this study was an attempt to explore the role that the increased perceptual saliency of l2 input features or output flaws and hereby promoting l2 learners’ noticing (through planned instructional activities) can play in the learners’ use of correct english intonation patterns. the participants were 80 iranian efl students attending four intact classes, two low-intermediate and two upper-interme...

Infant and adult learners are able to identify word boundaries in fluent speech using statistical information. Similarly, learners are able to use statistical information to identify word-object associations. Successful language learning requires both feats. In this series of experiments, we presented adults and infants with audio-visual input from which it was possible to identify both word bo...

To evaluate the effect of the tidal cycle on the pore water nitrate dynamics in intertidal sediment, concentrations of inorganic nitrogen in water and sediment were monitored during tidal cycles in the mud flat of Tama Estuary, Japan. During submergence, nitrate concentration was highest in the overlying water and decreased monotonically with increasing depth in the sediment, suggesting that th...

This paper describes audio-visual speech recognition experiments on a multi-speaker, large vocabulary corpus using the Janus speech recognition toolkit. We describe a complete audio-visual speech recognition system and present experiments on this corpus. By using visual cues as additional input to the speech recognizer, we observed good improvements, both on clean and noisy speech in our experi...

We propose a person identi cation technique that can recognize and verify people from unconstrained video and audio. We do not expect fully frontal face image or clean speech as our input. Our recognition algorithm can detect and compensate for pose variation and changes in the auditory background and also select the most reliable video frame and audio clip to use for recognition. We also use 3...

Spiking cochlea models describe the analog processing and spike generation process within the biological cochlea. Reconstructing the audio input from the artificial cochlea spikes is therefore useful for understanding the fidelity of the information preserved in the spikes. The reconstruction process is challenging particularly for spikes from the mixed signal (analog/digital) integrated circui...

Direct manipulation, which is the dominating “interaction style” for mobile computers, fails to meet the conditions of many mobile use situations. In particular, it demands too much visual attention of the user. We introduce a new, complementing interaction style (and system) for mobile computers, called MOTILE, which addresses three main requirements of interaction with mobile computers: (1) n...

A stereophonic enhancement system is described which expands the perceived width of the stereo sound image. The system accepts electrical audio signals comprising a two-channel (left and right) stereo pair and produces enhanced left and right stereo signals for use with conventional two-channel audio recording and playback systems. The system includes control circuitry which monitors the dissim...

An audio band sigma-delta ADC based on a new time-interleaved !! scheme is described. The circuit achieves a very low power operation with the large dynamic range required for audio applications. This modified two channel timeinterleaved scheme improves the power efficiency thanks to halved operating frequency in the paths, and a reduced number of levels in ADC and DAC. This sigma-delta modulat...
