The article is devoted to the analysis of the implementation of voiceless and voiced stop blasting consonants in the speech of Russian-speaking German bilingual children, when reading a phonetically representative text aloud. The author measures the delay time of the voice relative to the moment of explosion at the stop blasting consonants (voice on set time: VOT), since she considers it to be the most reliable acoustic parameter for distinguishing between voiceless and voiced consonants. The phonetic categories of VOT explosive consonants are different in Russian and German, so VOT can be exposed to interlingual phonetic interference.
