About

Chatterbox is a free, open source voice cloning AI model developed by Resemble AI, licensed under MIT. It enables zero-shot voice cloning using just 5 seconds of reference audio, eliminating the need for training. The model offers expressive speech synthesis with unique emotion control, allowing users to adjust the intensity from monotone to dramatically expressive with a single parameter. Chatterbox supports accent control and text-based controllability, ensuring high-quality, human-like text-to-speech conversion. It operates with faster-than-real-time inference, making it suitable for real-time applications, voice assistants, and interactive media. The model is built for production and designed for developers, featuring simple installation via pip and comprehensive documentation. Chatterbox includes built-in watermarking using Resemble AI’s PerTh (Perceptual Threshold) Watermarker, embedding data imperceptibly to protect generated audio content.

About

Inworld TTS is a state-of-the-art text-to-speech platform designed to deliver ultra-realistic, context-aware speech synthesis and precise voice-cloning capabilities at a radically accessible price. The flagship model, TTS-1, is optimized for real-time applications and supports low-latency streaming (first audio chunk in ≈200 ms) as well as multiple languages (including English, Spanish, French, Korean, Chinese, and more). Developers can use instant zero-shot voice cloning (5-15 seconds of audio) or professional fine-tuned cloning, add voice-tags for emotion, style, and non-verbal sounds, and switch languages while preserving voice identity. The larger TTS-1-Max model (in preview) offers even more expressive speech and multilingual strength. The platform supports both API and portal access, streaming or batch mode, and is designed for everything from interactive voice agents and gaming characters to branded audio experiences.
