About SherpaTTS
SherpaTTS is an Android Text-to-Speech engine based on Next-gen Kaldi using Piper or Coqui voices. Upon launching the app for the first time, it will download your preferred voice model from Hugging Face. Please note that this is the only instance where internet permission is required. Once the model is downloaded, text-to-speech works entirely offline, ensuring your privacy and convenience.
Privacy and F-Droid
F-Droid builds SherpaTTS from its published source code and flags anti-features such as ads, tracking or reliance on non-free services.
