This exercise requires more than one participant.

• Select the physical and expressive features (outer characteristics) and the interests and traits (Inner Characteristics) you want to examine.
• Select a number of voices that you want to examine.
• Try individually to fill out the form - just from the impression of the speaker.
• After: Compare answers. If there are elements you strongly disagree on you might have to change the category.

If you want to do a larger study on voice and perceptive assessment you will have to make a manual where you 1) describe every category 2) test on minimum two other persons how they assess the similar voices.
