Hapeshi, Kevin and Jones, Dylan (1992): Interactive Multimedia for Instruction: A Cognitive Analysis of the Role of Audition and Vision. In International Journal of Human-Computer Interaction, 4 (1) pp. 79-99.

“Interactive multimedia provide a platform for delivering instructional material in different modalities and styles. Experimental work on learning and memory is extensive, particularly for verbal learning. However, little attention has been paid to the relative effectiveness of auditory and visual presentation. We warn against simply transferring techniques developed in more traditional audiovisual systems, arguing instead for an approach based on experimental analysis. In this article we review studies that suggest a series of tentative guidelines on the use of auditory and visual presentation in multimedia learning systems. These guidelines are intended as an aid to both programme developers and users, but they also serve to highlight areas requiring further research.”

Frankish, Clive, Jones, Dylan and Hapeshi, Kevin (1992): Decline in Accuracy of Automatic Speech Recognition as Function of Time on Task: Fatigue or Voice Drift?. In International Journal of Man-Machine Studies, 36 (6) pp. 797-816.

“Recognition accuracy of speech recognition devices tends to decline during an extended period of continuous use. Although this deterioration in performance is commonly acknowledged, there has been little systematic observation of the phenomenon, and no clear account of its causes is available. The aim of this present study was to provide some indication of the magnitude and time course of this decline in performance, and to clarify the nature of underlying changes in speech behaviour. Three experiments are described. Experiment 1 confirmed that there is a fall-off in recognition accuracy during a half-hour session of a data entry task, and that this occurs for both naive and practised subjects. In Experiment 2, no recovery was observed in recognition performance when short rest breaks were scheduled, indicating that vocal fatigue was not a major factor. The effects of template retraining in mid-session were investigated in Experiment 3. This procedure was found to be effective in restoring recognition accuracy, and the retrained templates were relatively robust. The implications of these findings for operational use of speech recognition devices are briefly discussed. For most application, one-off template retraining is seen as a more appropriate solution to the problem of voice drift than more complex solutions based on adaptive templates.”

Jones, Dylan (1989): The Sonic Interface. In: Proceedings of the Third International Conference on Human-Computer Interaction 1989. pp. 382-388.

“Interfaces which use sound, employing speech input, speech output or non-speech sounds, are the subject of much advocacy. This paper undertakes a critical evaluation of such interfaces, using a functional analysis of the human uses of speech as a starting point. Sound, it is argued, is attention grabbing, public, transient, related to attributes not objects, and induces anthropomorphism. The effect of each of these qualities is to suggest only a limited range of settings in which sonic interfaces are useful.”

Jones, Dylan, Hapeshi, Kevin and Frankish, Clive (1987): Human Factors and the Problems of Evaluation in the Design of Speech Systems Interfaces. In: Diaper, Dan and Winder, Russel (eds.) Proceedings of the Third Conference of the British Computer Society Human Computer Interaction Specialist Group - People and Computers III August 7-11, 1987, University of Exeter, UK. pp. 41-49.

“As part of a project in the Alvey programme, during the next two years we will be carrying out experimental studies aimed at generating human factors guidelines for the design of automatic speech recognition systems for avionics and office applications. The planning of the programme of experimental work has thrown up some unique and interesting methodological issues. Firstly, there are a range of factors which can affect performance in the speech recognition system. Secondly, the choice of dependent variable is not easy, since there are a number of possible 'yardsticks' by which recognition performance can be assessed, none of which are, on their own, entirely satisfactory. In this paper we describe these methodological problems and suggest some possible solutions.”
