The following datasets can be used to train a language-independent LPCNet model. A good choice is to include all the data from these datasets, except for hi_fi_tts for which only a small subset is recommended (since it's very large but has few speakers). Note that this data typically needs to be resampled before it can be used. https://www.openslr.org/resources/30/si_lk.tar.gz https://www.openslr.org/resources/32/af_za.tar.gz
