A proof of concept Android App to test a Breton language speech to text model build using Kaldi and Vosk. It is an offline STT system so the decoding is done on the device. No internet connection needed and no data is sent online.
Check the releases for pre-built binaries.
The process of building the STT model is described here. Helper scripts to build the model can be found there as well, or here
A desktop command-line version is also available here.
