ComfyUI VoxCPM
Open-source 30-language diffusion TTS with voice cloning, voice design, and LoRA customization, running locally in ComfyUI.
VoxCPM2 is the strongest open-source choice when you're already in ComfyUI and need multilingual voice cloning plus LoRA-style customization without cloud dependence. It crushes hosted APIs on privacy and control, but the GPU requirement and non-real-time inference mean it's not for everyone—skip it if you need a simple API or low latency.

Skip VoxCPM2 if you need a managed cloud API, real-time streaming, or low-latency inference—it's local-only and diffusion TTS is slow.
No monetary cost, but you'll need a GPU with adequate VRAM (at least 8GB) and technical expertise to set up ComfyUI and the model, which can take hours.
VoxCPM2 is free and open-source (Apache-2.0), making it the most budget-friendly option for individual developers and researchers, especially compared to commercial TTS APIs like ElevenLabs (which charges per character) or Azure Speech (which charges per million characters).

About ComfyUI VoxCPM
ComfyUI VoxCPM (VoxCPM2) is an open-source, diffusion-based text-to-speech model from OpenBMB that handles 30 languages—from English and Chinese to Arabic, Burmese, Khmer, and Swahili—all within a tokenizer-free architecture designed for context-aware speech generation and true-to-life voice cloning. You run it locally inside ComfyUI, so instead of a black-box API, you get visual, node-based workflows that chain TTS directly with your other generation nodes. Since the weights are Apache-2.0 licensed safetensors (about 2.29B BF16 parameters, roughly 4.6GB), you can use it commercially, modify it freely, and keep your audio data on-device. The model supports voice cloning with controllable similarity, plus voice design straight from text prompts—no reference audio required—and LoRA training lets you steer a voice toward a specific character or style. Output is 48kHz audio with controls over emotion, prosody, and similarity, which makes it a fit for game character voices, multilingual narration, and research prototypes. Recent momentum is strong: the Hugging Face repo shows over 2.2 million all-time downloads and 1.53k likes as of mid-April 2026, with active maintenance (last modified April 16, 2026). For tech-savvy users, the appeal is the combination of local privacy, deep customization, and the ComfyUI integration—your audio never leaves your machine, and you can adapt voices with LoRA. But this is not a plug-and-play service. You need a capable GPU, comfort with model deployment, and tolerance for slower, non-real-time inference—diffusion TTS is not built for low-latency streaming. If you want a simple REST API or real-time latency, ElevenLabs or Azure Speech remain better options. For those who value control, privacy, and local fine-tuning, VoxCPM2 is the open-source option to beat.
Behind the Verdict
VoxCPM2 stands out among open-source TTS because it doesn't just offer a single voice; it gives you cloning, designing, and LoRA fine-tuning. The 30-language support is genuinely broad, covering languages like Burmese, Khmer, and Swahili that many commercial APIs skip. The diffusion-based generation produces 48kHz audio with emotion and prosody controls, which is uncommon in open models. The tight ComfyUI integration is a major plus for those already using that ecosystem—you can wire TTS into image-to-video or other generation workflows directly. The Apache-2.0 license and safetensors format make it commercially usable. However, this is not a tool for everyone. You'll need a GPU with enough memory (about 4.6GB just for weights, plus overhead), and inference is non-real-time. Diffusion TTS typically takes seconds per utterance, so it's unsuitable for live streaming. There's also no managed API or simple REST interface; you must run it locally, which adds setup overhead. For a content creator who wants quick voiceovers without technical fuss, a hosted service like ElevenLabs or Azure Speech is more practical. But for developers, researchers, and privacy-conscious teams who need on-premise generation and customizable voices, VoxCPM2 is a top contender. The active community and high download counts suggest it's well-maintained and likely to improve.

Setup time & first value
How long it actually takes to get something useful out of ComfyUI VoxCPM — broken out by persona, not the marketing-page minute.
For a tech-savvy user: 1-2 hours to install ComfyUI, download the model (~4.6GB), and run your first generation. If you're new to ComfyUI, allow 3-4 hours to learn the interface and set up the node graph.
Switching to or from ComfyUI VoxCPM
How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.
- →From ElevenLabs or similar hosted APIs: download VoxCPM2 weights and run locally for unlimited, privacy-preserving generation, though you'll need to build your own integration and manage GPU resources.
- ↗To another open-source TTS (e.g., Coqui TTS): both are free, but VoxCPM2 offers broader language support and LoRA customization, so you might switch back if you need those features.
- ↗To a commercial service (ElevenLabs/Azure Speech): if you need real-time streaming or simpler integration, you can migrate your voiceover pipeline to their APIs, though you'll incur per-character or per-minute costs.
