7 Best ChatTTS Alternatives (Self-Hosted)

ChatTTS is a powerful open-source text-to-speech (TTS) model designed specifically for conversational scenarios. With nearly 40k GitHub stars, it generates natural, expressive speech that captures the nuances of daily dialogue including laughter, pauses, and conversational fillers. Unlike traditional TTS systems that produce robotic monotone speech, ChatTTS leverages a deep generative model trained on massive conversational data to deliver human-quality voice synthesis. It supports English and Chinese, offers voice cloning capabilities, and includes a WebUI and OpenAI-compatible API server for easy deployment. The model runs efficiently on consumer GPUs with as little as 4GB VRAM.
