[csukuangfj]

Steps to run it on the iOS simulator inside xcode

1. Download and build the code

mkdir -p ~/open-source/
cd ~/open-source
git clone https://github.com/k2-fsa/sherpa-onnx
cd sherpa-onnx
./build-ios.sh

2. Download the tts model

Please refer to
https://k2-fsa.github.io/sherpa/onnx/tts/pretrained_models/kokoro.html#kokoro-en-v0-19-english-11-speakers
to download models.

mkdir -p ~/open-source/icefall-models
cd ~/open-source/icefall-models

wget https://github.com/k2-fsa/sherpa-onnx/releases/download/tts-models/kokoro-en-v0_19.tar.bz2
tar xf kokoro-en-v0_19.tar.bz2

Note that you can put model files anywhere you like. We use ~/open-source/icefall-models as an example
