In their own words
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.
VoiceStudio
VoiceStudio is an open-source voice AI studio for local voice cloning, voice design, video dubbing, dictation, transcription and audiobook creation. Users can describe a voice by gender, age, accent, pitch and emotion without providing reference audio. Its dubbing workflow transcribes and translates video, then re-voices it while keeping speakers separate and aligning timing with the original. Users can create multi-voice audio from scripts and chaptered audiobooks from long text or EPUB files. The desktop app exposes a local OpenAI-compatible API for speech, voices, transcription and dubbing. The maker lists 26 adapters, including local text-to-speech and transcription engines and a configured-remote ASR adapter. The maker says recordings, generated audio, transcripts and derived voice data stay on user-controlled storage and are not received by its website or control plane. The app may access the network for updates, model downloads or explicitly network-backed adapters. The public build has no hosted dashboard or Cloud API. Open Source costs nothing under AGPL-3.0; Pro costs $99 a year and Lifetime costs $299, paid once. Speech model licences are separate.
