This article is based on the research the author undertook in order to develop my doctoral thesis – The organicity of speaking disorders in theatre and film, a defining statement in the construction of the characters. The purpose of my entire work, entitled, the organicity of speaking disorders in theatre and film, a defining statement in the construction of the characters, was to perform a series of vocal training exercises that would lead to the natural use by actors of a speech defect. Therefore, verbal language is very important for an actor; it is part of the whole mechanism of the actor’s art. If it does not work perfectly, the other elements will suffer as well. But what is the connection between speech and personality? Does speech influence our personality or does personality influence our speech? The author thinks that both variants can be valid for the study of a character. If the text gives us information about the way a character speaks, if he is stuttering, e.g., we can start the analysis from this aspect. Or if, after reading, we consider that a character falls into a certain category of temperament / personality, the based on these data, we can build his verbal behaviour.
