Vox Performance® Vox - a computerised Voice Audit

The human voice is a powerful tool for persuasion and leadership. It is very complex, it encodes the speaker's personality, attitudes, style and emotions.

We all find it easy to detect when someone is sad, angry, interested or bored by listening to the inflection and timbre of their voice. However, analysing the way an individual uses his voice is a difficult task and it is often entirely subjective.

We have turned this subjective approach into a wholly objective one. Thanks to dedicated software, we are now able to analyse a human voice and detect with precision its acoustic features.

Voice Analysis

Several samples of the client's voice are digitally recorded. These are analysed using acoustic signal analysis software and the results are then compared with those of a reference 'model' speaker's voice. The reference values were compiled by analysing a large number of highly effective communicators. The acoustic analysis produces a voice profile as shown in the octagon below. Different points represent the percentages of the model speakers’ values.

Armed with the objective facts one can then work on specific aspects in order to communicate more effectively. Such a Voice Audit provides precise objectives for professional training in delivery skills.

Image Analysis

The hexagon below is an example of the resulting image analysis of a speaker. As one can see, this person obtains high scores on pleasantness and clarity but does poorly on dynamism and persuasiveness.
