Voice Analysis vs. Graphology: The tool of choice for your pre-employment selection and screening needs

By Dr. Albert de Vries

When a company sets out to hire new managerial personnel, they deserve something better than a guessing board game. When you opt for graphology as your tool of choice, that is basically what you get. Nemesysco's new HR1 system uses advanced voice analysis technology to provide a complete report of your prospective employee in terms of overall veracity, integrity, and credibility. HR1 is a scientifically reliable credibility assessment tool based on the Layered Voice Analysis (LVA) technology.

Among the most important questions for a prospective employer are whether the various facts, accomplishments, and credentials that appear on a job applicant’s CV or resume are true and accurate. These are questions that a graphology examination cannot answer. Voice analysis, on the other hand, can and does so in a reliable manner. Using cognitive interviewing techniques, a CV or resume can be reviewed with the applicant either via telephone or during a face-to-face interview. The truth becomes immediately apparent in the interview process. This form of examination provides the employer with a veracity analysis, in addition to an overall credibility assessment. Questions concerning the applicant’s education, former places of employment, achievements, and goals can be asked. Responses in each of these areas are then scored for their truthfulness as well as their emotional “content” and accompanying stress. Voice, like handwriting, is a manifestation of cerebral activity. When an individual knows he or she is being deceitful, and is to any degree uncomfortable with it, the result is a form of cognitive stress that is reflected in the voice. Because these vocal changes are minute and often inaudible, the individual cannot easily identify or control them. Finely tuned voice analysis, however, can identify and analyze these changes. This information, together with an overall credibility assessment score, are included in the final report delivered to the employer.

What else does an employer or search firm need to consider when selecting a screening tool?

The cost factor: In most cases, an applicant voice analysis costs 50% less than a graphology work-up.
The expedience factor: Voice analysis reports are sent within 24 hours of receipt of the raw data.
The level of accuracy: Voice analysis (LVA) focuses on those areas that are ranked as most important to the employer with accuracy rates of 90% and higher.
Personality profiles are important and employers want to know what makes their applicant “tick”. Here both graphology and voice analysis provide answers. However, voice analysis monitors thinking patterns, coping capabilities, and stress reactions in real-time.

So why do so many companies still rely on graphology when making a decision to hire an executive or manager? Two reasons are; a) tradition, and b) lack of awareness that there are newer, more effective pre-employment screening and selection tools available. Graphology has been used for many years in the pre-employment selection process due to its non-invasive character and its image of being less threatening to job seekers than, for example, the polygraph. While this is probably true, the LVA process is not only non-invasive, it is also markedly less threatening because the applicant is completely unaware that the process is taking place. Unfortunately, voice analysis has been overlooked because it is a relative newcomer in the field of screening, selection and credibility assessment. However, the benefits and usage potential of this advanced technology are revolutionizing the field.

There is no doubt that when one considers the cost of executive /manager training, hiring mistakes can be highly consequential. Incorporating LVA technology into your selection procedure will reduce the number of false-positive errors, and increase assessment accuracy significantly.

The scientific basis for the accuracy of a voice analysis protocol has been established via a series of studies and trials conducted in a number of countries around the world. The results of voice analysis (LVA) in on-line mode are over 90% accurate, and slightly higher when using the in-depth off-line mode. References and research articles relating to these studies are available upon request.

Layered Voice Analysis (LVA) is currently the only voice analysis technology that is commercially used for credibility assessment, identifying emotions, analyzing an applicant’s thought processes, and generating automated veracity assessments. All of the voice analysts and researchers working on LVA technology at Nemesysco's headquarters are formally trained professionals with backgrounds in psychology, law enforcement, polygraph examinations, and private investigative work.

Choose the most effective tools and methods for screening and selecting your prospective employees. Among the critical factors are accuracy, expediency, and cost effectiveness of the tool. Consider the options available in the field, and explore how advanced voice analysis can help meet your organizations needs for making important HR decisions.
