I just found this. APKs for TTS engines [https://k2-fsa.github.io/sherpa/onnx/tts/apk-engine.html] Main page [https://k2-fsa.github.io/sherpa/onnx/index.html] This is huge! As a german, I use thorsten medium [https://huggingface.co/csukuangfj/sherpa-onnx-apk/resolve/main/tts-engine-new/1.10.26/sherpa-onnx-1.10.26-arm64-v8a-de-tts-engine-vits-piper-de_DE-thorsten-medium.apk] as he simply made the best dataset. Mixing english with german, speaking numbers, single letters, pausing without a “.” but just a linebreak, all those can be essential. And… it is nearly perfect! And all local! This is crazy! eSpeak can finally go to rest!
