Altered Studio
Altered Studio combines voice transformation and audio production tools for creating professional voice content. Its Speech-to-Speech and Performance-to-Performance morphing changes a voice while retaining the speaker’s performance. Other tools include text-to-speech, voice cloning, AI voice cleaning, denoising, audio editing, DSP effects and batch processing. Studio supports transcription and translation in 75+ languages, and text-to-speech voice-over in 70+ languages. A Rapid Voice Clone can be made from 4–8 seconds of audio; custom voice models are available by contacting Altered. The online Voice Editor can work with Google Drive audio, while RealTime Pro routes audio through a virtual microphone to apps including Discord, Zoom, Microsoft Teams and Google Meet. The free plan includes 3 minutes per month of voice morphing and 10,000 AI tokens. Creator costs $30 a month billed annually; Professional costs $90 a month billed annually. Desktop use requires a Windows PC with an 8GB+ Nvidia GPU, and mobile devices are not currently supported.
