A voice-based stress detector has been developed in Australia to assist in spotting out job candidates who will be successful even under pressure.
Bo Yin at National Information and Communications Technology Australia, in Sydney, said that normally we have full control over our vocal muscles and change their position to create different intonations, reports New Scientist.
Advertisement"But when stressed, we lose control of the position of the speech muscles," and our speech becomes more monotone, he added.
Yin tested his stress detector in a call centre to identify which interviewees were more relaxed during recruitment tests.
The number of new staff that left after three months subsequently fell from 18 per cent to 12 per cent, he claimed.
The detector was shown at trade show CeBIT Australia in May.
