VoiceStudio (free, open source)
An open-source studio for voice cloning, voice design, dubbing, dictation and audiobooks, with installers for Windows, macOS and Linux. Its default engine covers hundreds of languages, and you can switch engines. The app is AGPL-3.0; each model has its own licence, which the app shows but doesn't vouch for.
Voicebox (free, open source)
A desktop voice-cloning studio built originally on Qwen3-TTS, now with more engines to choose from. It clones from a few seconds of audio and runs on your machine, with builds for Mac and Windows; from source it needs a Python setup.
Pinokio with F5-TTS or AllTalk (free)
Pinokio is a free one-click launcher for open-source AI apps. It installs web interfaces such as F5-TTS's and AllTalk (which runs XTTS-v2, F5-TTS and others) without you typing commands. It still builds Python environments behind the scenes, takes several gigabytes, and is easiest with an NVIDIA graphics card.
Command line (free)
Each model above installs with pip and comes with examples. Most flexible, most work: Python, PyTorch for your graphics card, and FFmpeg.
VoicedByMe ($30 once)
A normal installer for Windows 10 and 11 and Macs with Apple silicon. Clone your voice from twenty seconds, or use 70 ready-made voices, then use it everywhere: read any app's text, make audiobooks with chapters, send voice notes, give AI agents a voice, or call its OpenAI-compatible API. Its output is watermarked and labelled as AI-made. It speaks English, Spanish, German, French, Portuguese, Italian, Japanese and Russian.
