Kokoro

Kokoro is an open-weight text-to-speech model and inference library built around the lightweight Kokoro-82M model. It is designed to generate high-quality speech from text while staying fast, compact, and cost-efficient compared with larger TTS systems. The project is useful for developers who want deployable speech synthesis without depending on a closed platform. It can be installed as a Python package and used in applications, scripts, experiments, or production workflows. Kokoro’s Apache-licensed weights make it flexible for personal, research, and commercial use cases. Its main value is delivering practical, accessible voice generation with a small model footprint and a simple developer workflow.
