In their own words
GPT-SoVITS
GPT-SoVITS is a free WebUI for few-shot voice conversion and text-to-speech. It can generate speech from a five-second vocal sample, or use one minute of training data to improve voice similarity and realism. Cross-lingual inference supports English, Japanese, Korean, Cantonese, and Chinese. The WebUI includes tools for separating accompaniment, segmenting training sets, multilingual speech recognition, and labeling text. Speech-recognition options include Fun-ASR-Nano, SenseVoice, classic FunASR, and Faster Whisper. The repository also provides an API with GET and POST inference endpoints that return WAV audio streams on success. Installation instructions cover Windows, Linux, and macOS, with Docker Compose services in full and Lite variants. The Lite image omits ASR and UVR5 models; UVR5 models must be downloaded manually, while ASR models download as needed. On macOS, the project temporarily uses CPUs because it reports significantly lower quality from models trained with Mac GPUs. GPT-SoVITS is released under the MIT License and links to Chinese and English user guides.
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.
