How Kokori Works
Kokori operates as both a desktop application and a local API server. Users can interact with it through the intuitive GUI or via a RESTful API endpoint (http://localhost:5002/tts). By sending a JSON payload with parameters like text, voice, and speed, users can generate audio files instantly. The app handles all processing locally, ensuring fast response times and complete data privacy.
Core Benefits and Applications
Kokori is ideal for developers who want to test text-to-speech functionality without incurring API costs. It's also useful for content creators who need to generate voiceovers or audiobooks. Additionally, its offline nature makes it suitable for environments where internet access is limited or restricted. The ability to choose from a wide range of voices allows users to match the tone and style of their projects effectively.
