EmotiVoice

EmotiVoice is an open-source text-to-speech engine that generates English and Chinese speech with more than 2,000 voices. Its defining workflow uses prompts to control emotion and style, including happy, excited, sad, and angry delivery. The README also documents personal-data voice cloning, adjustable voice speed, an interactive web interface, batch scripting, and an OpenAI-compatible TTS API.

Users can run the provided Docker image with an NVIDIA GPU, install the project through Conda and pip, or use the Streamlit demo page locally. The project includes pretrained-model setup and command-line inference workflows, and an HTTP API is available for application integration. It is released under the Apache-2.0 license.
