Grammar Rule in 30 Seconds

Russian consonants often change their sound based on the letter that follows them to make speaking easier.

  • Voiced consonants become voiceless at the end of a word: 'год' sounds like 'гот'.
  • Voiced consonants become voiceless before a voiceless consonant: 'водка' sounds like 'вотка'.
  • Voiceless consonants become voiced before a voiced consonant: 'футбол' sounds like 'фудбол'.
Voiced + Voiceless = Voiceless | Voiceless + Voiced = Voiced

“Глаз (eye) -> [глас]”

“Друг (friend) -> [друк]”

Regressive Assimilation

A consonant changes its voicing to match the consonant immediately following it.

“Сделать (to do) -> [зде-] (voiced s)”

🎯

The Vowel Rescue

If you aren't sure if a word ends in 'б' or 'п', put it in plural. 'Хлеб' becomes 'Хлебы' (archaic) or look at 'Хлеба'. The vowel makes the real sound clear!
⚠️

Don't Spell Phonetically

Russian is not written exactly as it sounds. Always check the dictionary spelling, especially for consonants at the end of words.
💬

The 'V' Exception

Remember that the letter 'В' is weak. It won't make the letter before it voiced. In 'твой' (your), the 'т' stays voiceless.

Smart Tips

Check if it's a voiced consonant and devoice it.

друг (hard g) → друк (soft k)

Match the voicing of the second consonant.

водка (d) → вотка (t)

Voice the 'с' to 'з'.

сделать (s) → зде- (z)

Devoice the 'в' to 'ф'.

в саду (v) → ф саду (f)

发音

друг -> [друк]

Final Devoicing

Always make the final consonant voiceless.

Statement

Это друг. ↘

Falling intonation for facts.

记住它

记忆技巧

Remember 'B-P, V-F, G-K, D-T, Zh-Sh, Z-S'. These are the pairs that swap.

视觉联想

Imagine a light switch. When a voiceless consonant (the 'off' switch) appears, it turns the vibration of the previous voiced consonant 'off'.

Rhyme

When the end of the word is near, the voiced sound will disappear.

Story

A friend (друг) walks into a shop. He is a voiced person. But the shopkeeper is a voiceless person. As soon as he enters, he becomes quiet and voiceless too. They both speak in whispers.

Word Web

挑战

Read 5 words aloud, exaggerating the voicing change, then record yourself and listen back.

文化笔记

Russians value clear, rhythmic speech. Assimilation is part of that rhythm.

Ukrainian has different voicing rules, which can confuse learners.

Similar to Russian but with specific soft consonant rules.

These rules evolved from Proto-Slavic to simplify articulation.
