KokoroOnnx .NET

A .NET port of the Kokoro TTS (Text-to-Speech) system using ONNX Runtime. This library provides a simple interface for synthesizing speech from text using pre-trained ONNX models.

Features

  • Cross-platform support (.NET 8.0, .NET 9.0)
  • Support for multiple voices
  • GPU acceleration support (via ONNX Runtime GPU)

Prerequisites

  • .NET 8.0 SDK or later
  • ONNX model files (compatible with the original Kokoro TTS)
  • Voice files (phoneme dictionaries, etc.)

Installation

Add the KokoroOnnx NuGet package to your project:

dotnet add package KokoroOnnx

Usage

Basic Usage

using KokoroOnnx;

    try
    {
        Console.WriteLine("Synthesizing...");
    
        // Synthesize speech
        Kokoro.Create(
            model: "models/kokoro_model.onnx",
            text: text,
            filename: "output.wav",
            voice: "jf_gongitsune",
            isPhonemes: true);
    
        Console.WriteLine($"Audio saved to: output.wav");
    
        // Play the audio
        Kokoro.PlayAudio("output.wav");
    }
    catch (Exception ex)
    {
        Console.WriteLine($"Error: {ex}");
    }

GPU Acceleration

To enable GPU acceleration, make sure you have the appropriate CUDA/cuDNN versions installed.
