What Supertone does
Supertone is a South Korea-based AI voice technology company that develops text-to-speech synthesis, voice conversion, voice cloning, voice design, and audio enhancement products. The company operates a proprietary NANSY (Neural Analysis & Synthesis) foundation model that serves as the unified backbone for speech synthesis, singing synthesis, voice conversion, and voice design tasks, with research validated at top-tier AI conferences including ICLR, NeurIPS, and Interspeech. Supertone's product portfolio spans consumer-facing applications (Supertone Play for AI text-to-speech, Supertone Shift for real-time voice changing), professional audio plug-ins (Supertone Clear for de-noise and de-reverb separation, Supertone Air for reverb and EQ dialogue matching), and developer infrastructure (Supertone API plus Supertonic v3 on-device TTS with 31-language support and approximately 99M parameters in 404MB of ONNX assets). The company serves content creators, gamers, VTubers, game studios, broadcasters, entertainment companies, and enterprise integrators across Korea, North America, and Southeast Asia.
Supertone generates revenue through multiple streams: tiered subscriptions for consumer products (Play from $2.99 to $79.99/month; Shift from $3.99 to $14.99/month plus $149.99 perpetual voice purchases), one-time perpetual licenses for professional plugins ($69-$99), usage-based API pricing with enterprise custom tiers, and bespoke custom business solutions for large enterprise clients. The company employs a hybrid go-to-market combining self-serve product-led growth for consumers and developers with enterprise field sales for brand voice design, content production, and localization services. Marketing channels include YouTube, Instagram, TikTok, X, Discord, LinkedIn, Hugging Face, and earned media coverage in Korean outlets.
Supertone is a wholly-owned subsidiary of HYBE, the South Korean entertainment conglomerate, with co-founders retaining technical leadership following a CEO transition from Kyogu Lee to Hoon Heo. The company maintains strategic partnerships with HYBE's entertainment ecosystem, The Pinkfong Company (for the REDREX IP fan-creation collaboration), and a Voice Partners program with professional voice actors such as Jeong Jae-heon. Named enterprise customers include Netflix, Disney, Studio Dragon, HYBE, Pinkfong, Smilegate, Netmarble, Neowiz, Nexon, SBS, KBS, and LG.
