World’s most accurate Russian speech-to-text
The world’s most accurate real-time speech-to-text API for Russian, powering voice agents, live systems, and applications across 60+ languages.
Trusted by teams building global voice products
Unmatched accuracy in Russian and 60+ languages
Russian is spoken by over 258 million people worldwide — across Russia, Belarus, Kazakhstan, Kyrgyzstan, and beyond. For years, Russian speech-to-text has fallen short, failing at fundamentals like accurate and reliable recognition, multiple languages, and alphanumerics. It converted Russian audio into words, but the words lacked meaning and context.
Soniox reimagined everything Russian speech-to-text got wrong. You can speak naturally, switch languages mid-sentence, spell out codes and names, or ask for instant Russian translation, all in real-time. Soniox doesn’t just transcribe Russian speech – it understands it.
Russian native-speaker accuracy
Accurate Russian speech recognition across accents, dialects, and real-world conversational speech.
“We tried a dozen speech-to-text and translation services. Soniox is the best, so that's what we use.”
Cayden Pierce, CEO/CTO at MentraAutomatically detect and switch languages with Russian
Soniox identifies the language automatically and follows changes between Russian and other languages as they happen, even within the same sentence.
