Today, a large number of audio features exists in audio retrieval for different purposes, such as automatic speech recognition, music information retrieval, audio segmentation, and environmental sound retrieval. The goal of this paper is to review latest research in the context of audio feature extraction and to give an application-independent overview of the most important existing techniques....

Unstructured audio is an important aspect in building systems that are capable of understanding their surrounding environment through the use of audio and other modalities of information, i.e. visual, sonar, global positioning, etc. Consider, for example, applications in robotic navigation, assistive robotics, and other mobile device-based services, where context aware processing is often desir...

Vision and touch are essential sensory systems for human to interact with the environment. For blind amputees, how quickly intuitively convey environmental information them is one of key issues recovering their daily living ability. Inspired by auditory localization ability human, we constructed a virtual scene almost identical reality, concurrently added sound source interactive object. Levera...

Vocabulary is an important component of language proficiency which provides the basis for learners’ performance in other skills. But, since vocabulary learning seems to be so demanding, learners tend to forget newly-learnt words quite soon. In order to identify vocabulary learning conditions which can produce a more lasting effect, this study investigated the effect of three kinds of gloss cond...

this paper presents a new audio encryption algorithm based on permutation and residue number system. in the current approach, signal samples are combined with residue number system through permutation; therefore, a specific noise is generated. then, the audio signal is combined with the noise, generated by the algorithm, to produce a silence signal. for this purpose, the algorithm uses a predef...

Ambient Assisted Living (AAL) has become an attractive research topic due to growing interest in remote monitoring of older people. Development in sensor technologies and advances in wireless communications allows to remotely offer smart assistance and monitor those people at their own home, increasing their quality of life. In this context, Wireless Acoustic Sensor Networks (WASN) provide a su...

Audio editing is performed at scale in the production of radio, but often the tools used are poorly targeted towards the task at hand. There are a number of audio analysis techniques that have the potential to aid radio producers, but without a detailed understanding of their process and requirements, it can be difficult to apply these methods. To aid this understanding, a study of radio produc...
