Oseledchik Sergei

I’m a professional Russian voice actor with a diverse background in radio broadcasting, audio editing, and sound design. My journey began in live radio, where I spent a year as a news host, mastering clear, expressive delivery and confident on-air presence.

I’ve also worked extensively as a sound designer and audio editor, handling full audio production — from recording to editing, sound design, and integration of music. Whether you need clean narration, polished mix-downs, or original audio elements, I can deliver broadcast-ready results tailored to your project.

In 2025 I was contracted by Mercor AI LLC, a San Francisco-based AI training and talent platform that collaborates with leading AI labs to teach and refine next-generation language models. In this role, I edited more than 3,000 minutes of audio recordings as an audio editor and served as a Russian voice actor, participating in training of models including Grok 4, helping improve natural Russian speech performance and accuracy.

My experience spans commercials, corporate narration, e-learning, YouTube content, and AI voice projects. I record from a treated home studio and deliver high-quality audio with a fast turnaround. If you’d like, I can share relevant samples based on your needs.
