The article analyzes realization of voiceless and voiced plosive consonants in the speech of the Russian-speaking bilingual children of Germany reading aloud a phonetically representative text. The author measures bilingual children’s voice pause period regarding the instant of explosion of voiced plosive consonants (the start time of vocalization - STV), since she considers it the most reliable acoustic indicator to differentiate between voiceless and voiced consonants. Voiced plosive consonants STV characteristics differ in the Russian and German languages; consequently, inter-lingual phonetic interference occurs.
