I’m feeling super stupid. I’ve downloaded this and the two fst files aren’t in this image.
Edit: I’ve found the issue. In all of the german images these two dst files are missing. I’ll take these from the en versions and try whether it’s working and report.
I found this:
The ivector extractor had been missing from the acoustic model binary archive. You can download it separately from http://ltdata1.informatik.uni-hamburg.de/kaldi_tuda_de/tdnn_chain_cleaned_tuda_swc_voc126k_ivector_extractor.tar.bz2 or redownload the full archive.
