Design Considerations for Improving the Effectiveness of Multitalker Speech Displays

چکیده
Although many researchers have commented on the potential of audio display technology to improve intelligibility in multitalker speech communication tasks, no consensus has been reached on how to design an “optimal” multitalker speech display. This paper reviews a set of experiments that used a consistent procedure to evaluate the impact of six different parameters on overall intelligibility in multitalker speech displays: 1) the signal-to-noise ratio; 2) the number of competing talkers; 3) the voice characteristics of the talkers; 4) the relative levels of the talkers; 5) the apparent locations of the talkers; and 6) the listener’s a priori information about the listening task. The results are discussed in terms of their implications in the design of more effective multitalker speech displays.

Improving Multitalker Speech Communication with Advanced Audio Displays
Historically, most of the metrics that have been used to evaluate the effectiveness of military communications systems have focused on measuring the intelligibility of a single talker in the presence of a continuous noise masker. However, many critical military operations involve complex communications tasks that require listeners to monitor, process, and respond to two or more simultaneous spe...

Although many researchers have commented on the potential of audio display technology to improve intelligibility in multitalker speech communication tasks, no consensus exists on how to design an “optimal” multitalker speech display. In this article, we review several experiments that have used a consistent procedure to evaluate the effect of four monaural parameters on overall intelligibility....

The aim of this paper is to report on an attempt to design and implement an intelligent system capable of generating the correct part of speech for a given sentence while the sentence is totally new to the system and not stored in any database available to the system. It follows the same steps a normal individual does to provide the correct parts of speech using a natural language processor. It...

For decades, single case experimental designs (SCED) have been used to examine the effectiveness of clinical and educational interventions and have contributed significantly to the development of the general lines of clinical and educational researches. In recent years, with the movement of evidence-based methods, the methodology of single case experimental designs has also evolved. Visual anal...
متن کاملSpatial and temporal modifications of multitalker speech can improve speech perception in older adults.
Speech perception in multitalker environments often requires listeners to divide attention among several concurrent talkers before focusing on one talker with pertinent information. Such attentionally demanding tasks are particularly difficult for older adults due both to age-related hearing loss (presbacusis) and general declines in attentional processing and associated cognitive abilities. Th...
