VoxCPM2

VoxCPM2 is an open-source text-to-speech (TTS) model from OpenBMB, designed for developers needing high-fidelity voice synthesis with an Apache-2.0 license. Unlike closed-API solutions, VoxCPM2 allows for local deployment, giving you full control over data privacy and latency. It is optimized for natural prosody and clear articulation, making it suitable for integrating into accessibility tools, automated content creation, or interactive AI agents. For developers, the primary draw is the balance between computational efficiency and output quality, allowing it to scale across various hardware configurations without requiring massive GPU clusters for inference.

Download this model

We recommend using the ModelScope CLI or SDK. Install ModelScope first, then choose a full snapshot, single file, SDK or Git LFS workflow.

This entry points to Hugging Face. The commands use the matching ModelScope repository format; confirm that the repository exists on ModelScope before running them. Model repository: openbmb/VoxCPM2
Install ModelScope

Install the CLI and SDK dependency before downloading.

pip install modelscope
Download the full model repository

Download the complete weights, configuration and model card.

modelscope download --model openbmb/VoxCPM2
Download one file to a local directory

README.md is used as an example; replace it with another repository file when needed.

modelscope download --model openbmb/VoxCPM2 README.md --local_dir ./dir
Download with the SDK

Useful in Python projects and automation scripts.

from modelscope import snapshot_download
model_dir = snapshot_download('openbmb/VoxCPM2')
Clone with Git

Make sure Git LFS is installed correctly.

git lfs install
git clone https://www.modelscope.cn/openbmb/VoxCPM2.git
Clone without downloading LFS blobs

Fetch the repository structure first, then pull large files when needed.

GIT_LFS_SKIP_SMUDGE=1 git clone https://www.modelscope.cn/openbmb/VoxCPM2.git
