Respeecher develops voice conversion technology that transforms one person's speech into another's voice while preserving emotional delivery and performance timing. The company was founded in 2018 by Alex Serdiuk, Dmytro Bielievtsov, and Grant Reaber, and is headquartered in Kyiv, Ukraine.
Respeecher's technology has been used in film and television production for dialogue replacement, de-aging voice work, and localization, as well as in video game development for character voice generation. The company has worked on projects including voice work for characters in the Star Wars franchise for Lucasfilm, and its tools have been applied in dubbing, audiobook production, and dialect conversion.
The company has raised venture funding from investors including Sunflower Capital and other backers, with disclosed funding in the single-digit millions of dollars. Respeecher operates with a distributed team and continues to serve studios, media companies, and game developers through licensing and API-based integration.

Who Respeecher competes with, and how they differ.
The scale leader in AI speech, selling self-serve text-to-speech, dubbing and an open voice library on developer-priced API and subscription tiers. Respeecher sells a studio service built on speech-to-speech conversion, per-project licensing and documented talent consent rather than high-volume self-serve.
1 product reviewed on TopReviewedThe closest technical analogue: speech-to-speech conversion and voice cloning sold as an enterprise API, bundled with its own audio deepfake-detection product. Resemble leads with the developer platform, while Respeecher's business is anchored in film, TV and AAA game post-production credits.
1 product reviewed on TopReviewedIsrael-based and focused on end-to-end localisation and dubbing of film and TV into other languages, competing for the same studio post-production budgets. Respeecher does localisation too but as often sells voice replacement, de-ageing and archival recreation in the original language.
1 product reviewed on TopReviewedSelf-serve text-to-speech voiceover aimed at corporate e-learning, marketing and explainer-video budgets on a subscription studio model. It overlaps Respeecher's Voice Marketplace tier for creators, not the bespoke entertainment engagements that make up Respeecher's core work.
1 product reviewed on TopReviewedReal-time voice changing distributed as a free consumer desktop app with paid voice packs for gamers and streamers. It shares Respeecher's speech-to-speech approach but targets live consumer use rather than consent-cleared, licensed reproduction of a named performer's voice.
