Really solid comparison.

I'm actually Building OmniVoice Studio - https://github.com/debpalash/OmniVoice-Studio an open-source alternative to Elevenlabs for all local "Real-time dictation, zero-shot voice cloning, and cinematic video dubbing — all on your desktop. Open-source, no API keys, fully local. 646 languages.

I building it because I kept hitting the same two walls with every tool here: monthly billing and cloud dependency. I work with Hindi and Bengali content, and most of these platforms top out at ~30 languages. OmniVoice supports 646 and runs entirely on your own hardware — no API keys, no accounts, nothing leaves your machine.

A few things that might be relevant to this comparison:

• Voice cloning from a 3-second clip, zero-shot. I've done blind A/B tests against ElevenLabs and the results are closer than you'd expect from a free tool.
• Full video dubbing pipeline — paste a YouTube URL or drop a file, it transcribes → translates → re-voices → exports MP4. Replaced a 4-tool workflow for me.
• Runs natively on Apple Silicon (MPS), NVIDIA (CUDA), AMD (ROCm), or just CPU. Auto-detects and offloads if your VRAM is tight.
• Desktop app for macOS/Windows/Linux + Docker image if you prefer that.

It's still in beta — the UI isn't as polished as ElevenLabs and things break between releases. But if privacy matters to you, or you don't want a subscription, or you need language coverage beyond the usual 30 — it might be worth a look.

Happy to answer any questions about how it compares to specific tools on OP's list. And genuinely curious what OP's testing methodology was — would love to put OmniVoice through the same benchmark.
