Why teams choose Soniox over Deepgram for Russian
Engineered for real-world accuracy in Russian.
Soniox delivers production-grade accuracy in Russian and 60+ languages. It understands fast, informal, accented speech in Russian, and handles mixed-language phrases, spoken codes, and alphanumerics with precision that others miss.

Developers choose Soniox for accuracy in Russian speech
Russian is spoken by 258 million people worldwide — across Russia, Belarus, Kazakhstan, Kyrgyzstan, and beyond. Soniox delivers production-ready transcription and translation for Russian, handling regional accents, code-switching, and real-world audio conditions. Deepgram lists Russian as supported, but benchmark results show far higher error rates compared to Soniox.
Developers often like Deepgram for getting started quickly but often have to sacrifice accuracy, streaming speed, and key features. In real-world Russian audio, which can include accents, rapid speech, and overlapping speakers, errors increase, streaming lags, and translation isn't included. Soniox offers one API that transcribes and translates Russian (and 60+ others) with higher accuracy and smoother real-time performance, so your app instantly works worldwide.
