Generate multilingual speech with an Apache-2.0 TTS model for voice cloning, voice design, and self-hosted 48kHz audio output.

Skip if you need a hosted API with support, billing, and uptime guarantees.
The open model and code are useful for studying multilingual and controllable speech generation.
Skip if your needs are simple narration clips and you do not have GPU access.
Cloud text-to-speech APIs are convenient, but high-volume voice generation can become expensive and constrained by provider limits. Teams building voice products also face privacy questions when scripts, prompts, reference voices, or generated audio pass through a third-party API.
Multilingual voice work adds another problem: quality and style controls vary by language, and many tools force developers into a fixed hosted model with limited room for research or product-specific tuning.
Targets multilingual TTS use cases where developers need one project for multiple languages and voice styles.
Supports workflows around reference voices and controllable voice generation for custom voice applications.
The Apache-2.0 project lets AI teams run and adapt the model locally instead of paying per character to a hosted API.
VoxCPM is a stronger fit for teams that need to run multilingual text-to-speech and voice cloning on their own infrastructure. ElevenLabs is easier to start with because it is a hosted commercial product, but VoxCPM avoids per-character usage pricing and keeps prompts, reference voices, and generated audio inside the operator's environment.
Azure AI Speech gives enterprises a managed cloud service with support, billing, and production uptime handled by Microsoft. VoxCPM asks the team to own GPU serving and model operations, but it gives researchers and builders direct access to an Apache-2.0 model for experiments, privacy-sensitive workloads, and product-specific speech generation.
Yes. VoxCPM is open source under the Apache-2.0 license.
VoxCPM is used for multilingual text-to-speech, voice cloning, and controllable voice generation.
ElevenLabs is a hosted voice generation service. VoxCPM is an open source model path for teams that can operate speech generation themselves.
