Understanding Russian CAF files
Standard Russian is unusually uniform for a language of its size, with Northern, Central, and Southern dialect groups inside Russia differing mainly in vowel pronunciation. The variation transcription users encounter most is second-language accents from speakers across the post-Soviet states, along with occasional code-switching into Ukrainian, Kazakh, or other regional languages.

Frequently asked questions
How to improve the accuracy of your Russian transcripts?
Start by improving the quality of the Russian CAF file that you upload to Sonix. Please use high quality recording equipment, recording in a quiet environment, and ensure that your speakers are speaking clearly to ensure that your transcript is as accurate as possible.
Any advice for the Russian CAF file that I upload?
Yes, please do not over-compress or over-filter the audio track of your Russian CAF file. By uploading a high quality version of your audio, we can give you the best level of accuracy.
Aside from CAF, do you support other types of audio/video files?
Yes, we do! You can convert the following file types in Russian with Sonix:
Why won't my CAF file play on Windows?
CAF is an Apple container that most Windows applications do not support natively. You can open it with a third-party player such as VLC, or convert it to WAV or MP3 for broader compatibility.
How large can a CAF file be?
CAF uses 64-bit file offsets, so there is no practical size limit and recordings can run for many hours. This is the main advantage over WAV and AIFF, which are capped at 4 GB.
Can Sonix transcribe Russian audio recorded outside Russia, such as in Kazakhstan or the Baltic states?
Yes. Sonix's Russian model transcribes Russian speech regardless of where it was recorded, and the built-in editor lets you correct any words affected by regional accents.
Does Sonix output Russian transcripts in Cyrillic?
Yes. Russian transcripts are produced in the Cyrillic script and can be exported to Word, PDF, plain text, and subtitle formats such as SRT and VTT.
Can Sonix translate a Russian transcript into English?
Yes. After transcribing a Russian file, you can use Sonix's translation feature to generate an English version of the transcript, then review and export it.
Trusted by professionals worldwide
The entire process is extremely straightforward and what I liked most was the accuracy of the transcriptions and translations. I must say, I had some doubts as to what the quality would be like since it was in French, but I was not disappointed in the least.
I was amazed that Sonix picked up words that I couldn't even understand.
