithms detect signi cant pauses in video streams. A realization of the algorithmswas implemented using ImageTcl toolkit ...

This paper presents two new algorithms for robust speech pause detection (SPD) in noise. Our approach was to formulate SPD into a statistical decision theory problem for the optimal detection of noise-only segments, using the framework of model-based speech enhancement (MBSE). The advantages of this approach are that it performs well in high noise conditions, all necessary information is availa...

This study investigated how acoustic cues signal the different syntactic structures of ambiguous sentences in language production. Acoustic cues such as intensity, f0, pause and duration vary according to different syntactic boundaries. Intensity of post-boundary syllable, f0 reset range of syllables around the corresponding target boundary, pause, and final lengthening of preboundary syllable ...

We investigate how to add rate control to full-duplex IEEE 802.3 Ethernet. We envision the need for rate control in order to enable bandwidth allocation in future Ethernet in the First Mile (EFM) subscriber services. We propose a RATE mechanism that can be implemented with a simple byte-based leaky bucket. We demonstrate with simulation methods that RATE can isolate flows and provide lower loss...

Pauses in spontaneous speech have a less restricted distribution than pauses in read discourse; however, they are not distributed in a haphazard way. The majority of the perceived pauses in the examined Swedish spontaneous speech material, 73%, occurred in one of the following positions: between sentences, after discourse markers and conjunctions, and before accented content words. There is a r...

In comparing open and closed economies, researchers often arrange shorter sessions under the former condition than under the latter. Several studies indicate that session length per se can affect performance and there are some data that indicate that this variable can influence demand functions. To provide further data, the present study exposed domestic hens to series of increasing fixed-ratio...

The present research addressed the prosodic realization of global and local text structure and content in the spoken discourse data produced by Persian EFL learners. Two newspaper articles were analyzed using Rhetorical Structure Theory. Based on these analyses, the global structure in terms of hierarchical level, the local structure in terms of the relative importance of text segments and the ...

The suffix ''–some'' is derived from the Greek word ''soma,'' which means body. Molecular biologists use the ''–some'' suffix when naming macromolecular assemblies, such as the ribosome, spliceosome, and exosome, and more recently the metabolosome and periodosome. This issue's Molecular Biology Select discusses reports that highlight the functional and structural intricacies of these systems. R...
