Language Identification (LID) systems are used to classify the spoken language from a given audio sample and are typically the first step for many spoken language processing tasks, such as Automatic Speech Recognition (ASR) systems. Without automatic language detection, speech utterances cannot be parsed correctly and grammar rules cannot be applied, causing subsequent speech recognition steps ...

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...

Three-dimensional (or spatial) audio is a growing research field that plays a key role in realizing immersive communication in many of today’s applications for teleconferencing, entertainment, gaming, navigation guidance, and virtual reality (VR)/augmented reality (AR). Technologies in spatial sound capture and binaural recording are becoming an add-on module to our mobile devices to capture th...

 WiFi is a common communication interface for smart devices.  WiFi still has some perturbation such as: – Poor utilization of wireless channel. – Energy consumption during idle state. – Unfairness issue due to capture effect.

Recently, automatic speech recognition (ASR) and visual (VSR) have been widely researched owing to the development in deep learning. Most VSR research works focus only on frontal face images. However, assuming real scenes, it is obvious that a system should correctly recognize spoken contents from not but also diagonal or profile faces. In this paper, we propose novel method applicable faces ta...

In this study, we consider the propagation of the Love-type wave in piezoelectric gradient covering layer on an elastic half-space having an imperfect interface between them. Dispersion relation has been obtained in the form of determinant for both electrically open and short cases. The effects of different material gradient coefficients of functionally graded piezoelectric material (FGPM) and ...

The current generation of mobile devices is capable of producing polyphonic sounds, has enough processing power for real-time signal processing, and much better sound quality than their predecessors. The importance of audio is increasing as we are moving towards multimodal user interfaces where audio is one of the major components. In this paper, we present new ways of using audio feedback more...

Digital Audio Broadcasting (DAB) is an emerging technology which is currently experiencing rapid growth following the advent of ETS 300-401 DAB standard in Europe and the ATSC ATV standard in the U.S. Wide-band audio compression is performed by ISO-MPEG layer II for DAB, and by Dolby AC-3 for ATV. To achieve high quality audio, current DSP implementations for such compression algorithms typical...
