Can speech be used for alarm displays in ‘process control’ type tasks?

Baber, C., Stanton, N.A. and Stockley, A. (1992) Can speech be used for alarm displays in ‘process control’ type tasks? Behaviour and Information Technology, 11, (4), pp. 216-226. (doi:10.1080/01449299208924340).

There has been much research into the feasibility of speech in aircraft cockpits, but little in human supervisory control tasks. Speech displays can provide a number of benefits over conventional, visual displays, particularly as a means of providing alarm information. We discuss the term 'alarm', and suggest that different alarm situations will have different information requirements. Thus, a single type of alarm display may not be suitable for the complete range of situations encountered in the control room. We investigated the use of speech for different 'alarm-initiated actions': recording, urgency rating, location identification, and action specification. These tasks varied in terms of difficulty, and this affected performance. We also varied the quality of speech, comparing synthesized with human speech. While speech quality affected performance on the recording task, we found that task difficulty interacted with speech quality on the other tasks. This means that definable 'trade-offs' exist between the use of speech and the situation in which it is to be used.
