libvits-ncnn 🎙️

This is an ncnn implementation of the VITS library that supports cross-platform GPU-accelerated speech synthesis.
The project is forked from weirdseed/Vits-Android-ncnn, Thanks to the original author for their contribution.

📖 Usage

1. 🔍 Prepare dependencies

   Get the ncnn static library suitable for your runtime environment from its wiki or ncnn/releases.
   Place it in the root directory ncnn folder like this:

   ncnn
   ├─bin
   ├─include
   └─lib

2. 🛠️ Compile the project

   a. libvits-ncnn
   Execute in the repo root directory:

   mkdir build && cd build  
   cmake .. -DCMAKE_CXX_COMPILER=/usr/bin/clang++ -DCMAKE_C_COMPILER=/usr/bin/clang  
   make

   After compilation, you can find libvits-ncnn.so in the build directory.

   b. vits-cli
   Enter the demo directory and execute：

   mkdir build && cd build  
   cmake .. -DCMAKE_CXX_COMPILER=/usr/bin/clang++ -DCMAKE_C_COMPILER=/usr/bin/clang  
   make

   After compilation, you can find vits-cli in the build directory.

3. 🚀 Run the demo

   In the directory where vits-cli is located, prepare the dependencies required for running:

   a. Download the openjtalk dictionary file and unzip it;
   b. Download the VITS ncnn model, unzip the Atri part to the atri/ directory (for testing the monophonic model), and extract 365_epochs to the 365_epochs/ directory (for testing the multi-tone model).
   c. Download the VITS ncnn params (single/multi directories).

   At this time, the directory has:

   build
   ├─vits-cli
   ├─365_epochs
   ├─atri
   ├─multi
   ├─open_jtalk_dic_utf_8-1.11
   └─single

   Now execute ./vits-cli.

🔧 Main changes
