The thesis presents a phonetic analysis of speech techniques used by eight radio presenters – four of which were selected from the non-commercial Val 202 and four from the commerical Radio 1. The analysis included thematically and temporally similar recordings, which were at first limited to app. 30 seconds and were then further reduced to app. 5 seconds. Longer recordings were analyzed, transcribed and marked with stresses, pauses and intonations using Praat. These enabled us to measure the rate of speech. Using Overtone Analyzer, the shorter recordings were analyzed to determine the number of words and timbre.
The results revealed that Radio 1 presenters speak too loudly with the use of too many stresses, whereas Val 202 presenters speak too slowly but with the appropriate use of pauses and pitch. The presenters emphasize different words and not just a particular class of words. Although the intensity is heavily influenced by background noise, the presenters themselves are intentionally louder so as to attract the attention of the audience. Timbre tends to be the most important factor in the recognizability of the presenter, however it is also determined by other speech elements. The timbre of Gov002M (Radio 1) is the most recognizable, followed by Gov007M (Val 202). Based on all the recorded speech parameters Gov003M (Val 202) has the best and most appropriate radio voice, whereas Gov004M (Radio 1) has the least. However, everything doesn't depend only on measurements. The choice, who is a recognizable speaker, is primarily a matter of perception and acceptance of the listeners.
