This master’s thesis project examines the possibilities of visualizing non-verbal aspects of spoken language in written and printed form. The opening part deals with chosen semiotic and linguistic theories and their relationship to spoken and written language. Afterwards practical examples from the field of concrete poetry and word-sound compositions are analyzed. On the basis of this inquiry, it is possible to point out essential differences between spoken and written language and address these issues visually. The practical part then approaches the question of how the invisible concepts related
to our speech can be depicted, by experimenting with various typographical and letterform adjustments. Conducted experiments reflect the knowledge gained through the theoretical part, providing a fertile platform for a discussion.
