Supertone - AI voice intelligence platform for creative professionals

What Is Supertone

Have you ever wished you could instantly add professional voiceover to your YouTube videos without hiring expensive voice actors? Or wanted to transform your voice in real-time during a live stream without the lag that ruins the experience? Or spent hours trying to clean up noisy recordings for your podcast?

You're not alone. Content creators, streamers, game players, and media professionals face these challenges every day. Voice production is often time-consuming, costly, and technically demanding. That's where Supertone comes in.

Supertone is an AI voice intelligence platform built on a simple but powerful vision: "Beyond the Voice." This isn't just about mimicking voices—it's about understanding, resonating, and empowering creators with voice technology that actually works in the real world.

At the heart of Supertone's technology is NANSY (Neural Analysis & Synthesis), a unified neural framework for voice generation that has been published at leading AI conferences including ICLR, NeurIPS, and Interspeech. NANSY powers everything from text-to-speech synthesis to real-time voice conversion, maintaining consistent voice characteristics across generations while giving you control over four independent voice elements.

What does this mean for you? Whether you need to generate natural-sounding voiceovers in 23 languages, clone a voice for consistent multilingual content, transform your voice in real-time during gameplay, or clean up noisy audio recordings, Supertone has a solution designed for production workflows—not just demos.

The platform has already earned the trust of industry leaders. Netflix, Disney, HYBE, Smilegate, Netmable, Nexon, and Studio Dragon are among the companies using Supertone's technology. Their projects range from AI voice synthesis for entertainment content to real-time voice conversion for gaming and streaming applications.

Supertone's Core Features

Here's what you can actually do with Supertone—and how each feature solves real problems creators face every day.

Play: AI Voice Generator

You can use Play to turn text into natural, expressive speech in minutes. Whether you're producing YouTube videos, creating audiobooks, hosting a podcast, or recording ad voiceovers, Play handles the heavy lifting. It supports 23 languages and offers 50+ voice styles so you can match tone and emotion to your content.

What makes Play special is its voice cloning capability. With just 10 seconds of audio samples, you can create a synthetic voice that maintains consistency across multiple languages—a game-changer for content creators managing multilingual channels.

Shift: Real-Time Voice Changer

You can use Shift when you need instant voice transformation without compromising quality. Gamers love it for FPS games and VRChat; streamers use it for character roles and entertainment; podcasters leverage it for creative segments. The key advantage: low-latency voice conversion that runs on ordinary hardware—no GPU required.

Shift offers 100+ character voices, with 3-5 new voices added every month. Your options stay fresh, whether you want to sound like a fantasy character, an animated hero, or simply disguise your voice for privacy.

Clear: Noise Reduction & De-Reverb Plugin

You can use Clear to clean up audio in seconds rather than hours. This plugin tackles two common post-production headaches—background noise and room reverb—with simple, intuitive controls. Three knobs (Voice, Ambience, Reverb) let you dial in the right balance without a steep learning curve.

Clear supports AU, VST3, VST, and AAX formats, making it compatible with all major digital audio workstations. Whether you're live streaming, editing a podcast, or preparing voice recordings for video, Clear integrates seamlessly into your existing workflow.

Air: Reverb & EQ Dialogue Matching

You can use Air when you need to match dialogue to an acoustic environment quickly. Film and TV post-production teams use this for ADR (automated dialogue replacement)—the process of re-recording actor lines to replace unusable production audio. Air captures early reflections and matches reverb characteristics in seconds, dramatically speeding up what traditionally takes hours of manual adjustment.

Supertone API: Developer Integration

You can use the API to embed Supertone's voice technology directly into your applications. The RESTful interface supports text-to-speech synthesis, voice cloning, voice conversion, and source separation. With request rates ranging from 20 to 60 requests per minute depending on your plan, it's built for production-scale workloads.

Developers use the API to build AI character chatbots, automate audiobook narration, generate news broadcasts, and localize content into multiple languages while maintaining a consistent brand voice.

On-Device: Local Voice AI

You can run voice AI locally when internet connectivity is unreliable or privacy is paramount. Supertonic 2, accessible via Hugging Face, processes everything on-device—ideal for applications requiring offline operation or strict data residency.

Who's Using Supertone

Understanding how others use a tool helps you see whether it's the right fit for your needs. Here's a breakdown of who's benefiting from Supertone across different user segments.

Content Creators

If you're a YouTuber, podcaster, or audiobook creator, you likely face two persistent challenges: high voiceover costs and multilingual content production. Recording professional voiceovers takes time, and hiring voice actors for every project adds up quickly.

With Play, creators generate studio-quality voiceovers in 23 languages from a single text input. A creator managing a channel in English, Spanish, and Korean, for example, can produce all three versions with a cloned voice that sounds consistent across languages. The result: content production scales without multiplying costs or compromising quality.

Gamers and Streamers

If you play competitive FPS games, stream on Twitch, or VTuber, you need real-time voice conversion that doesn't lag. Traditional voice changers introduce delays that ruin immersion—or require expensive hardware that's out of reach for most users.

Shift solves both problems. It delivers low-latency voice conversion on everyday devices, so you sound like a fantasy warrior in-game without waiting for processing. With new character voices added monthly, there's always something fresh for your next stream or gaming session.

Post-Production Engineers

If you work in film, television, or podcast production, you know how noise and reverb can derail an otherwise great recording. Cleaning up audio traditionally requires expensive plugins, specialized skills, and significant time.

Clear removes background noise and reverb with three simple controls—no audio engineering degree required. Air speeds up ADR workflows by matching dialogue to environmental acoustics in seconds. Together, they help you achieve professional-grade audio quality in a fraction of the time.

Enterprise Developers

If you're building AI-powered applications—whether that's a character chatbot, an audiobook production pipeline, or a content localization system—you need scalable voice technology that integrates smoothly.

The Supertone API, combined with Enterprise plan benefits like volume discounts, dedicated account management, and priority support, gives developers the flexibility to build production systems without worrying about rate limits or infrastructure constraints.

Media Companies

Major entertainment companies including Netflix, Disney, HYBE, and Studio Dragon rely on Supertone for large-scale voice content production. These organizations need consistent quality, reliable performance, and the ability to generate voice content at scale—exactly what Supertone delivers.
