The study deals with the analysis of suprasegmental qualities in Slovak child directed speech (CDS). Based on the audio-records of two mothers (M1 and M2) in verbal ineraction with their 11 months old children (M1 with her daughter, M2 with her son) and separately with their adult relatives (AS), the four basic hypotheses – (a) the voice pitch is higher in CDS than in AS; (b) melody in CDS is more variable and expressive and also with greater tone intervals than in AS; (c) the average speechtempo is lower in CDS than in AS; (d) pauses in CDS are in average longer than in AS – are verified and proved by the experimental and statistic methods.
