During the feature extraction phase, several methods have been used, such as voice activity detection (VAD), mel-frequency cepstral coefficients, perceptual linear prediction, relative perceptual linear prediction, and their first-order time derivatives. The main problems of recognition of Kazakh speech, VAD algorithms and speech segmentation, lip movement recognition are considered in the article. The description of probabilistic modelling of audiovisual speech based on coupled hidden Markov models (HMMs), information fusion methods with weight coefficients for audio and video speech modalities, and parametric representation of signals is provided. Quantitative results in multimodal recognition of continuous Kazakh speech indicate high accuracy and reliability of the automatic system. This approach has been used and compared in terms of computational time and recognition speed and gives very interesting results.","PeriodicalId":433337,"journal":{"name":"Int. J. Mob.

The positive impact of VR on news attitudes was mediated by presence and subsequent enjoyment.","PeriodicalId":433337,"journal":{"name":"Int. J. Mob.

Taking the opportunity offered by the recent launch of Apple Pay in China, this research aims to investigate the determinants of the behavioural intention to adopt NFC-enabled mobile payment services. The proposed model extends the technology acceptance model (TAM) with consumer trust, service quality dimensions and prior experience of users. The model is tested using survey collected from 166 iPhone users in China. Perceived usefulness and trust are identified as significant drivers of behavioural intention to use Apple Pay. Among all the service quality dimensions, reliability is identified the most important factor affecting behavioural intention through perceived usefulness, which reflects consumers' emphasis for stable, error-free transaction experience. Structural assurances, calculative-based trust and confidentiality are also shown to have indirect positive influence on behavioural intention through paths on trust. Finally, the mediation effects of perceived usefulness and perceived ease of use are analysed.","PeriodicalId":433337,"journal":{"name":"Int. J. Mob.

This paper provides a comparative study for web application protection techniques and evaluates their performance against SQLIA by conducting a detailed review of various SQLIA previously detected and prevented by protection techniques, a summary and analysis of a critical review of the defensive techniques that were done to address such attack, performance comparison of the different protective approaches through an evaluation using performance metrics to identify efficient and high-performance techniques. Finally, the paper highlights and focuses on the critical and vital directions or protection approaches that require more studies by future research.","PeriodicalId":433337,"journal":{"name":"Int. J.

To investigate success factors of smart devices, we conducted two survey studies regarding cell phones, tablet computers, and laptop computers.

Finally, we compared these two results and finalised the success factors for smart devices, which include the following. People want to repurchase innovative smart devices with good design. Products with competitive advantage and good usability that meet customer needs are recommended by individuals who have used them.

We identified 14 highly influential articles in the evolution of MB literature. We found that the majority of the articles were written in an Asian context. The predominant theme shifted from MB adoption to the impact of MB on the effectiveness of individual lives. The primary concern of MB users changed from risk to usefulness, especially among the young users. The implications for financial institutions include focusing on consumer lifestyle, monitoring security measure and communicating to college students as the main potential customers.","PeriodicalId":433337,"journal":{"name":"Int.

The results show that two contrasting mechanisms, dedication-based and constraint-based relationships, simultaneously determine customer resistance to churn. The constraints of procedural, financial, and relational costs significantly influence perceived risk, while dedication factors of economy-based and identification-based trust significantly influence commitment.","PeriodicalId":433337,"journal":{"name":"Int.
