Voice Intelligence Platform Supertone delivers a suite of AI-powered audio tools built to handle the full spectrum of voice production needs. This system centers on four main products: Play for text-to-speech generation, Shift for real-time voice changing with over 100 voices available free monthly, Clear for audio de-noising and de-reverbing, and Air for dialogue matching in ADR workflows. It supports multilingual synthesis across English, Japanese, and Korean, while its Voice Separator functionality isolates vocal tracks from complex audio. Supertone partners with professional voice actors like Jeong Jae-heon—known for dubbing Nick Wilde in Zootopia and characters in Demon Slayer—to create AI voice characters that preserve subtle breath patterns, emotional range, and lifelike vocal details. Play requires no sign-up for basic access, while Clear and Air offer downloadable trial versions.
This system serves audio production professionals handling ADR engineering, content creators building videos or podcasts, game streamers seeking voice variety, and VRChat users customizing their virtual presence. Voice actors exploring AI collaboration find value in the Voicd Partners program, which compensates performers while expanding their digital reach. Businesses requiring voice AI integration can tap into the API for custom implementations. These tools scale from individual creators experimenting with free voice options in Shift to production studios managing complex dialogue replacement workflows with precise reverb and EQ matching.
ADR engineers use Air to match replacement dialogue with original scene acoustics, adjusting reverb and EQ parameters until new recordings blend naturally with existing footage. Podcasters run raw recordings through Clear to eliminate background noise and room echo before publishing. Content creators generate multilingual voiceovers through Play's text-to-speech engine, selecting from custom voice characters that maintain consistent emotional tone across long-form content. Streamers switch between character voices mid-broadcast using Shift's real-time processing, while game developers integrate the speech synthesis API to generate dynamic NPC dialogue. Its plug-in architecture fits directly into existing audio production software, letting professionals add AI voice capabilities without disrupting established workflows or learning new interfaces.
