Background: eHealth services can contribute to individuals’ self-management, that is, performing lifestyle-related activities and decision making, to maintain a good health, or to mitigate the effect of an (chronic) illness on their health. But how effective are these services? Conducting a randomized controlled trial (RCT) is the golden...

The "Toets Gesproken Nederlands" (TGN) is developed to test the oral language proficiency level in Dutch. The TGN tests whether a candidate possess a certain minimum proficiency level by scoring the answer to short questions with an automatic speech recognition system. In 2007, TNO performed a study to tests whether the differences exist between...

The scope of 3D geo information applications is broadening to include for instance crises management and training. These new applications are no longer restricted to expert users, but aimed at involving a multitude of (non-professional) stakeholders in a participatory design and decision process. This introduces new challenges for the user...

Objective: The aim of the current study was to examine whether partly incorrect subtitles that are automatically generated by an Automatic Speech Recognition (ASR) system, improve speech comprehension by listeners with hearing impairment. In an earlier study (Zekveld et al. 2008), we showed that speech comprehension in noise by young listeners...

This paper presents a methodology to apply speech technology for compensating sensory, motor, cognitive and affective usage difficulties. It distinguishes (1) an analysis of accessibility and technological issues for the identification of context-dependent user needs and corresponding opportunities to include speech in multimodal user interfaces...

This study examined the subjective benefit obtained from automatically generated captions during telephone-speech comprehension in the presence of babble noise. Short stories were presented by telephone either with or without captions that were generated offline by an automatic speech recognition (ASR) system. To simulate online ASR, the word...

In this paper, both categorical and dimensional annotations have been made of neutral and emotional speech synthesis (anger, fear, sad, happy and relaxed). With various prosodic emotion manipulation techniques we found emotion classification rates of 40%, which is significantly above chance level (17%). The classification rates are higher for...

OBJECTIVES: The aim of this study was to evaluate the benefit that listeners obtain from visually presented output from an automatic speech recognition (ASR) system during listening to speech in noise. DESIGN: Auditory-alone and audiovisual speech reception thresholds (SRTs) were measured. The SRT is defined as the speech-to-noise ratio at which...

In this paper, we describe N-best 2008, the first Large Vocabulary Speech Recognition (LVCSR) benchmark evaluation held for the Dutch language. Both the accent as spoken in the Netherlands (Northern-Dutch) and in Belgium (Southern-Dutch or Flemish), will be evaluated. The evaluation tasks are broadcast news (BN) and conversational telephone...
