Profile

Supertone is an AI voice company offering a real-time voice changer (Shift), a voice-cloning/TTS creation app (Play), and a developer API, aimed at gamers, streamers, V-Tubers, dubbing studios and developers who need expressive synthetic voices. Its products run on credit-based tiered subscriptions, each with a free entry tier, scaling from a few dollars a month for hobbyists up to roughly $80/month for high-volume creators, plus custom Enterprise pricing.

Who builds it

Supertone is built by Supertone Inc., a South Korean voice-AI company. Shift lets users transform their live voice into a chosen character in real time during calls, games or streams; Play and the API let users clone a voice from a short sample or generate speech from text with adjustable emotion, pitch and speaking style.

Core features

  • Real-time, low-latency voice conversion (Shift) into 100+ free character voices and 150+ premium voices, running without a GPU on Windows/macOS
  • Voice cloning from roughly a 10-second sample on Play/API, usable across supported languages while keeping the cloned voice's character
  • Emotionally expressive TTS with 50+ selectable styles and adjustable pitch, intonation and speaking speed
  • Multilingual voice generation across 23 languages on Play, including Korean, English, Japanese, Spanish, French, German and more
  • AI dubbing and voice-separation tools (extracting a speaker's voice from background audio) on Creator-tier and above
  • Two selectable models — Supertonic (efficient, more audio per credit) and Sona (higher expressiveness, more credits per generation)

Pricing

  • Shift: Free (limited voice access, 3-5 new voices/month); Starter $3.99/month (full access to 40 basic voices); Pro $14.99/month (basic + pro voice libraries); Perpetual $149.99 one-time per individual voice for lifetime access
  • Play / API: Free $0/month (~5 min/month usage, 3,000 credits); Starter $2.99/month (~30 min/month, 20,000 credits, voice cloning via upload); Creator $14.99/month (~300 min/month, 100,000 credits, AI dubbing); Pro $79.99/month (unlimited usage, 500,000 credits, highest API rate limits); Enterprise custom pricing
  • Introductory/promotional discounts (e.g. 50% off Starter) have been advertised on Supertone's site — check supertone.ai for currently active pricing before committing
  • Check supertone.ai/en/shift, supertone.ai/en/play and supertone.ai/en/api for current rates, since tiers and credit allowances can change

Who it's for

Gamers, streamers and V-Tubers who want to sound like a character in real time fit Shift, starting from its free tier up to Pro for full voice-library access. Creators producing narration, dubbing or cloned-voice content should use Play, scaling from the free tier through Creator or Pro depending on monthly minutes needed. Developers embedding TTS, voice cloning or voice conversion into their own apps should use the Supertone API tiers, which mirror Play's pricing but add programmatic access and per-minute API rate limits.

Frequently asked questions

What does Supertone cost?

Supertone sells two related product lines: Shift (the real-time voice changer), priced Free up to $14.99/month for Pro plus a $149.99 one-time Perpetual voice purchase, and Play/API (voice cloning and TTS), priced Free up to $79.99/month for Pro, plus custom Enterprise pricing for both. Check supertone.ai's Shift, Play and API pages directly for current rates, since tiers and promotional discounts change.

Is Supertone free?

Yes, both Shift and Play/API offer a genuine $0 free tier. Shift's free tier gives limited access with 3-5 new voices added monthly, while Play/API's free tier includes about 5 minutes/month of usage and 3,000 credits with unlimited voice cloning. Higher usage, the full voice library, or AI dubbing require upgrading to a paid tier.

What languages and voices does Supertone support?

Supertone Play supports voice generation in 23 languages, including Korean, English, Japanese, Spanish, French, German, Italian, Russian, Portuguese, Hindi and more, backed by 150+ premium voices plus 50+ character voices. Shift, the real-time voice changer, offers over 100 free character voices and 150+ premium voices, focused on real-time conversion rather than multilingual TTS output.

Does Supertone support voice cloning?

Yes — voice cloning is a core Play/API feature: users upload roughly a 10-second audio sample to train a personal AI voice that can then speak naturally across Supertone's supported languages while keeping the original voice's character. Cloning access starts on the Starter tier ($2.99/month) via audio-file upload, while Shift's free tier separately advertises unlimited voice cloning with attribution required for commercial use.

Does Supertone have an API?

Yes, Supertone offers a dedicated developer API with the same tier structure as Play (Free, Starter, Creator, Pro, Enterprise), adding API-specific rate limits — from 20 requests/minute on Free up to 60 requests/minute on Pro. It covers TTS, voice cloning, voice conversion and voice separation, and supports two models (Supertonic for efficiency, Sona for higher expressiveness) that trade off credit consumption for audio quality.

What's the difference between Supertone Shift and Supertone Play?

Shift is a real-time voice changer for live use — it converts your live voice into a chosen character voice during calls, games or streams, running locally without a GPU. Play (and the matching developer API) is instead a creation tool for voice cloning and text-to-speech: you type a script or upload a voice sample and get back a rendered audio file in one of 23 languages, rather than a live-converted stream. Streamers and gamers who want to sound different in real time need Shift; creators producing narration, dubbing or cloned-voice audio files need Play or the API.
