Inside the product
What you can actually do with it.
The core product capabilities, grouped around the work they enable.
Text-to-speech creation
Supertone Play lets users select a character voice, enter a script, and adjust pitch, pitch variance, and speed before generating audio.
Real-time voice conversion
Supertone Shift changes a speaker's voice into selected character voices in real time.
Audio cleanup
Supertone Clear is an audio plug-in for reducing noise and reverb and separating voice from background sound.
Typical workflow
Choose the Supertone product for the job, such as Play for text-to-speech and dubbing, Shift for voice conversion, or Clear for audio cleanup. In Play, select a voice, enter a script, tune voice settings, and generate audio; developers can instead create an API key and call the REST API.
