Effective haptic feedback in virtual reality (VR) is an essential element for creating convincing immersive experiences. To design such feedback, state-of-the-art VR setups provide APIs for programmatically generating controller vibration patterns. While tools for designing vibrotactile feedback keep evolving, they often require expert knowledge...

This paper examines if the voicing of a consonant, in Ika, has any influence on the acoustic features of a preceding vowel. Ika (ISO 639-3 ikk) has nine vowels and this work centres on them. Nine pairs of words beginning with Ika vowels (the vowels preceding either voiced or voiceless consonants) were produced and analysed using the praat speech...

Bandwidth is still a limiting factor for the Quality of Service (QoS) of mobile communication applications. In particular, for Voice over IP the QoS is not yet as good as for common, well-engineered, public-switched telephone networks. Multisensory communication has been identified as a possibility to moderate this limitation. One of the...

Introduction: Inner voice is estimated to occur at least a quarter of people’s conscious waking life. Much research work asserts that inner voice plays various important roles in cognitive functions, such as self-regulation, self-reflection, and so on. Virtual cognitions are a stream of simulated thoughts people can hear while emerged in a...

A number of negotiation training systems have been developed to improve people’s performance in negotiation. They mainly focus on the skills development, and less on negotiation understanding and improving self-efficacy. We propose a virtual reality negotiation training system that exposes users to virtual cognitions during negotiation with...

Entrepreneurs with the ambition to structurally cater the Base of the Pyramid (BoP) market face two challenges. On the one hand, they need to ‘go local’ to ensure local ownership. On the other hand, they have to work towards a scalable business model. This paper presents a framework which combines the innovation phases with the challenges of...

One of the most important simulation assets is the data that is collected during executions. Imagine being able to look back, analyze and reuse the data of simulations that have been run during the last decade. However, data logging has a number of challenges, not the least in today’s environment where we need to train jointly and combined and...

The extent to which the modeling used in objective speech quality algorithms depends on the cultural background of listeners as well as on the language characteristics using American English and Igbo, an African tone language is investigated. Two different approaches were used in order to separate behavioral aspects from speech signal aspects....

The Generic Methodology for Verification and Validation (GM-VV) is a generic methodology for VV&A to justify the acceptability of models, simulation, underlying data and results for an intended use. This methodology is currently in the processes of standardization within the SISO. The GM-VV attains its genericness from a framework approach,...

Quality of Service (QoS) support in the current internet is indispensable because of QoS-sensitive real-time applications such as Voice-over-IP, IP-TV, video conferencing, online gaming etc. Since the introduction of the Differentiated Services (Diff-Serv) architecture there has been considerable work reported in literature on its performance...

An experiment was conducted to investigate the effects of accent, telephone and a relatively long retention interval (3 or 8 weeks) on speaker identification. Three-hundred and sixty participants heard the target's voice and were asked to identify the target by means of a line-up consisting of 6 voices. Half of the participants were given a...

A short-term and potentially cost-effective solution is proposed for tactical radio communications in Military Operations in Urban Terrain (MOUT) for the Royal Netherlands Army (RNLA). Measurements and computer simulations presented show that on average, outdoor ranges in MOUT as attainable with RNLA's current VHF (Very High Frequency) Combat...

An experiment was conducted to investigate the reliability of voice lineups. More specifically, the experiment was designed to look into the effects of retention interval (an immediate test or after a week), speech duration (30 or 70 s) and acoustic environment (indoors or indoors and outdoors) on speaker identification accuracy. In addition,...

This contribution deals with the estimation of the relation between speech transmission quality and average call duration for a given network and portfolio of customers. It uses non-intrusive speech quality measurements on live speech calls. The basic idea behind this analysis is an expectation that the average call duration is higher for calls...
