Background:
The stomatognathic system is a morphological and functional complex of tissues and organs involved in the functions of chewing, breathing, expressing emotions and articulating sounds. Speech is one of the functions of this system.

Aim:
Comparison of the graphical movement of the condyles in an axiographic examination in people reporting a subjective voice handicap.

Material and methods:
Generally healthy patients were enrolled in the study. The patients were qualified using the results of a questionnaire in which the patients provided answers to questions regarding the self-assessment of their speech. All patients underwent an axiographic examination in which the movements of the condyles during speech were recorded.

Results:
There was obtained an average score of 8 points for the control group and 36 points for the study group in VHI. The analysis of speech graphs showed symmetrical movement of more than 1 mm in 7 patients from the control and in 1 patient from the study group. Symmetric movement with a range of more than 1 mm was recorded in 8 patients from the control and in 1 patient from the study group. Asymmetric movement was observed group in the 4 patients of the study group.

Conclusions:
The use of the VHI is a tool which can be used to refer patient for extended diagnostics. The axiographic examination allows for an objective assessment of the activity of the condylar processes during speech. Preliminary results of the conducted study indicate a trend of more frequent occurrence of asymmetry during speech in patients with subjective speech disability.
