In their own words
Voice.ai
Voice.ai provides real-time AI voice transformation for PC, alongside text-to-speech and online audio tools. Its PC app describes its voice engine as deep-learning based and lets users hear a changed voice in real time. A library of user-generated voices and voice cloning are also listed. Voice.ai says transformed speech is returned in the speaker’s language. On Windows, it can work with microphone-enabled apps such as Discord, Zoom, Google Meet, WhatsApp, Skype and Twitch, plus games including Minecraft and Fortnite. The platform listing includes Windows, Mac, iOS and Android, while its API offering covers voice agents, cloning and text-to-speech. The free plan includes 5k credits/month and a five-minute audio conversion limit. Starter costs $5 a month and includes 15k credits/month and five instant voice clones. Higher plans add credits, clones, concurrent generation and agent-call capacity, with priority support on Core and technical success manager support on Business.
VoxCPM
VoxCPM is an open-source text-to-speech system whose VoxCPM2 model generates expressive multilingual speech. It supports 30 languages and lists nine Chinese dialects. Voice Design can create a voice from a natural-language description without reference audio, and voice cloning is supported. Output is 48kHz audio, reference audio is accepted at 16kHz, and WAV is listed as an export format. A streaming generation API is available; the repository reports a real-time factor as low as about 0.3 on an NVIDIA RTX 4090. Full and LoRA fine-tuning can adapt the model from 5–10 minutes of audio. Documented deployment includes Python and CLI use, a local web demo, production serving and on-device inference. vLLM-Omni exposes an OpenAI-compatible /v1/audio/speech endpoint, while Nano-vLLM supports concurrent requests. Apple Silicon MPS and C++ inference on CPU, Metal, CUDA or Vulkan are documented. Code and weights use Apache-2.0 and are free for commercial use. Python installation requires Python 3.10 or later but below 3.13, PyTorch 2.5.0 or later and CUDA 12.0 or later. Voice Design and cloning results can vary, and unsupported languages may require testing or fine-tuning. VoxCPM is headquartered in Beijing, China.
