My thesis aims to contribute towards building autonomous agents that are able to understand their surrounding environment through the use of both audio and visual information. To capture a more complete description of a scene, the fusion of audio and visual information can be advantageous in enhancing the system’s context awareness. The goal of this work is on the characterization of unstructur...

in this study, it was intended to investigate the persian native speakers’ perception of gerunds by three different elicitation techniques i.e., written, audio, and pictorial through translation. eighty intermediate learners of english were asked to select persian translation of the gerund formsin these elicitation techniques. they were asked to choose one option from a pair of written first la...

When designing interaction techniques for mobile devices we must ensure users are able to safely navigate through their physical environment while interacting with their mobile device. Non-speech audio has proven effective at improving interaction on mobile devices by allowing users to maintain visual focus on environmental navigation while presenting information to them via their audio channel...

Environmental audio monitoring is a huge area of interest for biologists all over the world. This is why some audio monitoring system have been proposed in the literature, which can be classified into two different approaches: acquirement and compression of all audio patterns in order to send them as raw data to a main server; or specific recognition systems based on audio patterns. The first a...

Identifying acoustic events from a continuously streaming audio source is of interest for many applications including environmental monitoring for basic research. In this scenario neither different event classes are known nor what distinguishes one class from another. Therefore, an unsupervised feature learning method for exploration of audio data is presented in this paper. It incorporates the...

Rapid increase in the amount of audio data demands an efficient method to automatically segment or classify audio stream based on its content. In this paper, based on the Gabor wavelet features, an audio classification and segmentation method is proposed. This method will first divide an audio stream into clips, each of which contains one-second audio information. Then, each clip is classified ...

Background: Adolescence is one of the most important periods of life for all people. This is a transition period from childhood to adulthood, through which individuals should learn to make the right decisions and apply the life skills.

This study aimed to investigate the effect of pre-teaching new vocabulary items via audio-visuals on Iranian EFL learners’ reading comprehension ability. The question this study tried to answer is if pre-teaching new vocabulary items via audio-visuals have any effect on Iranian EFL learners’ reading comprehension ability. To find the answer to the question, 30 intermediate level stu...
