Low-latency, dynamic voices for gaming

Diverse voice library

Choose from a growing catalog of production-ready AI voices to match the tone, role, and personality of your game characters. From a wise, otherworldly wizard to a commanding sportscaster, our voice library gives you instant access to high-quality, expressive voices. Also, find specialized native-speaking voices across 15+ languages and regional accents, available out of the box.

Voice cloning

Build your own custom voice library with Sonic’s Pro Voice Cloning and Instant Voice Cloning. From grizzled assassins to cheerful shopkeepers, you can bring your NPCs, heroes, and companions to life with expressive, game-ready voices that are all yours. Use your own voice source—voice actors, archived recordings, teammates, or even your own voice.

Voice changer

Experiment with a range of voices until you find the perfect match. Record scripts to establish timing, emotion, and delivery—and then instantly “audition” different voices to “read” your recording. They’ll mimic every pause, inflection, and tone—while making it sounds like anything from an intergalactic overlord to a mischievous elf.
