Which voice in your head is telling the truth?
Modify and reshape your business into an effective, efficient and non-intrusive environment, where operational processes continue without loss of manpower, operational costs and staff friction.
Lior Doron, director of HR Solutions at Nemesysco, recently explained in an article “Explore the future of voice analytics” that “when we speak, we are communicating, expressing and experiencing a range of emotions. All of theses emotions when speaking, whether visible to others or not, cause uncontrolled changes to our voice. These uncontrolled changes contain a wealth of information about our characteristics and intentions.”
For decades employers used the most known ‘Lie Detector Test’ to verify an employee’s truthfulness. A polygraph examiner uses conventional instruments, sometimes referred to as analog instruments, or computerised instruments. A polygraph will collect physiological data from at least three systems in the body, generally over the examinee’s chest and abdominal area, fingers and vascular arm area to record blood pressure. A polygraph examination includes a physical pre-test interview with the examinee, followed by a chart collection phase. During this phase the examiner will ask a set of questions relevant to a specific incident. Following this, the examiner will analyse the charts and render an opinion as to the truthfulness of the examinee.
