ComfyUI-VoxCPM and ComfyUI-ChatterboxTTS
These tools are competitors, as both provide ComfyUI nodes for text-to-speech functionality, with VoxCPM focusing on expressive speech and zero-shot voice cloning, while ChatterboxTTS emphasizes production-grade open-source TTS.
About ComfyUI-VoxCPM
wildminder/ComfyUI-VoxCPM
ComfyUI node for highly expressive speech and realistic zero-shot voice cloning
Implements a tokenizer-free diffusion-based TTS architecture built on MiniCPM-4 that models speech in continuous space rather than discrete tokens, enabling context-aware prosody generation. Includes native LoRA fine-tuning support within ComfyUI for custom voice style training, automatic model management with efficient VRAM offloading, and operates at 6.25Hz token rate for faster synthesis on consumer hardware. Integrates seamlessly with ComfyUI's node workflow system, supporting optional reference audio for voice cloning and compatible with multiple inference backends (CUDA, CPU, MPS, DirectML).
