This bachelor thesis deals with the internal and external variation in speaker's assessments based on speech performance. Using the material of two poems ("Portrét" by Karel Toman and "Píseň zhýralého jinocha" by František Gellner), the variability in the evaluation of the recordings of 32 speakers (16 women and 16 men) was studied. Their performance was rated by 30 listeners on a seven-point scale based on their impression of the overall recitation. The general nature of the perception test instructions allowed us to observe which factors may play an important role in the perception of the overall speech performance. The results point, among other things, to the possible influence of the text of the poems on respondents' assessments. This study serves as a basis for further in-depth research in the area of speech assessment. Keywords: internal variation, external variation, voice perception, voice attractiveness, voice measurement, voice assessment, recitation
