A 5 twin pairs and control group of 10 singletons participated in the present study. The study of a cohort of all twin children born between 1 January 2010 and 31 May 2011 was carried out at Saint-Petersburg Hospital №17.

The following methods were used: children voice recording (model situation: the game with mother, reading a book by mother, play with laptop); perceptual analysis of speech signals (n = 24, the auditor); acoustic spectrographic analysis («Cool Edit Pro 2.0»). The study confirmed the hypothesis that 3-4 years old twins have significantly higher the pitch values than singletons. The pitch va
