Show HN: ChatTTS – A Conversational Text-to-Speech Model for Lifelike Dialogue As a developer working on conversational AI systems, I've always been fascinated by the potential of text-to-speech technology to bring virtual assistants and chatbots to life. However, during my work on a voice-enabled chatbot project last year, I encountered a frustrating limitation – most existing TTS models lacked the natural expressiveness and nuance required for truly engaging dialogue. The available models often sounded robotic, struggled with proper intonation and prosody, and lacked the ability to convey subtle elements like laughter, pauses, and interjections – all crucial components of natural conversation. I realized there was a pressing need for a text-to-speech model specifically designed for dialogue scenarios, one that could capture the nuances of human speech and deliver a truly lifelike conversational experience. Driven by this realization, I embarked on an ambitious journey to develop ChatTTS, a conversational text-to-speech model tailored for dialogue applications. Over the course of nine months, and after overcoming numerous challenges in data acquisition, model architecture, and fine-tuning, I finally succeeded in creating a powerful TTS system that could synthesize natural and expressive speech, supporting multiple languages and speakers. ChatTTS boasts several key features that set it apart: 1. Conversational TTS: Optimized for dialogue-based tasks, enabling natural and expressive speech synthesis with support for multiple speakers, facilitating interactive conversations. 2. Fine-grained Control: The ability to predict and control fine-grained prosodic features like laughter, pauses, and interjections, adding an extra layer of realism. 3. Improved Prosody: Surpassing most open-source TTS models in terms of prosody, delivering a truly lifelike experience. I'm thrilled to finally share Chat TTS with the Hacker News community. I invite you all to try it out and provide feedback. Let's revolutionize the way we interact with conversational AI! https://chattts.me June 2, 2024 at 02:47AM
