We describe the use of non-verbal features in voice for direct control of interactive applications. Traditional speech recognition interfaces are based on an indirect, conversational model. First the user gives a direction and then the system performs certain operation. Our goal is to achieve more direct, immediate interaction like using a button or joystick by using lower-level features of voi...

Establishing voice circuits by transmitting voice packets, i.e., transmitting only when there is sound, has been studied for some 30 years. Despite the theoretical efficiency few such systems have been implemented, possibly because of the inadequacy of available multiple access protocols. A new protocol, DQRAP (Distributed Queueing Random Access Protocol), developed by Xu and Campbell at the Il...

We examine relationships among Internet diffusion, voice and accountability, and government corruption based on data from 24 Latin American and 23 sub-Saharan African countries from 2006 to 2010. Our study suggests that greater levels of Internet diffusion are associated with greater levels of voice and accountability and that greater levels of voice and accountability are associated with lower...

Abstmet-This paper addresses the static and centralized routing of voice and data traffic in burst switched networks. Since voice and data have markedly different traffic characteristics and performance requirements , their interaction in a unified switching and transmission structure greatly impacts their performance. Voice performance in a burst switched network is primarily measured by end-t...

Background: Although voice tremor is one of the most commonly noted clinical features of essential tremor (ET), there are nearly no published data on the handicap associated with it. Methods: The Voice Handicap Index (VHI) was self-administered by participants enrolled in a research study at Columbia University Medical Center. The VHI quantifies patients’ perceptions of handicap due to voice di...

objectives: nasality is one of the important parameters in pathology of voice resonance. voice of normal adults has nasality to some extent. it appears that nasality, like other parameters of voice, can be affected by loudness which can be measured in experimental evaluations. this study was conducted to determine the effect of vocal loudness on nasalance of vowels in normal adults and to ident...

The application of speech recognition (SR) in aviation is rapidly evolving and moving toward more common use on future flightdecks. The concept of using SR in aviation is not new. The use of speech recognition and voice control (VC) has been researched for more than 20 years, and many of the proposed benefits have been demonstrated in varied applications. Continuing advances in computer hardwar...

This report summarizes key results of an on-road study assessing perceived workload, physiological arousal, visual attention, and basic driving performance metrics while drivers engaged in a number of tasks with a production version, in-vehicle voice-command system. The same metrics were also evaluated while participants carried out an implementation of the manual radio tuning reference task (D...

This paper considers the interaction between a proposed data access control scheme and the standardized error recovery schemes on the radio link of a voice/data CDMA system. A data access control scheme for combined voice-data CDMA systems has been proposed and studied in previous literature. The scheme aims to maintain a certain target voice SIR; this is achieved by controlling the data load a...

mannion and davies’ article recognises whistleblowing as an important means of identifying quality and safety issues in healthcare organisations. while ‘voice’ is a useful lens through which to examine whistleblowing, it also obscures a shifting pattern of uncertain ‘truths.’ by contextualising cultures which support or impede whislteblowing at an organisational level, two issues are overlooked...
