What Respeecher does
Respeecher is a Kyiv-based AI voice synthesis company founded in 2018 by Alex (Oleksandr) Serdiuk, Dmytro Bielievtsov, and Grant Reaber. It builds high-fidelity voice cloning and voice conversion systems using deep neural networks that combine public foundation models with proprietary technology tuned by an in-house AI Voice Lab of 15+ sound professionals. Its two underlying capabilities are Speech-to-Speech conversion (which translates a live actor's performance into a target voice while preserving emotional nuance, timing, and breath) and neural Text-to-Speech (with a sub-200ms real-time variant), supporting multilingual generation, cross-language accent preservation, and emotion transfer.\n\nThe company distributes its technology through three primary channels: AI Voice Lab, an enterprise direct-sales motion delivering custom voice models and sound-engineering support for major film, TV, and game productions; the Voice Marketplace, a self-serve library of 40+ AI voices with a Pro Tools plugin for audio professionals; and Respeecher Space, a Real-Time TTS API priced at $2/hour with Python and TypeScript SDKs and pre-built integrations with LiveKit, Pipecat, Ultravox, and VAPI for developers building voice agents. Revenue also includes licensing royalties from celebrity and voice-actor marketplace voices, with at least 25% of revenue shared back to talent.\n\nRespeecher's customer base spans film and TV studios (Lucasfilm/Disney+, A24, Sony Pictures Television, Blumhouse), AAA gaming (CD Projekt RED, Sony Interactive Entertainment), music (Warner Music France, Aloe Blacc), advertising (Mondelēz/Ogilvy, DDB, Droga5), audio platforms (Deezer, Calm), sports broadcasting (IOC/Paris 2024, Religion of Sports), and developer tooling (MacPaw's Eney assistant). The company has been awarded an Emmy, a Webby, and a CLIO, and operates from Ukraine while serving global clients — a posture that carries both cost advantages and war-related operational risk.
