Telematics is a converging technology to provide users in a car with various services using communication devices and computers such as navigation service, point-of-interest service, email service etc. It is very difficult and dangerous for drivers to input data into a small device and read something while they are on the road. In this paper we suggest a system architecture for developing of vo...

This paper describes a method of generating effective language models for voice query recognition and a new dialogue strategy for a voice activated QA system. By using multiple domain language models, better recognition accuracy is obtained for query utterances. In the proposed interactive dialogue strategy using multimodal user interface, users are requested to indicate correct keywords and in...

Resolution of the fundamental frequency of speech sound required for the design of a speech processor of a cochlear implant device is investigated, with special regard to transmitting voice pitch information in Asian languages. Clinical application of the cochlear implant has spread rapidly in recent years to Asian countries where a variety of languages having different voice pitch information ...

The paper describes two input devices and a software interface that allow severely impaired people to easily interact with a personal computer. The first input device does not require residual movement but makes use of skin electrical signals and applies Artificial Neural Networks to decode the mind-driven commands. The second input device is an evolution of a proximity sensor that can be activ...

The visually-impaired segment of the population, the inability to read has a substantive negative impact on their quality of life. Printed text (books, magazines, menus, labels, etc.) still represents a sizable portion of the information this group needs to have unrestricted access. Over the years speech recognition has taken the market. The speech input can be used in varying domains such as a...

This paper describes the development of a voice-input voice-output communication aid (VIVOCA) for people with disordered or unintelligible speech, initially concentrating on people with severe dysarthria. The VIVOCA is intended to recognize and interpret an individual’s disordered speech and speak out an equivalent message in clear synthesized speech. User consultation suggests that such a devi...

Spoken word recognition is characterized by multiple activation of sound patterns that are consistent with the acoustic-phonetic input. Recently, an extreme form of multiple activation was observed: Bilingual listeners activated words from both languages that were consistent with the input. We explored the degree to which bilingual multiple activation may be constrained by fine-grained acoustic...

Programming is an activity centred primarily around the keyboard which is not necessarily the optimal input device for all users. Little research has taken place into alternative input devices for programming despite huge advances in handwriting and voice recognition for natural language. This project explored using a pen as the primary input device for programming. A variety of different metho...

In this study, six patients who were judged to produce speech with excessive laryngeal tension participated in 14 30-min biofeedback training sessions. The EMG signal, measured by bipolar surface electrodes placed over the cricothyroid region, was amplified, integrated, and used to control the output of a voltage controlled oscillator (VCO) and a noise generator. A voltage comparator was used a...
