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.

The Backstory

It was originally invented in Israel in 1997, for security purposes, but today it has expanded into the public market too, and is currently on its 7th generation.

Layered Voice Analytics technology identifies various types of stress levels, cognitive processes, and emotional reactions that are reflected in different subtle properties of the voice. This information provides insights into the way employees think, what troubles them, what excites them, what portions of the respondents speech is uncertain, it highlights those questions that require more attention, as well as highlighting those areas that appear to be sensitive issues for the employee.

LVA uses a unique mathematical process to detect different types of patterns and anomalies in the speech flow, and then classifies them in terms of stress, excitement, confusion and other relevant emotional states.

Diverse Industries

Since the initial lockdown period in April 2020, XTND has assisted several heavy haulage and courier companies to instantly transform their risk mitigation process to an automated, effective and efficient process. It is well known that transport companies rely heavily on polygraph examinations for pre-employment as well as screening methods.

5 incidences when an employer is entitled to use polygraph testing

  • employees have had access to the employer’s property that is subject to an investigation;
  • the employer has suffered some sort of economic loss such as theft of company property;
  • there is suspicion that an employee was involved in such an incident;
  • the employer is trying to deal with dishonesty of employees who occupy positions of trust; and
  • for purposes of investigating syndicate or fraudulent behaviour in the workplace.

According to the Vollmer Institute, 28 November 2018 “Most polygraph tests take between 1 and 2 hours, but the examinee is attached to the device for only 15 to 20 minutes.”

Businesses need to not only remain competitive, but need to manage criminal activity too. Businesses that reshape and modify their environment into an effective, efficient and non-intrusive environment, are better positioned to stay ahead if their environment allows operational processes to continue without the associated negative loss of manpower, operational costs and staff friction.
