摘要：This study describes the methodology used for designing a database of speech under real stress.Based on limits of existing stress databases,we used a communication task via a computer game to collect speech data.To validate the presence of stress,known psychophysiological indicators such as heart rate and electrodermal activity,as well as subjective self-assessment were used.This paper presents the data from first 5 speakers (3 men,2 women) who participated in initial tests of the proposed design.In 4 out of 5 speakers increases in fundamental frequency and intensity of speech were registered.Similarly,in 4 out of 5 speakers heart rate was significantly increased during the task,when compared with reference measurement from before the task.These first results show that proposed design might be appropriate for building a speech under stress database.However,there are still considerations that need to be addressed.
